Add image stamps to your PDF using the annotation toolbar.
No — this tool adds a visible "wet-ink-like" e-signature image to the PDF, which is the standard way to sign contracts, NDAs, leases and most everyday paperwork. For cryptographic PKCS#7 signatures with a certificate (e.g. EU eIDAS qualified signatures), use our Digital Sign PDF tool instead.
In most jurisdictions (US ESIGN Act, EU eIDAS for simple electronic signatures, UK Electronic Communications Act) a visible signature plus clear intent is a valid electronic signature for everyday contracts. For highly regulated documents (real-estate transfers, court filings) consult your local rules — they may require a certificate-backed digital signature.
No. The signing happens locally in your browser using pdf-lib. Your unsigned PDF, the signature image and the signed output never leave your device, which is essential for confidential contracts.
Yes. Drag the signature onto any page, or use the "apply to every page" option to place it on all pages at once (useful for initialing every page of a multi-page contract).
Yes. The signature panel includes options to add a typed date stamp next to the signature and an optional initials field. You can also use our Edit PDF tool to add other custom text anywhere on the document.
