Need to sign a form or agreement but don't want to print it, sign with a pen and scan it back? You can add your signature to a PDF right on screen — draw it, type your name in a handwriting style, or upload a photo of your real signature — then place it exactly where it belongs and download the signed file. It's free, with no signup, and it works on a phone too.

The quick way

  1. Open the free Sign PDF tool.
  2. Choose your PDF.
  3. Create your signature: draw with a mouse or finger, type your name, or upload a photo of your signature. Pick an ink colour if you like.
  4. Tap the page where it should go, then drag it into position and resize it.
  5. Download the signed PDF.

Upload a photo of your real signature

If you want your actual signature, sign on white paper, take a clear photo, and choose Upload. The white background is removed automatically so only the ink sits on the page. You can even recolour it — a scanned black signature can be turned blue.

Is this a legally valid digital signature?

It adds a visible signature to the page — the same as signing a printed copy by hand. It is not a certificate-based digital signature (DSC) or Aadhaar eSign, which cryptographically prove who signed. If a filing specifically requires a DSC or eSign, use that provider. For everyday forms and agreements, a placed signature is what people use.

Add a stamp or seal too

Need a company stamp or seal as well? Sign PDF & Stamp has its own Stamp button: upload the stamp once and place it on any page, next to your signature. It works on JPG and PNG images too.
