Sign PDF

Add your signature to a PDF — draw or upload it, all in your browser.

How it works

  1. Select a PDF — it never leaves your device.
  2. Draw your signature on the pad, or upload a signature image.
  3. Choose the page, position and size for the signature.
  4. Click Sign — the signature is embedded locally and the signed PDF downloads.

Frequently asked questions

Is my document uploaded to sign it?
No. Signing happens entirely in your browser — your PDF and signature never leave your device.
Can I draw or upload my signature?
Both. Draw directly on the signature pad with a mouse or finger, or upload a transparent PNG/JPG of your signature.
Is the signature flattened into the PDF?
Yes — the signature is embedded as part of the chosen page, so it stays in place wherever the PDF is opened.
