Can you sign directly in PowerPoint?

PowerPoint allows you to insert a signature image, but this does not constitute an enforceable eIDAS electronic signature. For legal value, export the presentation as a PDF and then sign it on a dedicated platform.

Do you need to install software?

No. You simply export your presentation as a PDF, then sign it online from your browser.

Are all slides preserved?

Yes, each slide becomes a page of the PDF, with its formatting, images and graphics intact.

Can multiple people sign the presentation?

Yes, you can invite multiple signatories and define the order in which they sign.

Does the signed presentation remain editable?

No. Once signed, the PDF is sealed: any subsequent modification would invalidate the signature and its integrity.

Legal value & compatibility

A PowerPoint presentation can be electronically signed with full legal value. You do not sign within PowerPoint itself: you export the presentation to PDF, then apply the signature to this PDF via a compliant platform. The signature is recognized throughout the European Union under the eIDAS regulation.

To move from theory to practice, discover the Certyneo electronic signature solution and its offer dedicated to your sector — eIDAS compliant, no installation required.

Electronic signature has the same value as a handwritten signature (article 25 of the eIDAS regulation).
PowerPoint does not offer native eIDAS electronic signature: you go through an exported PDF signed online.
Each signature is timestamped and sealed, which guarantees the integrity of the presentation after signing.
A proof file (signer identity, date, file fingerprint) is kept and can be produced as evidence in case of dispute.

Frequent use cases

Commercial proposals and pitches presented to a client.

Training materials to be signed off by participants.

Illustrated specifications to be validated by a service provider.

Project presentations requiring approval from a committee.

Partnership brochures to be countersigned by both parties.

Progress reports or assessments presented to management for approval.
