When to use Sign PDF

Best for

Use this when a document asks for a visible signature appearance rather than a certificate-backed cryptographic digital signature.

What the output changes

The PDF opens in FileCarpenter PDF Editor, where your typed, drawn or uploaded signature is staged on the page and written into the PDF only when you choose Done. The original file is not overwritten.

Check before sharing

This does not create a certificate-backed digital signature and does not prove signer identity or detect later document changes.

How Sign PDF works in FileCarpenter

Add a visible signature to a PDF. Type your name in one of several handwriting styles, draw it with a mouse, finger or stylus, or upload a signature image with its white background removed, then place, move and resize it on the page. Sign PDF uses the same signing engine as FileCarpenter PDF Editor.

Sign PDF is one of two editor-backed exceptions in PDF Tools: the file is handed to FileCarpenter’s own PDF Editor so the same signing engine is used everywhere on FileCarpenter. No account is required and your original file is never overwritten.

Good to know

Is this a legally binding digital signature?

No. This places a visible image of your signature on the page, which is what most everyday paperwork asks for. It is not a cryptographic digital signature and does not certify who signed or detect later changes.

Why does Sign PDF open the PDF Editor?

FileCarpenter uses one signing engine. The PDF Editor stages your signature on the page, lets you move and resize it, writes it into the PDF only when you choose Done, and validates the file before download. The PDF uses a temporary editing session that you can delete at any time.

Can I sign more than one page?

Yes. After placing the signature, choose Sign again on any other page. Your typed name and style are kept for the rest of the session.
