How DocuFirma works

A process designed to make signing as easy as opening an email, without giving up legal guarantees.

For the sender

  1. 1

    Create your account and upload one or more PDFs, images or Word documents.

  2. 2

    Add the signers with first name, last name and email. Choose whether they sign in parallel or in order.

  3. 3

    Track every envelope in real time and receive the signed PDF, the evidence certificate and the timestamp.

For the signer

  1. 1

    Opens the link in the email: no account, nothing to install.

  2. 2

    Reviews the full document in the browser, on a phone or a computer.

  3. 3

    Accepts the consent and signs on screen. Gets a signed copy instantly.

What happens behind the scenes

  • We compute the SHA-256 fingerprint of every original document.

  • We capture the biometric stroke and store it encrypted with AES-256-GCM.

  • We generate the signed PDF with the signature, the verification code and an evidence certificate.

  • We request an RFC 3161 qualified timestamp over the final document.

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.
