OfficeBoy by PaperBoy

Sign a PDF online

Draw your signature with a finger or a mouse, type it, or upload a photo of it, then tap where it goes. If the page has a signature line, OfficeBoy offers to put it there. You can add the date and your name the same way.

This adds a picture of your signature to the PDF. It is not a certificate-based (qualified) digital signature. Ask whoever receives the document which kind they need.

Questions people ask

Is it free?

Yes. There is no account and no limit on how many documents you sign.

Is my signature stored somewhere?

Only if you choose to remember it, and then only in this browser on your device. You can remove it there at any time.

Is a signature like this legally valid?

That depends on the document and on who receives it. Many everyday documents are accepted with a drawn signature. Where the law or the receiver asks for a qualified electronic signature, this is not one.

Can I sign on a phone?

Yes. Drawing with a finger works well, and the signature can be made larger or smaller after it is placed.

Can I sign on my phone when the document is open on my computer?

Yes. Choose On your phone in the signature window and scan the QR code. You sign with your finger and the signature appears on the computer. Only the picture of the signature travels between the two, locked so that our server cannot see it; the document stays on the computer.
