17 Best Online PDF Editors in 2026 (Free and Paid)

Fixing one date in a PDF should take a minute. You open an online PDF editor, change the date and press Download, and the site asks for a Pro plan. Or the download works, the new date looks right and the old one is still inside the file for anyone who searches it.

I ran into both while testing the same 2-page proposal. Smallpdf let my whole correction go through and asked for Pro only at the download step. DocFly’s Blackout put a black box over a $6,000 total, and when I searched the downloaded file, it still found $6,000. The best online PDF editors tell you three things before you spend 10 minutes on a file:

• whether they can change the original text or only add new text on top
• what the free plan lets you download
• where your file goes after you upload it

For changing words that are already in a PDF, my pick is PDF Candy. It edits existing lines for free with no account and no watermark, and on the test file it kept the original font, which Sejda didn’t.

If the file shouldn’t leave your computer, I’d use PDFgear. Its online editor works inside your browser without uploading anything, and its free desktop app handles the text edits the browser version can’t.

For filling and signing a form without an account, SimplePDF is the quickest. When something has to disappear for real, PDF24’s Redact tool removes the text instead of covering it.

I tested every editor that works without an account on the same file, a 2-page proposal with:

• embedded fonts, the way a word processor exports them
• a pricing table
• a link
• three form fields on the second page

Everything I report about a result comes from the file I downloaded afterwards. The editors that need an account I compared on their published plans and limits, and their entries say so.

What to Check Before You Upload a PDF

There are generally four things that decide whether a free PDF editor will work for your file. I want you to check these before you upload anything, because most bad results trace back to one of them.

Editing Text vs Adding Text

Adding text puts a new text box on top of the page, like your name on a blank line or a date in an empty field. Every editor on this list can do that for free.

Editing text changes the words already inside the PDF, like a wrong date or a typo in a sentence. Fewer editors can do this, and they do it in two different ways:

• Line by line: PDF Candy, Sejda and TinyWow open one line at a time. A replacement of the same length looks fine. A longer one pushes past the right margin, because nothing moves down to the next line.
• Paragraph by paragraph: iLovePDF’s Edit mode, Smallpdf and Adobe detect the whole paragraph and reflow it, so the extra word wraps the way it would in a word processor.

When I changed one word from “six weeks” to “eight weeks”, the result came back three different ways. If a sentence changes length, use an editor that reflows the paragraph. For a date or a figure of the same length, the free line editors are enough.

Covering Text vs Removing It

This is the part that worries me the most, because the mistake stays invisible until someone searches the file. A white box with new text on top looks exactly like an edit, and so does a black box over a number. Neither one removes anything, and anyone who searches the file or copies its text gets the original words back.

Sejda says this plainly on its own editor: Whiteout hides text without removing it and isn’t suitable for redacting sensitive data. DocFly’s Blackout behaved the same way in my test. When something has to go for good, use a redaction tool that deletes what is underneath, like PDF24’s Redact, which flattens the redacted pages into images when it saves. The trade-off is that the text on those pages can’t be selected afterwards. Search the downloaded file for the old words before you send it.

Free Editing vs Free Download

Most free plans let you do the work. The limit usually shows up at the download.

Smallpdf let me finish the full correction, reflowed the paragraph and then stopped me at Download with this screen. That screen must be doing very well for their sales team. Other editors cap the number of downloads instead:

• DocFly: 3 exports a month, and printing, emailing or saving to Google Drive each count as an export
• Lumin: 3 completed documents a month, where sharing, downloading, printing or syncing completes one
• DocHub: 3 uses a month, shared across editing existing text, signing, templates and share links
• Xodo: 1 action a day on the free plan

So before you put 10 minutes into a document, look for a crown or a Pro badge on the tool you are about to use. I would also make one small edit and download it before doing the whole file. It is wise to find the paywall while the cost is one sentence.

Where Your File Goes

The same click on Upload means three different things depending on the editor:

• It stays in your browser: PDFgear’s online editor and SimplePDF process the PDF on your device and never upload it.
• It goes to the vendor’s server and is deleted on a timer: Sejda and PDF Candy after 2 hours, iLovePDF within 2 hours, PDF24, Smallpdf and TinyWow after 1 hour, DocFly after 24 hours for files uploaded without an account. Adobe deletes it unless you sign in and save it.
• It stays in your account: DocHub, Lumin and Canva keep the file in your cloud account until you delete it.

A deletion timer only covers how long the file sits on someone else’s server. For contracts and client documents, I’d use a browser-only editor or a desktop app. The desktop Acrobat alternatives cover the offline options in more detail.

Best Online PDF Editors for Changing Existing Text

I have grouped the editors by the job they do, starting with the six that can change words already in the PDF without a paid plan. The first three carry my gold, silver and bronze awards. Each comes with a condition: a usage limit, an account, an install or, in iLovePDF’s case, a Premium label on the feature.

PDF Candy

PDF Candy is the free online PDF editor I’d use to correct words that are already in a PDF. Its Text tool doubles as the edit tool, so clicking an existing line opens it for typing, with no account and no watermark on the download.

On my test proposal, both changes went through and the edited lines kept Georgia, the original font. The cost was spacing. The longer line stretched its word gaps and ran about a quarter inch past the right margin, because PDF Candy edits one line at a time and nothing flows down to the next line. The link and all three form fields survived.

• Free files up to 50 MB, with page and hourly limits PDF Candy doesn’t put a number on
• Files deleted from its servers within 2 hours
• OCR is free and needs no sign-up
• Paid: $6 a month for the web version, or $99 once for desktop and web (the desktop app is Windows only)

PDF Candy also markets its Whiteout tool for hiding personal data. Treat that as covering, for the reasons above. For a date or a figure of the same length, this is the editor I’d open first.

Sejda

Sejda is the runner-up for existing text and the editor with the clearest free plan. It opens with the Text tool selected, and clicking any line turns it into an editable box.

Both of my test edits went through, and the download needed no account and carried no watermark. Sejda did swap the font: both edited lines came back in DejaVu Serif instead of Georgia, so the corrected sentence looked wider than the lines around it, and the longer line ran almost to the edge of the page. The old words were gone from the file, and the link and form fields still worked.

• Free: documents up to 200 pages or 50 MB, and 3 tasks an hour
• Files deleted after 2 hours
• Form filling, form field creation, signatures, find and replace, and free OCR up to 10 pages per task
• Web Week Pass: $5 once for 7 days; Web Monthly: $7.50 a month; Desktop and Web: $63 a year
• Sejda Desktop runs on Mac, Windows and Linux, free for 3 tasks a day

What I like about Sejda is everything around the edit: forms, find and replace and a desktop app with the same tools. When you have a batch of documents to fix in one sitting, I’d buy the $5 week pass instead of a subscription. It is the cheapest way to remove the hourly cap.

iLovePDF

iLovePDF gave me the cleanest text edit of any tool I tested, with one condition attached. Its editor has two modes: Annotate, which is free, and Edit, which carries a Premium crown.

When I made the same change in Edit mode, it reflowed the whole paragraph, kept Georgia and stayed inside the margin, and the date change kept the font too. The download didn’t ask me for an account and carried no watermark. iLovePDF’s own tooltip still calls existing-text editing a Premium feature, so I’d treat the free access as a bonus that may not be there next month.

• Annotate mode is free: add text, shapes, comments and highlights
• Edit PDF accepts files up to 100 MB, one file per task
• Free OCR up to 50 pages, plus free Sign, Redact, Forms and page organizing tools
• Files deleted within 2 hours; iOS and Android apps available

If the free Edit mode disappears, iLovePDF is still a good free toolbox for the jobs around editing. The browser PDF toolkit covers tools like it for merging and compressing.

TinyWow

TinyWow edits existing lines without an account, but it gave me the least predictable result of the lot. Clicking a line with the Text tool opens it in its original box, and the box keeps its width.

When “six weeks” became “eight weeks” in the editor, the line wrapped inside its fixed box and “weeks,” dropped onto the next line, right over the text already there. The download then asked me to pass a reCAPTCHA check, with a “Tired of Captchas?” upgrade offer beside it.

• Free use has a daily limit that TinyWow doesn’t publish
• Files deleted 1 hour after upload
• PDF Unlimited: $9 a month, or $6 a month billed yearly

I’d use TinyWow only for a swap of the same length, like one date for another. For anything longer, check the line spacing in the downloaded file before you send it.

DocHub

DocHub is the one to pick if your PDFs already live in Google Drive or Gmail. It needs a free account, so I compared it on its published plan. That plan includes real existing-text editing, but it sits inside a shared allowance.

• Free: 3 uses a month, shared across editing existing text, self-signing, signature requests, templates and share links
• Opens files from Google Drive, Gmail, Dropbox, OneDrive and Google Classroom
• No watermark on edited documents, according to DocHub
• Basic: $8 a month billed yearly ($11 monthly); Pro: $12 a month billed yearly ($16 monthly), with a 30-day Pro trial

If you are a student or a small office already living in Google Workspace, DocHub is where I’d start. Just keep an eye on the count, because three uses a month runs out quickly once you start signing documents too.

Stirling PDF

Stirling PDF is for people who want the editor on their own machine or their own server. It is an open-core PDF toolkit, and its latest major release moved the text editor out of alpha.

• Manual editing in the PDF editor is free and unlimited
• The hosted free plan adds 1,000 monthly credits for automation and AI tasks, with no card required
• The desktop app’s local mode keeps files on your device; OCR and Office conversions need a connected server or Stirling’s cloud
• Self-hosting with Docker is free for up to 5 users; the Team plan is $99 a month or $999 a year

Stirling PDF needs an account or an install, so I compared it on its published plans instead of the test file. It is what I’d suggest to an office that wants a shared PDF toolbox and doesn’t want client files on someone else’s server.

Best Free Online PDF Editors for Forms, Notes and Signatures

These six don’t change the original text in the browser. They add text on top of the page and handle forms and signatures, and most of them do it without an account.

PDFgear

PDFgear is my pick when the file shouldn’t leave your computer. The online editor processes the PDF inside your browser, so nothing is uploaded and no account is needed.

• Online: files up to 100 MB, with no limit on the number of files
• No ads and no watermark, according to PDFgear
• Text boxes, images, comments, shapes, stamps, signatures, form fields and page organizing
• Free desktop app for Windows and Mac that edits existing text and runs OCR
• Free iOS and Android apps

When I clicked Edit PDF on my test file, PDFgear brought up a prompt to get its app for text edits, which is the honest boundary. If you can install an app, PDFgear is the best free route overall: the browser for quick forms and the desktop app for real corrections.

SimplePDF

SimplePDF is the fastest way to fill and sign a PDF without an account. The free editor keeps the document in your browser, and it has no usage limits for individuals and no watermark.

• Text fields, checkboxes, signatures, pictures and white backgrounds
• Merge files, delete pages and rotate pages
• A Detect fields button that finds the blanks in a form
• Paid plans are for businesses that embed the editor in their own site, from $99 a month

SimplePDF has no way to edit existing text, so I tested the usual workaround. A white-background text field over “six weeks,” looked like a clean fix, but the PDF I downloaded still contained “six weeks,” underneath, and the new words came out in a sans-serif font. I like it a lot for forms and signatures, and I’d leave corrections to the editors above.

PDF24 Tools

PDF24 Tools is the free toolbox I’d keep bookmarked. Advertising pays for it, so there is no registration and no usage limit, and its Redact tool deletes whatever you mark.

• The editor adds text, images and shapes; to change existing text, PDF24 suggests converting to Word first
• Files processed on servers in Germany and deleted after 1 hour
• Separate free tools for signing, OCR, redaction, merging and compression
• PDF24 Creator is a free desktop app for Windows that works offline

PDF24’s editor is basic. I’d keep it bookmarked mainly for the Redact tool and the converters around it.

PDFescape

PDFescape is the old reliable for forms. The free online version needs no registration and adds no watermark, and it can create new form fields as well as fill existing ones.

• Free online: files up to 10 MB and 100 pages, with ads beside the editor
• Text, Whiteout, Image, Freehand, Link and Form Field tools, plus annotation and page tools
• Files stored in a US data center
• Editing existing text needs PDFescape Premium, a Windows desktop app, at $2.99 a month billed yearly

For building a simple fillable form, PDFescape is still my free pick. If you collect the same details from people again and again, an online form builder will save you more time than a fillable PDF.

DocFly

DocFly works for the occasional document. It needs no sign-up and gives you 3 free exports a month, and anything that takes the file out of DocFly counts as an export.

• Files uploaded without an account are deleted after 24 hours
• Text, Whiteout, Blackout, Image, Signature, Draw, Link and Highlight tools, plus a form creator and page organizer
• DocFly’s own advice for changing text is to cover the old text and type new text on top
• Pro: $7.99 a month, or $3.99 a month billed yearly; students and teachers get 10 free downloads with a school email

The file I downloaded had no watermark, and the link and form fields survived. The Blackout box I drew over the $6,000 total did not remove the number, so I’d keep DocFly for forms and notes and use a real redaction tool for anything private.

PDF2Go

PDF2Go suits students and teachers who can verify a school email. My test file opened without an account in an add-only editor, and the free plan runs on credits.

• Text, whiteout, highlight, shape and image tools on top of the page
• A handful of free credits without an account; 30 welcome credits with a free account, refilling daily
• Paid tools free for verified students and teachers through its education program
• Starter plan: $8 a month

I’d bother with PDF2Go’s school-email check only if you work with PDFs through a whole semester. The best PDF apps for students cover reading and annotation apps for the same job.

Paid and Account-Based Online PDF Editors

These five need an account or a paid plan for the edits that matter. One of them makes sense when you edit PDFs every week and the subscription saves you more time than it costs. The last three need an account, so I compared them on their published plans.

Smallpdf

Smallpdf‘s Edit Text mode reflowed my test paragraph neatly in the editor, and it sits behind Pro. It detects whole paragraphs and lets you finish the edit, then asks you to upgrade at the download step.

• Free: add text, images and highlights, with a daily download limit
• Basic OCR, signing and redaction are free within that limit; OCR conversion to Word or Excel is Pro
• Files deleted after 1 hour
• Pro: $15 a month, or $120 a year in the US

I am happy to recommend Smallpdf once you have paid for it. On the free plan, I’d use it for annotation and the utilities, and decide about Pro before starting a text edit.

Adobe Acrobat Online

Adobe Acrobat Online is Adobe’s free browser editor for marking up a PDF. Adobe says it doesn’t change existing body text and that downloading needs a free Adobe account.

The Edit panel pushes a 7-day free trial for unlimited editing. When I tried it, the browser editor still let my existing-text change through and downloaded it without asking me to sign in, after a prompt for access to local fonts. The edited words came out in Source Serif Pro inside Georgia lines. Adobe’s own page promises less than that, so I wouldn’t plan around it.

• Free: comments, sticky notes, text boxes, highlights, drawings and signatures
• Acrobat Standard: $14.99 a month on an annual plan ($24.99 month to month)
• Acrobat Pro: $19.99 a month on an annual plan ($29.99 month to month), with a 7-day free trial
• Free Acrobat Reader and mobile apps for viewing, commenting and signing

Canva

Canva is for redesigning a PDF. It imports the file as an editable design, so you can change the text, swap images and rework the layout of a brochure or worksheet with a free account. For correcting a clause in a contract, the editors above do a cleaner job.

• Imports PDFs up to 500 pages and 300 MB
• Unsupported fonts may be replaced, and layouts can shift slightly after import
• Scanned PDFs import as a single flat image with nothing to edit
• Desktop app for Windows and Mac

I’d reach for Canva when the PDF is something you designed and want to refresh, like a downloadable guide. My notes on lead magnets that convert cover what to put in one.

Lumin

Lumin is a document workspace with a small free allowance. Editing existing text is not part of the free plan.

• Free: 3 completed documents a month, and sharing, downloading, printing or syncing a file completes it
• Free tools: text boxes, shapes, images, drawing, highlighting, signing and page organizing; files under 20 MB
• OCR from Pro; fillable fields and redaction from Business
• Starter from $9 a month; Pro $19 a month per team, billed yearly

Lumin makes sense if your team already shares documents there. For a one-off fix, the free editors earlier in this list give you more.

Xodo

Xodo gives you a sample on the free plan: 1 action a day on a limited set of web tools. Its Edit PDF Text tool changes existing text, with advanced editing reserved for paid plans.

• Most tools process files on your device; uploaded files are deleted after 1 hour
• The 3-day trial requires a payment method
• Xodo Web: $10.99 a month or $39.99 a year

At $39.99 a year, Xodo Web is the cheapest annual route here to a full browser editor. Set a reminder if you start the trial, because it asks for a card.

Edit a PDF in Google Docs or Word

Before paying for anything, there is one more free route. Google Docs and Word both convert a PDF into an editable document, and you can save it back as a PDF afterwards. It works well for a plain letter or a text-heavy page and badly for anything with a layout.

• Google Docs: right-click the PDF in Google Drive and open it with Google Docs. Google says the file should be 2 MB or smaller and that lists, tables, columns and footnotes are not likely to be detected.
• Word: Word for the web is free with a Microsoft account. Word converts the PDF into a document, and Microsoft warns that it might not look exactly the way it did as a PDF.

For a document with tables or a designed layout, a dedicated converter does a better job, and these apps to convert PDF to Word handle layouts better than Docs.

Online PDF Editors I’d Skip

You will see these three in other lists. Each one has a reason to leave it out of a free-first shortlist:

• PDFLiner: no free plan. Saving the edited PDF opens a payment window, and the options are $29 for a single document or a subscription from $10 a month billed yearly.
• Xara Cloud: it does in-line text editing, but a free account is limited to 5 document downloads in total, and its PDF to Word conversion is still marked coming soon.
• PDF Bob: free and watermark-free, but it only adds new text, and signing and hyperlinks are still marked coming soon.

How to Check an Edited PDF Before Sending It

The editor’s preview shows what the editor thinks happened. The downloaded file is what your client gets, so check that one:

• Open the downloaded PDF in a normal viewer, not the editor tab.
• Search the file for the old wording. If search finds it, the old text is still in the file.
• Compare the edited line with the lines around it: font, size, word spacing and the right margin.
• Click every link and type into every form field to confirm they still work.
• For a scanned page, run OCR first. Without it, there is no text to edit, only a picture of text.
• If the file is over a free size limit, reduce the PDF file size before uploading instead of paying for a bigger limit.
• If the document needs other people’s signatures, use e-signature software so you get a record of who signed and when.

FAQs on Online PDF Editors

Final Remarks

If you ask me for one rule, choose the editor by the change you need to make. For a word or a date inside the text, I’d start with PDF Candy and keep Sejda as the backup when you need its form tools or find and replace. SimplePDF and PDFgear keep forms and signatures on your device, and anything that has to disappear needs a real redaction tool and a search of the file afterwards.

Whatever you pick, open the downloaded file before you send it. That one check catches the font swap and the covered number before your client does.
