Sign a PDF without printing it
The old way is print, sign, scan, and the scan comes out crooked. Drop a picture of your signature onto the page instead, move it to the line, and save.

How it works

Questions
Do my files get uploaded?
No. This tool runs in your browser with JavaScript, so the file never leaves your device. Once the page has loaded you can even go offline and it still works.
Is there a watermark or a sign-up?
← All 24 PDF tools
Neither. No account, no watermark on the output. The practical limit is your device memory — large scanned files use more of it.
