How to use Sign PDF

Upload a PDF and select the page to sign.
Type your name and choose a font and colour, or upload a PNG/JPEG signature.
Choose Add signature, then click or tap on the PDF at the desired location. Repeat for additional signatures.
Download your signed PDF and review it before sharing.

What kind of signature does this add?

This adds a visible signature image, not a certificate-based digital signature or identity verification. Editing an already digitally signed PDF may invalidate its existing signatures.

Are my documents uploaded?

No. PDFs and signature images are processed locally in your browser. Fonts are included with this website, with no external font service. Refreshing clears the workspace.

Can I resize a signature photo?

Yes. The slider resizes either kind of signature while preserving proportions and keeping it inside the page. Select a signature and choose Move / resize to adjust it with the mouse or the size slider. Choose Lock position when finished.
