Sign PDF
Add your signature to a PDF — draw or upload it, all in your browser.
How it works
- Select a PDF — it never leaves your device.
- Draw your signature on the pad, or upload a signature image.
- Choose the page, position and size for the signature.
- 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.
