Signing a document should not mean printing it, signing it by hand, and scanning it back. With this free sign PDF tool, you can add your signature to a PDF entirely in your browser: draw it with a mouse, trackpad or finger, type your name in a handwriting style, or upload a signature image you already have, then choose the page and position and download the signed file. It is made for everyday signing jobs like contracts, offer letters, consent forms, invoices and school forms, where the signature usually goes on the last page, bottom-right, but sometimes needs to be on a specific page instead. Because the signature is placed as an image on the page you choose, you control exactly where it lands and how large it is. Everything runs in your browser with pdf-lib, so your document and signature are never uploaded. One honest limit matters: this adds a visible signature image, not a certified cryptographic digital signature, so check the requirements for formal documents first.

Frequently asked questions
No. This places a visible signature image on the page you choose. It does not use a certificate and does not cryptographically verify your identity, so check whether the recipient accepts a visible signature for formal documents.
