Fill, Sign & Edit PDF
Fill and sign a PDF, or click a line of printed text and retype it. Whiteout, highlight, shapes and a signature you draw, type or upload sit in one toolbar.

Fillable forms open with their fields ready. Any other PDF opens for marking — and printed lines can be retyped.

Marks, drawings and signatures are drawn on permanently either way. Flatten also bakes the field answers in and removes the editable fields.
How to use
- Drop the form into the PDF form box. Genuine fields come back as controls sitting over the page and the file card counts them. If the file has none, it says so, and the toolbar is what you use instead.
- Work down the page, then press Fill & download. Tick Flatten the form fields first if the answers should stop being editable, and switch to Edit text if a line that was already printed needs to change.
About this tool
Fill and sign a PDF the way you'd fill one on paper, except the handwriting comes out straight. Hand over a form and the tool renders it, digs out the real AcroForm fields inside, and puts a working control on each one: text boxes, checkboxes, radio groups, dropdowns, multi-select lists. Whatever the file already holds arrives prefilled. Required fields are outlined so you don't skip one, read-only fields show their value but refuse input, and the file card counts what turned up, like 9 fields found. A longer document shows one page at a time, with every page waiting as a thumbnail in the rail beside it.
Edit text is the part people write to me about. Switch to it and every line the page can select becomes clickable. Click one and it opens as a box carrying the original words at the original size, colour and style, all read out of the document's own font data. Retype it and click away. The page repaints from the edited file, and your change shrinks to a small marker you can click to open it again. On download the tool goes into the page content stream, deletes the original text operator and writes yours back, using the document's own embedded font when that font's subset covers the characters you typed and a metric-matched substitute when it doesn't. If a file's internals make the splice risky, it covers the old line and prints over it instead. The status line names which of the three happened and how many, like 2 edited in the original font, 1 covered.
Scanned and flattened pages have no fields to find, so the toolbar's Type and Mark groups handle those: Text, Date, Check and Cross, then Whiteout, Highlight, Box, Line and Draw. The options dock under the page follows what you're doing. With a tool armed it sets what the next mark will look like; with a mark selected it restyles that one mark. Text sizes run from 6 to 96 pt and start at 14. Stroke thickness goes 0.5 to 12 pt. Images take opacity in five percent steps and rotation from -180 to 180 degrees. The highlighter lays yellow down at 40 percent opacity, and a whiteout box samples the page colour where it lands, which is what makes it vanish into tinted or aged paper.
Signing takes one of three routes. Draw on the pad with a mouse or a finger, type your name and pick Script, Signature or Serif, or upload a photo of a signature you already have on paper. For that last one, tick Remove background and a 4.6 MB model downloads once, cuts the paper away and leaves the ink behind. Then click where the signature belongs and drag a corner until it sits on the line. Documents like these carry a name, an address, sometimes an account number, which makes this the one page where it's worth spelling out what happens to the file: it is opened, edited and re-saved by JavaScript running in this tab, and there is no upload step anywhere in that path.
Flatten the form fields, the checkbox right above Fill & download, decides whether your answers stay live. Leave it off and the fields in the file you get are still editable, which suits a form going round for one more pass. Tick it and each answer is painted into the page and the field itself deleted, which is what you want for the copy someone else opens. Marks, drawings and signatures are baked in either way. Press Fill & download and the file arrives under your own name with -filled on the end, so lease.pdf comes back as lease-filled.pdf. When something can't be done it tells you: a form that refused to flatten, or a character the PDF's built-in font has no glyph for.
Good to know
- XFA forms won't open. They are dynamic XML forms rather than AcroForm ones, a handful of government and bank portals still hand them out, and pdf-lib has no way to read them. The tool spots one and names the problem instead of showing you a blank page.
- A whiteout box hides, it does not remove. The text underneath is still in the file and still extractable, and an Edit text change falls back to that same covering whenever the content stream can't be spliced safely. For anything that has to be properly gone, Redact PDF is the tool.
Common questions
How do I change text that is already printed in the PDF?
Switch to Edit text and every line the page can select turns clickable. Click one, retype it in the box that opens, and click away. The page repaints from the edited file and your change collapses into a marker you can click to revise it again. Scanned pages have nothing selectable in them at all, and a note above the toolbar says as much; run those through the OCR tool first.
There are no boxes to click into. Can I still fill this in?
Yes. A flat or scanned PDF has no fields for the tool to find, and it says so before you go hunting. Every toolbar mark works anywhere on the page, so Text goes on the line, Check goes in the box, Date drops a real date field and Cross handles the options you're declining. That is how most scanned forms get filled here.
Is a signature I add here a legal digital signature?
Not in the certificate sense. What lands on the page is a picture of your signature, which is an electronic signature, and that is what ordinary agreements and internal forms ask for. A digital signature in the strict sense is cryptographic: a certificate issued to you binds it, and a viewer verifies it. Nothing here issues or checks certificates.
Why does it say my form cannot be filled?
Almost always XFA. A few government and banking portals build their forms as dynamic XML instead of standard fields, the underlying library can't read that format, and the tool points you at Adobe Acrobat rather than pretending. Ordinary PDFs with no fields go down a different path: they load fine, and you mark them up with the toolbar.
The form has a signature box and it won't let me click into it.
Signature fields are left inert on purpose. One of those is a slot for a cryptographic signature, which nothing here can produce, so the control is drawn disabled with a note telling you to sign it in a PDF reader, and Fill & download skips over it. Use the Signature panel instead: draw or type your name, place it, then drag it across the box. The mark is painted onto the page and the empty field is left as it was.
It told me the file looks password-protected. What now?
Take it through Unlock PDF and bring the result back. Reading a form means parsing the document, and an encrypted one cannot be parsed until the password comes off, which is why the load stops before any field is found. You will need the password itself if the file demands one on opening.
I typed a name with an accent in it and got a warning after the download.
The font the PDF ships for that field has no glyph for the character, so the tool cannot draw a new appearance for the answer. It marks the document as needing appearances and leaves the drawing to your reader, which is why the fields arrive still editable and why flattening is off in that copy. Toolbar marks go down a separate path: a typed mark carrying a character its font cannot draw gets skipped, and the message says so.
Can I drop a photo of a rubber stamp onto the page?
Press Image on the toolbar and choose a PNG, JPEG or WebP. It previews in the panel first. A photographed stamp arrives with paper around it, so tick Remove background and the cut-out comes back with transparency behind the ink, or add Fill with colour and the picker beside it when a solid backing suits the page better. Place it, drag a corner to size it, and the rotate slider straightens a crooked scan.
What does the flatten checkbox actually change?
Whether your answers are still fields. Off, they arrive live and editable in the download. On, each one is drawn into the page and the field is deleted, so the copy renders identically in every reader and there is nothing left to click. Should a particular file refuse to flatten, you get told and the fields stay editable rather than the download quietly being wrong.
