Sign PDF

How sign pdf works

1. Choose a plain PDF and draw a signature with your mouse, pen or finger.
2. Select a page and signature size.
3. Add the signature image, then inspect the downloaded PDF before sending it.

This is a signature image, not identity verification

The tool embeds a visible image of your drawing. It does not verify identity, prove consent, apply a cryptographic certificate, protect the PDF from later edits, or manage a signing request. Check whether the recipient requires a particular signature method.

Supported files

One plain, unsigned PDF up to 20 MB and 200 pages. Password-protected files, existing signatures, interactive forms, attachments and active content are not supported. Your PDF and drawn signature are processed in your browser and are not uploaded.
