How it works

From PDF to sealed signature in three steps

No accounts for your signers, no apps, no certificates to install.

  1. 1. Upload

    Drop one or more PDF documents (or images). We compute their SHA-256 fingerprint instantly.

  2. 2. Send

    Enter each signer's first name, last name and email. They receive a unique, secure link.

  3. 3. Signed and sealed

    They sign with a finger or mouse. We close the document with a hash and a qualified timestamp.

Product

Everything you need to sign with confidence

A simple experience for you and your signers, with the evidentiary strength a contract demands.

Biometric signature

We capture the stroke with pressure, speed, acceleration and timing, plus contextual evidence.

Qualified timestamp

Every document is sealed with an RFC 3161 timestamp issued by a European qualified provider.

Evidence certificate

A detailed report with signers, devices, fingerprints and the timeline of the whole process.

Public verification

Anyone can check a document's integrity with its code or by uploading the PDF.

Multiple documents and signers

Up to 10 documents and 10 signers per envelope, in parallel or in the order you choose.

Automatic reminders

We remind your signers about pending documents and keep you posted at every step.

Legal validity

Advanced electronic signature under the eIDAS Regulation

Regulation (EU) 910/2014 (eIDAS) gives legal effect to electronic signatures and defines the advanced electronic signature in its Article 26. This is how DocuFirma meets it:

DocuFirma provides advanced electronic signatures, not qualified electronic signatures.

Read the signature policy

  • Uniquely linked to the signer

    Each signer receives a unique, personal link by email and signs with their own stroke.

  • Capable of identifying them

    We record name, email, IP address, device and the biometric data of the signature.

  • Under their sole control

    The signer creates the signature by hand, on their own device, after reading the document.

  • Detects any change

    The SHA-256 fingerprint and the qualified timestamp (Art. 42) reveal any subsequent modification.
