Sign PDF
Add a legally-usable signature to any PDF.
Draw, type or upload your signature and drop it onto the right page. Add initials, dates and typed name fields alongside it, then flatten the result so nobody can move it.
How it works
Four calm steps.
- 01
Drop your file
Drag the document you need to sign onto the upload card, or click to pick it from your device. You can also paste a link to a file hosted online.
- 02
Create your signature
Draw with a mouse or trackpad, type in a signature font, or upload an image of your existing signature.
- 03
Place and flatten
Position the signature, add date and initials if you want, then flatten so the signature becomes part of the page.
- 04
Download the result
Save the signed PDF to your device, share a temporary link, or send it straight to Google Drive or Dropbox. Files are wiped from our servers within one hour.
Why Sign PDF
Built to be the last sign pdf tool you try.
Use the mouse, a stylus on a tablet, or a photo of your ink signature.
Once you download, the signature is fused to the page – no one can drag it off.
Uploads travel over TLS, files are encrypted at rest, and every trace is deleted within 60 minutes. We do not read, index, or train on your documents.
The free tier handles most day-to-day work. You only create an account if you want history, larger files, or batch automation.
