What you can do
- Edit the text that's already thereClick a line of text and rewrite it. The original is covered in its own background colour and your text takes its place, in a matching size and family.
- Add text anywhereDrag a box, type, and set the font, size, weight, colour and alignment. Three families are embedded so the file opens the same everywhere.
- Sign itDraw a signature with your mouse or finger, type one, or upload a photo of the one you signed on paper, the background is lifted off for you, so only the ink lands on the page.
- Images and shapesPlace a PNG or JPG, or draw rectangles, ellipses, lines and arrows with control over thickness, fill and opacity.
- Annotate and white outHighlight, underline, strike through, draw freehand, or paint over anything you'd rather nobody read.
- Fill in formsDrop ticks, crosses and dots into checkboxes and type into any blank the form left you.
- Work on the pagesRotate, duplicate, delete and insert blank pages, and number the whole document in one go.
- Nothing is uploadedThe PDF is opened, edited and written again inside this tab. Turn your internet off after the page loads and it still works.

The thinking behind it
We wrote the guides first and built the tool because we kept needing it.
Questions
Is my file uploaded anywhere?
No. The PDF is read and rewritten entirely in your browser, there's no server involved and no copy is kept. Contracts, medical letters and bank statements stay on your machine.
Is it really free?
Yes. Every tool, any number of pages, no watermark and no account. It's genuinely free, not a trial.
Can I edit the text that's already in the PDF?
Yes, for most files. Pick the Text tool and click a line: it's covered in the page's own background colour and replaced with an editable box holding the same words at the same size. It works on ordinary text PDFs, not on scans, which are pictures of text rather than text.
What about scanned documents?
You can still white out, annotate, sign and add text on top of a scan. You just can't click the existing words to edit them, because there aren't any to click.
Can I upload a photo of my signature?
Yes. Sign a sheet of white paper, photograph it, and upload it under Sign → Upload image. You're offered three versions: the original, and two with the paper removed, one that keeps the original colours and a stronger one that also clears shadows and uneven lighting, which is usually the right pick for a phone photo. Pick whichever looks best and drop it on the page.
Does whiting something out really remove it?
It covers it. The original words stay in the file underneath and a determined reader could still pull them out with a text extractor, which is true of every editor that works this way, including the paid ones. Whiteout is right for tidying a document up; for genuinely secret information, print the finished PDF to a fresh PDF or to an image first.
Will my fonts match exactly?
New and edited text is set in Helvetica, Times or Courier, the families every PDF reader has built in, which keeps the file small and portable. A specialist typeface in the original won't be reproduced character for character.
Do form fields and links survive?
Yes, as long as you don't add, delete, duplicate or reorder pages. Those changes need the document to be rebuilt, which drops interactive fields. You'll see a note when that mode is on.
Can I open a password-protected PDF?
Yes, if you know the password. You'll be asked for it when the file opens. The password is used in your browser and isn't stored.
How large a file can I open?
Large ones are fine; pages are only drawn as you scroll to them. The practical limit is your device's memory, not the tool.
Is it safe to edit a PDF online?
It depends entirely on whether the tool uploads your file. Most free PDF sites work by sending the document to their server, which means a contract, payslip or ID scan lands on a machine you don't control, under a retention policy you didn't read. This editor never uploads: the PDF is opened and rewritten by JavaScript inside your own tab. You can verify that yourself by opening your browser's Network tab while you edit.
Do I need Adobe Acrobat to edit a PDF?
No. Acrobat Pro is the most capable PDF editor there is, and if you do heavy prepress or redaction work it earns its subscription. For rewriting a line, signing something, filling a form, whiting out a number or reordering pages, a browser is enough, and this one costs nothing.
How do I sign a PDF without printing and scanning it?
Open the PDF here, choose the signature tool, and draw it with a mouse or finger, type it, or drop in a photo of your signature on paper. Place it, resize it, and apply the changes. Nothing is printed and nothing is uploaded.
Does it work offline?
Yes, once the page has loaded. The editor is just code running in your tab, so you can disconnect and keep working. That's the practical test of whether a browser tool really is local.
The document stays on your device. Pages are rendered and written in your browser with pdf.js and pdf-lib, so the file you open is never uploaded, and the editor keeps working with the network off.
