Add Your Signature

什么是 Add Your Signature？

Add Your Signature is a free PDF signing tool that runs entirely in your browser. Unlike Smallpdf, iLovePDF, DocuSign and Adobe Acrobat online, which all upload your file to their servers before you can sign it, this one keeps the PDF on your device the whole time. Just drop in a file, draw or upload your signature, place it on any page, and download the signed PDF. No account, no email, no watermark, no page limit, and it works just as well on a phone as on a desktop.
