Anleitung

Upload Contract PDF: Drop the PDF contract in. The tool accepts any PDF: standard contracts, multi-page agreements, scanned contracts. We process 1-100 page documents without issues.
Place Signature: Click on the signature line position to add a signature box. Drag it to the right spot on the page. Resize if needed. Add date, initials, name, or title as separate text fields if required.
Sign (Type or Draw): Three signing modes: type your name (rendered in 5+ signature-style fonts), draw with mouse/touch on a canvas, or upload a scan of your handwritten signature. All three are saved locally and embedded in the PDF.
Save Signed PDF: Click 'Save'. The signed PDF is downloaded with the signature burned into the page. Email it to the counterparty. Optional: add password protection via PDF Encrypt before sending confidential contracts.

Häufige Fragen

Can I sign a contract PDF without uploading it?

Yes — our PDF Sign tool runs entirely in your browser. Drop your contract, place a signature, type/draw/upload your signature, save. The signed PDF is created locally via pdf-lib. No upload, no DocuSign account, no third-party storage.

Is an electronic signature legally binding?

In most jurisdictions (US, EU, UK, Canada, Australia, etc.), yes — under eIDAS in the EU and the E-SIGN Act in the US. Our signatures meet basic requirements: signer attribution, intent to sign, document integrity. For high-stakes agreements (real estate, certain regulated industries), consult a lawyer about additional requirements.

What's the difference between typed, drawn, and uploaded signatures?

Typed: type your name and we render it in a cursive-style font. Visually clean and easy to edit. Drawn: use mouse/finger/touch to draw your signature on a canvas. Most authentic-looking. Uploaded: scan your handwritten signature once (use a signature pad, paper scan, or photo) and reuse it across all future documents. All three are equally legally binding in most jurisdictions.

Can I save my signature for reuse?

Yes — once you create a signature (drawn or uploaded), our tool offers to save it to browser localStorage. Next time you sign a PDF, just pick your saved signature from the list. Stored only on your device, never sent anywhere.

Will the signed PDF look like the original?

Yes — our tool embeds the signature on top of the original PDF without modifying any other content. The signature appears at the position you placed it, with the size you chose. Background watermark-free, formatting unchanged, ready for email or printing.

Can I add multiple signatures to one contract?

Yes — drop multiple signature boxes. Useful for two-party agreements, multi-page contracts with initialled pages, or counter-signed documents. Each signature can be from a different person with their own signature style.
