Sign PDF

Sign PDF lets you put your signature on a document without printing, scanning or uploading it to a signing service. Draw on the signature pad with a mouse, finger or stylus — or type your name and have it rendered in a script style — then choose the page (first or last) and a bottom corner or center position. The signature is stamped onto a copy of the file, sized for a signature line, right in your browser.

Use a mouse, finger or stylus. If you draw anything, the drawing is used; otherwise the typed name below is rendered in a script style.

How to use Sign PDF

  1. Choose or drop the PDF.
  2. Draw your signature on the pad, or type your name in the box below it — the drawing wins if both are present.
  3. Choose which page to sign and where along the bottom it goes.
  4. Click Sign PDF and download the signed copy.

Supported behavior

  • A real drawing pad with stroke smoothing, plus Clear to start over as many times as you like.
  • Typed names render in a flowing script style with transparent background, like the drawn pad.
  • The stamp is placed at a standard signature size (about 57 mm wide) with its proportions intact.

Best for

  • Signing simple agreements, acknowledgements and permission forms.
  • Approving internal documents without a print–scan cycle.
  • Adding a signature to a form before flattening and sending it.

Limits

  • This is a visual signature — an image of your signature on the page. It is not a cryptographic digital signature: it does not certify identity or prove the document was not altered afterwards.
  • One signature on one page per run; run the tool again on the output to sign additional pages.
  • Whether a visual signature is accepted is up to the receiving party's policy, not this tool.

Privacy notes

  • Everything runs on your device: the document you open never leaves your browser.
  • Signatures are unusually sensitive — yours is drawn, stamped and saved entirely on your device, and no copy of it is kept anywhere by this page.

Sign PDF FAQ

Is this a legally binding digital signature?

It is a visual signature stamp. Many organizations accept those for everyday documents, but it is not a certificate-based digital signature and carries no identity verification. For regulated contracts, use a qualified signing service.

Drawn or typed — which should I use?

Drawn looks like your real signature and works with touch or a stylus. Typed is neater and consistent when a mouse-drawn scrawl would be illegible. Either is stamped the same way.

Can I sign every page?

The tool signs one chosen page (first or last) per run. Feed the signed output back in to add a signature to another page.

Where exactly does the signature land?

Along the bottom of the chosen page: right, center or left, with a small margin from the edges — where signature blocks conventionally sit. Fine positioning on a specific line is not offered.
