A signature you can reuse
Draw it with a finger, type it in a handwriting face, or photograph one off paper and we drop out the background. Save it once and it is there next time.
Free to fill · no sign-up
Fill in and sign any PDF on your phone.
Type anywhere on the page, tick the boxes, add the date and a signature you'd actually put your name to. Then save it as a PDF or a Word document.
- Works properly on a phone, not just a laptop
- A proper signature — drawn, typed or photographed — not a mouse scribble
- Your file never leaves your browser

3 free saves every 30 days, each with a small footer line. Pro is £6 a month and removes both. See pricing.
Edge, Chrome and Preview already do some of this — free
If all you need is to type a line onto a PDF, your browser can do it and we'd never charge you for that. We wrote the guides for those tools too. PDFpad exists for the part where they stop.
A finished document, not a form
Everything you add is drawn into the page on save and any existing form fields are flattened, so nobody can drag your answers around or delete them.
Word export
Save the completed document as a .docx with one page image per PDF page, so it opens in Word, Pages or Google Docs without reflowing.
Dates, ticks and crosses
Proper field types instead of a text box you nudge into place — a tick that sits in the box and a date in the format the form wants.
Built for a phone
Pinch to zoom, a thumb-sized toolbar, and a signature that looks like your signature because you drew it with a finger, not a trackpad.
Nothing uploaded
The document is opened and written in the browser. Our server only ever learns how many pages it has and a fingerprint used to count your free saves.

Questions
- Is my file uploaded to your server?
- No. PDFpad opens and edits the document in your browser using JavaScript. The only things our server ever sees are the page count, the file size and a SHA-256 fingerprint used to count exports — never the document itself.
- Can I fill in a PDF that has no form fields?
- Yes. That is the normal case. You click anywhere on the page and type; PDFpad draws the text onto the page when you save. If the PDF does have proper form fields, PDFpad finds them and you can click straight into them.
- What does it cost?
- Filling in and signing is free and unlimited. Saving is free for 3 exports every 30 days, each with a small "Filled with PDFpad" line in the footer. Pro is £6 a month or £39 a year and removes both the limit and the line, and adds Word export. You can also unlock a single document for £2.
- Is a signature made in PDFpad legally binding?
- A signature you draw, type or upload here is an electronic signature, which is accepted for most everyday agreements in the UK, EU and US. It is not an advanced or qualified electronic signature, and it carries no audit trail or identity check. For documents that need those, use a service built for them.
- Does it work on an iPhone or Android phone?
- Yes — that is the point of it. The page is built for a phone browser first, and signing with a finger on a touchscreen looks like a real signature rather than a mouse scrawl.
- Can the person I send it to edit what I filled in?
- No. When you save, your text, ticks and signature are drawn into the page itself and any existing form fields are flattened, so the recipient sees a finished document rather than a form they can change.
