Frequently asked questions about online signatures

Does an online signature have the same value as a handwritten signature?

Yes, provided you use a solution that complies with the European eIDAS regulation. Certyneo offers Simple (SES) and Advanced (AES) levels, both legally recognized in the 27 EU member states. Handwritten signatures and compliant electronic signatures carry the same probative force in court.

Do I need to create an account to sign a document online?

No. Only the person who SENDS the document for signature needs a Certyneo account (free). Signatories receive a simple link by email and sign in two clicks, without registration.

What document formats can I sign online?

PDF, Word (.docx), and most office formats. The system automatically converts them to PDF before signing to guarantee the integrity of the final document.

How much does online signature cost with Certyneo?

Free up to 5 envelopes per month, no credit card needed. Beyond that, the Standard plan at €19/month includes an entire team and unlimited envelopes (instead of per-user pricing like DocuSign or Yousign).

The signer receives a link by email. By clicking it, they open the document directly in their mobile browser — no app needed. They can draw their signature with their finger or click to sign if a pre-defined signature is associated with their email.
