How to sign a PDF online for free
Need to sign a contract, a form, or an agreement? No printer, no scanner - just open your PDF, place your signature, and download the signed document. Everything happens in your browser.
Why sign PDFs online?
Printing, signing by hand, scanning, and emailing back is slow, wasteful, and unnecessary. Online signing is faster and more practical.
- Save time. Sign and return a document in under a minute, instead of the print-sign-scan-email cycle.
- No printer needed. Works from any device with a browser - laptop, tablet, or phone.
- Keep it private. Your PDF and signature never leave your device. No cloud processing, no third-party access.

Is an online signature legally valid?
In most countries (EU eIDAS regulation, US ESIGN Act), a simple electronic signature - such as a drawn or typed signature on a PDF - is legally valid for everyday documents. It has the same legal standing as a handwritten signature for most non-regulated transactions. For high-stakes legal documents (real estate, notarial acts), a qualified electronic signature may be required.
