Edit a PDF
Open a PDF, add what is missing and save a checked copy; the file never leaves your device. You can change existing text where its font allows it; otherwise we show you the substitute before you save. You can also add text, pictures, notes and a signature, fill forms and reorder pages.
Updated November 6, 2026
How it works
- Drop a PDF or choose one; it opens here, on your device, with a note on what can be edited.
- Add text, pictures, notes or your signature, fill the form fields, rotate or reorder pages. Undo anything with Ctrl+Z; your work is kept as a draft in this browser.
- Save: the editor checks the new file page by page, then downloads it. Compare before and after if you like.
When the editor is the right tool, and when a simpler one is faster
Open the editor when the change is inside the page: a date to correct, a form to fill, a signature to place, a paragraph to rewrite, a name to black out, a picture to swap. For a job that touches whole files or whole pages, a dedicated tool is quicker and asks fewer questions: Merge PDF to combine files, Compress PDF to make one smaller, Add page numbers for numbering, Rotate PDF or Split PDF for pages. The editor opens one file at a time; the size it can take depends on the memory of the device you are on, and it tells you before the file opens.
On a phone the editor works in the browser for filling, signing, notes and small text changes. A long or picture-heavy file is easier on a computer, and the editor says so when a file is too large for the phone.
Forms and signatures in practice
A form with fields is filled by tapping each field; a form without fields gets text where you place it, or new fields you draw yourself. A signature can be drawn with a finger or a mouse, typed in a handwriting style, or placed from a picture of your signature; a .p12 or .pfx certificate signs the file in the format other PDF programs read. The Signatures panel reports what it can check on your device, which is whether the file changed after signing, and is honest about what it cannot: whether the signer is who they claim to be.
Good to know before you start
Every change is a step you can undo, and the steps are kept as a draft in this browser for 7 days, so a half-finished form survives a closed tab. Save checks the new file page by page before it is downloaded, and Compare shows before and after side by side. The editor downloads its own code once and then works without a connection; the file itself never leaves your device.
Why people use it
Free, no account
Every tool is free, with no sign-up, no e-mail address and no limit on how often you use it.
Your files stay on your device
The browser opens the file and processes it in memory, on your device. Nothing is uploaded, so nothing can be kept, leaked or looked at.
No watermark
The result is yours as it is: no watermark, no branding, no trial version.
Any device
A phone, a tablet or a computer with a current browser is enough: no app to install, no software to update.
Works offline after the first visit
The browser keeps the pages and their engines, so a tool you have opened once keeps working without a connection.
Open-source engines
The code that does the work is open-source software, named on the Licences page, running as WebAssembly in your browser.
Why it is private
Everything you type or drop here is handled by your browser, on your device. Nothing is uploaded. To verify, open your browser's developer tools, go to the Network tab, and use the tool: you will see no request carrying your data.
While a file is being processed, the counter under the result shows the page's network traffic: 0 requests and 0 B for your data.
How to check it yourself, step by step
What you can check yourself
Open your browser's developer tools on the Network tab before you drop a file: while the tool works you will see no request carrying your data, and the counter under every result shows the page's own measurement.
The site sets no cookies, so there is no cookie banner. Anonymous usage counts and error reports without file names are the only things that leave the page, as the privacy policy describes.
Every change goes through thousands of automated tests in three browser engines, including a guard that fails a test if a single byte of a file leaves the page.
Frequently asked questions
- Which text can I edit?
- Lines whose font is embedded in the file as TrueType or OpenType, the usual case for PDFs made with Word, LibreOffice or Google Docs: you edit with the original font, and the alignment and the rest of the page stay as they were. Many files carry only the letters they use; if you type a letter that is not among them, we show you the line with a substitute font next to the original before you save, and you keep it or discard it. Text in pictures (use Text recognition instead), text drawn as shapes and text used as a mask for other content cannot be edited; you can cover it and write new text. A whole paragraph can be re-laid in its own space when you add or remove words; if it gets longer, it can push the paragraphs of the same column down — never onto the next page — or the editor shows you where it stops. Text set in an older font type (Type 1), common in files made with LaTeX, is edited with its original letters when the editor can convert the font; when it cannot, that line is written with a substitute font, shown before you save.
- Where does my file stay?
- On your device. The PDF is opened and saved by your browser; nothing is uploaded. The editor downloads its own code once and then works offline. Drafts are kept in this browser only.
- What happens with a signed document?
- The editor tells you on opening what the signature allows. Where the document permits it, filling and notes are added to the file without touching what was signed; anything else needs a copy without signatures, which you choose explicitly. The Signatures panel checks each signature on your device and says whether the document has not been modified since signing, was modified only by filling and annotating, or was modified in content; the signer's identity is not verified against an authority. Whether another program still shows the signature as valid is for that program to decide.
- What is a draft and how long is it kept?
- Every change is a step with its time; close the tab and the steps and the file are kept in this browser as a draft, so you can continue later or go back to an earlier step. Drafts are deleted after 7 days or when you discard them, and they never leave your browser.
- Is redaction permanent?
- Yes, in the saved file: the text, the picture pixels and the notes under each box are removed from the file, not just covered; old versions kept inside the file are deleted, and the file information (title, author, program) is replaced. After saving, we re-read the file and confirm that nothing remains in those areas; if we cannot confirm it, the file is not offered and we tell you what you can do instead. Two honest limits: the font left in the file can still show which letters existed in the document, not which words; and nothing can be removed from copies already sent.
- Can I edit a scanned PDF?
- Yes, in two ways. “Make searchable” keeps the page as it is and adds the recognised text underneath, so you can find, select and copy it. “Turn into an editable document” rewrites the recognised text as paragraphs you can edit, with a substitute font, and shows you the original next to the result before you keep it; the look of the page changes, and the original typeface is not kept. Recognition is never perfect, so the comparison is there for you to check. Handwriting, stamps and tables without lines stay pictures; slanted text is written upright. Both run on your device, with the language models fetched from this site once.
- Can I edit the drawings in a PDF?
- Lines, shapes and diagram parts drawn as vector graphics can be selected on their outline, then moved, resized, recoloured or deleted, with their line width and style changed; a group of drawings moves together. Some drawings can only be moved or deleted as a whole, not recoloured: those filled with a repeating pattern or a colour gradient, and those blended with what is under them; when the file does not allow the move, such a drawing can only be deleted, and the editor says so. Two kinds accept no change at all, and the editor says so: a drawing that also marks where other content is visible, and a drawing inside a reusable block shared with other pages; you can cover them. Text drawn as shapes is a drawing, not text.
- Are the header, footer and watermark editable afterwards?
- The header and footer are written as ordinary text on each chosen page, with the page number, number of pages, date, title or file name filled in, so afterwards you edit, move or delete each line like any text you add. A single text watermark is also text. A tiled or picture watermark is one block per page that you can move or delete, not change inside; to change it, delete it and add it again. All of these are new content on top of the page; the existing content is not touched.
- Can I add or change form fields?
- Yes. Choose Add field, pick a type — text, checkbox, radio button, list or drop-down, signature — and drag a box where it should go; a form that has no fields gets them the same way. Select a field to move or resize it, rename it, make it required or read-only, give it several lines or one character per box, edit the options of a list, choose the mark of a checkbox, change its colours and font size, or move it in the tab order; each change is a step you can undo. A digitally certified document refuses new fields and field changes — the editor says so, and the way around it is a copy without signatures; a form in an older form format (XFA) can still be filled but not changed. Fields locked by a signature stay as they are.
- Can I edit tables?
- Tables in a PDF come in two kinds, and the editor tells you which it found. A table with a structure in the file — the usual case for files made with Word or LibreOffice with accessibility tagging on — lets you edit any cell, insert a row below or delete a row; when a cell needs more lines, its row grows and the rows below, the table's lines and the paragraphs under the table move down. A table drawn only with lines, without a structure, is detected from those lines and from the text aligned in them: you can edit its cells, but rows cannot be added or deleted yet. A table in a scan stays a picture until you run Text recognition, and then becomes lines of text, not a table.
- Can the editor check a digital signature?
- Yes, on your device. For each signature the editor hashes the signed part of the file and checks the signature with the certificate inside the file, then compares what came after it: it tells you who signed and when, and whether the document has not been modified since signing, was modified only by filling and annotating, or was modified in content. Two honest limits: the signer's identity is not verified against an authority, because the browser has no store of trusted certificates — so the editor never says a signature is legally valid — and time stamps are shown, not verified. Older or unusual algorithms are reported as not checked, with the reason.
- Can I sign with my own certificate?
- Yes, with a .p12 or .pfx file and its password. The file is read in your browser: the private key goes into the browser's memory until you close the document, the password is used once and not kept, and nothing is sent anywhere. The signature is written when you save, as the last thing added to the file, in the PAdES format other PDF programs read, visible in a box or invisible; the editor then checks it with the same check it applies to any signature. A time stamp from an authority is not added, so the signing time is your device's clock. Saving the file again by rewriting it removes the signature; changes added to the file as a revision keep it.
- Can I save as PDF/A?
- You can save as PDF/A-2b, the archival form of PDF: fonts embedded, colours defined, file information in a standard form, nothing that depends on an outside program. The whole file is rewritten, so existing signatures are removed, and the result is checked before it is offered; when the check fails, you get the file with the list of what it still violates, most often a font the original does not embed — the editor does not re-embed the original's fonts or convert its colours. Text you add is written with embedded fonts, so it never breaks conformance by itself. Tagging for accessibility is a separate option: it marks the text and pictures you added, with the document language and alternative texts, and is not a full accessibility certification.
