Add your signature to a PDF online for free. Draw or type your signature and place it anywhere on the document. Stays 100% on your device.

Stays in your browser

Processing runs on your own device. Your files are not uploaded to a server, so private documents stay private.

Draw or type your signature, place it anywhere on the document and download the signed PDF. It adds a visual signature to the page, not a certificate-based digital signature with cryptographic verification, so contracts that need a legally binding e-signature with an audit trail may require a dedicated e-signature service. Whether a signature is valid depends on your local laws and the document.

Good to know

  • Use a consistent signature style across documents so it's recognizable as genuinely yours.
  • Position the signature clearly within the designated signature block to avoid ambiguity.
  • Keep a signed copy for your own records immediately after signing, before sending it onward.
  • This adds a visual signature image/drawing to the page — it isn't a certificate-based digital signature with cryptographic verification.
  • For contracts requiring legally binding e-signatures with an audit trail, a dedicated e-signature service may be required by your jurisdiction or counterparty.
  • Doesn't verify the signer's identity — it simply places the signature you provide onto the document.

Troubleshooting

  • The signature only appears on one page: The tool places your signature on the page you're currently viewing in the preview. Navigate to each page that needs a signature and sign it separately.
  • The signature is in the wrong spot: Click the exact spot on the page preview where you want the signature before saving — the last spot you clicked is where it will be placed.
  • "Please draw or type your signature first": You need to either draw in the signature pad or type your name to generate a signature image before signing the page.
  • "Signing failed": The source PDF may be corrupted or use features the tool can't handle. Try Repair PDF on the original first.
