Sign PDF

Draw your signature, type it in a handwriting font, or upload a photo of it (the paper background is removed). Then click where it should go, drag to move and resize, and save.

It places an image of your signature on the page - the same as signing a printout and scanning it. It is not a certificate-based digital signature, which needs a signing certificate.

Sign PDF puts an image of your handwritten signature on the page: it looks like a signed and scanned printout, and it is enough where a signature only has to be seen - an internal form, a delivery note, a letter. Anyone could copy that image, so it proves neither who signed nor that the document hasn't changed since. Digitally Sign PDF signs the file with a certificate: a PDF reader shows who signed and warns if anything changed afterwards. Use it where it matters who signed and that nothing changed since - a contract, an invoice, an official submission - and you have a certificate (.p12 / .pfx). The two go together too: the digital signature can carry your handwritten signature as its visible appearance.

Nothing is uploaded: the file is opened and processed inside your browser and never leaves your device. Close the tab and it is gone. The signature stays in your browser too.

Yes. Build as many as you need - two signers, or a full signature and a set of initials for the other pages - and click to drop whichever one is active. The rail shows each with a count of how many times it has been placed.

With a Pro account, yes: save it to your account and it is there the next time you open the tool. That is the one thing we keep on our side, it happens only when you press the button, and it is the signature image alone - never the document.

Yes. Drop in a .docx, .xlsx or .pptx file or an image (JPG, PNG, WebP...) and it is turned into a PDF in your browser as it arrives - an image onto an A4 page - then handled like any other PDF; nothing is uploaded. The conversion is our own, so the result can differ slightly from Office's own PDF export: a font may be substituted and charts are left out. The file list shows a warning when something couldn't be carried over.
