No Acrobat, No Install, No Account
You don't need a paid Acrobat licence or any software to sign a PDF. This tool runs in the browser: draw with a mouse or finger, type your name in a script style, or upload a scan of your signature, then place it on the page and download.
Everything Stays on Your Device
Unlike desktop or cloud signers, nothing is installed and nothing is uploaded — the signed file is assembled locally, which keeps private paperwork private and works the same on any operating system.
