Draw, Type or Upload — which should I use?

• Draw — most personal, looks like a real handwritten signature. Best on touchscreen or with a mouse. Use your finger on mobile.
• Type — clean and fast. Type your name and choose from several cursive signature-style fonts.
• Upload — use a scanned or photographed copy of your handwritten signature for the most authentic result.

Is a digital signature legally valid?

In most countries, a digital signature on a PDF is legally binding for everyday documents — contracts, consent forms, NDAs, employment agreements. The UK, EU (eIDAS) and US (ESIGN Act) all recognise electronic signatures as legally valid.

For documents requiring witnessed signatures or notarisation (wills, deeds, court documents), check your local regulations. For formal certified signatures, use eSign + Certificate which adds a timestamp and certificate block.

Does it work on iPhone and Android?

Yes — RightPDFKit is fully mobile responsive. On iPhone or Android, tap the signature area and draw with your finger. It works in Safari, Chrome and any modern mobile browser.

Is my PDF sent to a server?

No. The signature is applied entirely in your browser. Your PDF never leaves your device. This is especially important for sensitive documents like employment contracts, NDAs and legal agreements.
