Guides
Sign PDF adds your signature to a PDF right in your browser — draw it with your mouse, trackpad, or finger, or type your name in a signature-style font — then place it on the page you want and download the signed file. No signup, and nothing ever leaves your device.
How to use it
- Upload the PDF you want to sign.
- Choose Draw to sign with your mouse/trackpad/finger, or Type to render your name in a cursive-style font. Pick black or blue ink.
- Choose where the signature sits — one of the four corners, bottom-center, or dead center — and adjust its size with the slider.
- Enter a page number, or leave it blank to sign the last page (the common spot for a signature line).
- Press Sign PDF. The signed file downloads automatically as
signed.pdf.
Is this a legally binding electronic signature?
No — this is a visual signature: your drawn or typed mark is stamped onto the page as an image, the same way any free browser-based "sign a PDF" tool works. It's meant for everyday paperwork where a visible signature is enough (initialing a form, signing a draft for a colleague), not for documents that require a cryptographic, PKI-backed signature (PAdES/eIDAS-style) with an audit trail and identity verification. For that, you need a dedicated e-signature service with legal compliance built in.
Can I sign multiple pages?
Run the tool once per page — sign page 1, download it, then re-upload the signed PDF and sign page 2, and so on. Each pass only touches one page.
Will this work on a password-protected PDF?
A PDF with an owner lock but no open password usually signs fine. A file that requires a password just to open must be unlocked first — use the Unlock PDF tool, then sign the result.
Your file is processed entirely on your device and is never uploaded. To lock a filled-out form's existing values instead of adding a new mark, see Flatten PDF.
