Sign PDF
Draw, type, or upload a visual signature and place it on selected PDF pages.
Add your signature to a PDF by drawing it with your mouse or finger, typing it in a script font, or uploading an image of a scanned signature - then place and resize it on any page. Good for signing a straightforward agreement, waiver, or form without printing, signing, and re-scanning. This produces a visual signature image, not a certificate-backed cryptographic signature, so it's not suited for documents that require legally verifiable digital signing. Everything is combined locally with pdf-lib.

Common questions
Is this a certified digital signature?
No. It adds a visual signature image or text. It does not create a certificate-backed cryptographic signature or audit trail.
Does my document leave the browser?
No. The PDF and signature are combined locally with pdf-lib.
Can I sign multiple pages in one document?
Yes - place your signature on as many selected pages as needed before saving.
Can I reuse the same signature later?
Draw, type, or upload the signature fresh each session - it isn't saved to an account since there's no server-side storage.
