How to Sign a PDF Free Online — No Adobe, No Account (2026)

In 2026, you can sign any PDF directly in a browser in under 2 minutes, for free, without Adobe Acrobat, without an account, and without printing a single page.

Electronic signature vs digital signature — what is the difference?

An electronic signature is any mark applied digitally to indicate agreement — a typed name, a drawn signature, or an image of your handwritten signature. It is legally valid for most everyday contracts, NDAs, employment agreements, and commercial documents in most countries (EU eIDAS regulation, US ESIGN Act). A digital signature is a cryptographic certificate-based signature (like DocuSign or Adobe Sign) that provides additional tamper-evidence and identity verification. For internal documents, freelance contracts, and everyday agreements, a free electronic signature is fully sufficient. For legally critical documents requiring a certified audit trail (property transactions, court filings), use a platform with certificate-based signatures.

Frequently Asked Questions

Is a free electronic signature legally binding?+

Yes in most cases. Electronic signatures are legally valid under the US ESIGN Act (2000), EU eIDAS Regulation, and equivalent laws in the UK, Canada, Australia, and most countries. For property deeds, wills, and court documents, check local requirements.

Can I sign a PDF without printing it?+

Yes — that is the entire point. Upload the PDF, apply your signature digitally, download. No printer, no scanner, no paper needed.

How do I create my signature?+

Draw it using your mouse, trackpad, or finger on a touchscreen. Type your name in a signature font. Or upload a photo/scan of your handwritten signature as a PNG image.

Can I sign in a specific position on the page?+

Yes. In AI Studio, specify: "sign at the bottom right of page 2" or "place my signature below the date field on the last page".

Can I request someone else's signature on my PDF?+

For requesting signatures from others (multi-party signing), use a dedicated e-signature platform. EditDocs AI handles single-signer scenarios where you are signing your own document.
