My stamp

Free + Pro What Pro adds here: keeping your stamp in your account, for your other devices.

Press your signature picture, logo and a line of text on a PDF, like a rubber stamp. In your browser, without uploading the file.

Open in the app The app opens with this tool already selected. Your PDF is not uploaded anywhere.

How it works

Prepare your stamp once: draw or type your signature, or add a PNG or JPEG picture, add your logo and a line of text. Then choose which pages get it (all, a range such as 1-3, 5 or 7-) and where.

The stamp is added as images and text on the pages. It is an image, not a digital signature: it has no certificate, does not prove who you are, does not detect later changes, and does not protect the document against them. For a signature with technical value use the Sign PDF tool with your certificate.

With the free plan, the stamp lives only while the page is open. With Pro, it is stored encrypted in your account and follows you to your other devices; it also displays your logo in the top bar.

What is not preserved, and limits

  • Images are redrawn without their hidden data and reduced to fit; the text line allows up to 120 characters.

Frequently asked questions

Is my signature stored anywhere?

With the free plan, only in the page's memory while it is open. With Pro, encrypted in your account. Documents are never uploaded: only the stamp is stored in your account.

Does it count as an electronic signature?

No. It is a stamped picture. To sign with a certificate use Sign PDF.

Can I stamp several documents?

Yes, the same stamp can be applied to the open document or to all those in the list (up to 3 at once on the free plan).

Why it is different

This tool works inside your browser. The file you choose stays on your device and is not sent to any server. That is why you do not need an account or an email to use it.
