Sign a PDF

Draw your signature with a finger or a mouse, place it where it belongs and fill in the blanks. Everything happens on your device.

⚖️ This is not a digital certificate. It places a picture of your signature into the document — the same as printing, signing and scanning, but without the printer. Nothing here proves who signed or stops the file being changed afterwards.

What this tool does

Sign a PDF
Places a drawn or uploaded signature at a spot you pick on the page. It is a visual mark, not a cryptographic signature — it does not prove who signed, and a court will not treat it as a qualified electronic signature.

When you need this

  • A rental agreement arrives by email and should be signed without printing it.
  • A parent consent form has to be returned today, and there is no printer at home.

Frequently asked questions

What files can I use here?

Reads PDF. One file at a time.

What do I get back?

You get PDF.

Does the file lose quality?

The pixels and the text are left alone. Only the structure around them changes.

When does it not work?

Password-protected files cannot be opened. This adds a visible signature mark; it is not a cryptographic or qualified electronic signature.

Does the text stay searchable?

Yes, and compressing keeps it that way too: by default only the embedded photos are recompressed, while text, fonts and layout stay untouched. Merging, splitting and adding images move the pages as they are. Only the second compression method redraws every page as an image — then the text becomes part of the picture, and the tool says so before you start.

Can password-protected PDFs be opened?

No. A PDF locked with a password cannot be read in the browser, and the tool says so rather than producing an empty document. Remove the protection in the program that created the file first.
