Sign PDF

How to put your signature on a PDF

1. Choose the PDF (or drop it on the box).
2. Make your signature, one of three ways:
   • Draw: sign on the pad with a finger, a stylus or the mouse, in black or blue. The line is smoothed and gets thinner where you move fast, as a pen does. Undo a stroke, or clear and start again.
   • Type: your name in a handwriting font: Dancing Script, Great Vibes, Pacifico, or Lakki Reddy for a name in Telugu. Each shows your name, so you can pick.
   • Photo: sign on plain white paper, take a photo, and the paper is cleaned away, leaving the ink alone on a clear background, cut close round it. Turn it if it is sideways; drag the corners if the box takes in more than the signature.
3. Tap the page where it goes; on a signature line it sits on the line. Drag it, or the dot at its corner to resize it. Add the date (12/08/2026 as dd/mm/yyyy, or another format), your name, or any text the same way.
4. For your initials on every page: make your initials, place them on one page, then tap Initials on every page. They go to the same spot on each page, from the right or bottom edge when they are on that side, so they land right on landscape pages too.
5. Tap Save the signed PDF, then download or share it, such as agreement-signed.pdf.

Everything happens in your browser: your signature and your PDF are never uploaded to ap7am or anywhere else. The PDF’s own text and pages stay as they were; the signature is drawn on top, where you put it.

What this signature is, in law

A signature added here is a picture of your signature, as if you had signed on paper and scanned it. It is not a digital signature certificate (DSC) and not an Aadhaar eSign, which are electronic signatures recognised under the Information Technology Act, 2000. Where a form, a portal or a filing asks for a DSC or an Aadhaar eSign (company and tax filings, some tenders and government portals), use that: a picture of a signature does not take its place. Where a form only asks for your signature on the page, check what it says it accepts.

What is kept on your device

Nothing, unless you tick Remember my signature on this device. Then your signature (and initials) are kept in this browser’s own storage on this phone or computer, so they are ready next time; they are never sent anywhere. Untick it, or tap Forget my signature, to remove them. On a shared or office computer, leave it off.
