What is the PDF Sign tool?

Is an electronic signature legally valid?

In most countries, an electronic signature is legally equivalent to a handwritten one for the majority of everyday documents. In the United States, the ESIGN Act and UETA make most e-signatures legally binding. The EU recognises qualified and advanced electronic signatures under eIDAS. For contracts that require a notarised signature, a witnessed handwritten signature, or a seal — such as real estate deeds or court filings — a simple electronic signature may not be sufficient. When in doubt, consult a legal professional about the requirements for your specific document type.

Tips for a professional and secure signature

• Draw on a touchscreen for natural results. A finger or stylus on a phone or tablet produces a more organic-looking signature than a mouse on a desktop.
• Upload a photo of your real signature. Sign a blank piece of paper in black ink, photograph it against a white background, and upload the image. This gives the most authentic result.
• Place the signature precisely. Zoom in to the signature field before placing to avoid signing over other text or outside the designated area.
• Add the date next to your signature. For most contracts, a typed date field placed next to the signature adds important context without additional tools.

Frequently asked questions about signing PDFs

Can multiple people sign the same PDF?

Yes. PDF me supports multi-signer workflows — you can invite other signers by link so everyone can add their signature to the same document without emailing it back and forth.

Does the signed PDF include a digital certificate?

PDF me produces a standard visual signature embedded in the PDF. For documents that require a cryptographic certificate (qualified electronic signatures under eIDAS), you would need a dedicated certified signing authority.

Can I sign a PDF on my phone?

Yes. The Sign PDF tool is fully optimised for mobile browsers. Draw your signature directly on the touchscreen for the best result.
