How to sign a PDF

  1. 1Drop your PDF.
  2. 2Draw, type or photograph your signature. It goes where the form asks for one; drag it to move.
  3. 3Press Sign PDF, then download.

Three ways to make your signature

For a good photo: sign on plain white paper with a dark pen, a gel or felt-tip if you have one, then photograph it straight from above in daylight, filling most of the frame. If no ink can be found in the photo, the page says so and explains how to take a better one.

Choose Black or Blue ink. Blue is often preferred on Indian forms because it shows an original signature apart from a photocopy.

Where it goes

You often don’t have to place it at all. When the document asks for a signature, we find the place from its words: “Signature”, “Sign here”, “Signature of applicant”, “Authorised signatory”, “हस्ताक्षर” and similar labels, along with the line next to or above them. The signature starts there.

If a form asks in three places, a button says Sign all 3, and one tap signs every one.

If the document doesn’t say where, it starts at the bottom right of the last page, where most letters and agreements are signed. Many people just press Sign PDF at that point.

To move it, drag it. To make it bigger or smaller, drag its corner; it can’t go past the edge of the page. Tap any other page to put a signature there too, and remove any you don’t want.

Self-attested copies

Many Indian applications ask for “self-attested” copies: every page of your mark sheets, ID or certificates signed by you to confirm it’s a true copy. Turn on Sign every page (for self-attested copies) and the signature goes in the same spot on every page. Some offices also want the words “self-attested” written next to it. Ask them if you’re not sure.

Remembering your signature

Remember on this device is off unless you turn it on. When on, your signature is kept in this browser only, never on our servers, so next time it’s ready before you’ve done anything. Turning it off forgets it, and My Pocket shows what’s saved with a button to forget it. Leave it off on a shared or office computer.

Is it legally valid?

A signature added this way shows you agree to the document, and it’s accepted for most everyday paperwork: offer letters, rent agreements, school and society forms. It isn’t a certified digital signature. Some documents legally need one. In India, that includes some tax, company and court filings, which use a DSC or Aadhaar eSign. If you’re unsure, ask whoever will receive the document.

To fill a form before signing it, use Fill PDF form first. Its result has a Sign PDF button that brings the filled form straight here.

Common questions

Can I sign every page, like a self-attested copy?

Yes. Turn on "Sign every page" and your signature goes in the same spot on each page.

Can I use a photo of my signature on paper?

Yes. Choose "Photo" and pick or take the photo. We remove the paper background automatically, so only the ink lands on the page.

Is my signature saved?

Only if you turn on "Remember on this device". It is then kept in this browser alone, never uploaded, and one tap forgets it. Leave it off on shared or public computers.

Is a signature added this way legally valid?

It shows you agree, and it's accepted for many everyday documents such as offer letters, rental agreements and forms. It is not a certified digital signature. Documents that legally need one (in India, for example, some tax, company and court filings need a DSC or Aadhaar eSign) must be signed that way. If in doubt, ask whoever receives the document.
