Why people sign with QuickSigner

AATL-certified signatures

Every document is signed using the PAdES standard and backed by the Adobe Approved Trust List — recognized signing technology, not just an image on a page.

Legally binding in US, UK & EU

Valid under ESIGN/UETA in the US, eIDAS across all EU member states, and UK law — with a verifiable audit trail on every document.

Tamper-proof & ISO 27001

Every signed document is sealed with a digital certificate and a full audit trail — once signed, it can't be altered.

Affordable, free to start

A genuinely free plan for occasional use, then plans from just $5/user/month — a fraction of what the big names charge.
