Sign me Up does exactly one thing, and does it fast: drag your signature onto a PDF, resize and rotate it, export a clean signed copy. That's it.
Built because I needed to sign a PDF in five minutes flat, and every option I found was either a 400MB “office suite” in disguise, a subscription trap, or a website asking me to upload my contract to a server I'd never heard of. So I built the tool I actually wanted.
Otherwise, welcome. Drag your signature in, sign the thing, and go on with your day.
Sign me Up: PDF Signer collects no data. There is no account, no analytics, no tracking, no advertising identifier, and no server component.
Every document and signature image you open stays on your Mac. Files are read and written locally, at paths you choose. Nothing is uploaded, transmitted, or shared with the developer or any third party.
If you contact support by email, that email and its contents are used only to answer you, and are not shared with anyone else.
