What this tool does
Puts your signature on a page as a visible mark. You either draw it in the box with a mouse, trackpad or finger, or upload an image of a signature you already have, then drag it to the right spot on the page. This is the digital equivalent of signing on paper: it is not a cryptographic or qualified electronic signature, so it carries no certificate and says nothing about who signed. The document never leaves your browser.
How to use it
- Drop the PDF and choose whether to draw the signature or upload an image.
- Draw it in the box — Clear starts over — or pick a JPG or PNG; a transparent PNG looks best.
- Step to the page you want to sign, drag the signature where it belongs, and drag a corner to resize it.
- Download the signed file.
Common questions
- Is this a qualified electronic signature?
- No. This tool places a picture of a signature on the page, nothing more. There is no certificate behind it, so it does not prove who signed and it does not show whether the file was altered afterwards. Wherever a qualified electronic signature is legally required, this is not a substitute for it.
- Can I sign more than one page?
- One run signs the page you have open. To sign another page, drop the downloaded file back in and place the signature again.
- The signature looks stretched. What happened?
- It should not: the box keeps the signature's own proportions while you resize it. If the shape is off, it usually comes from the uploaded image — crop the picture close around the signature and try again.
