Why Truepic?

As a co-founder of the Coalition for Content Provenance and Authenticity (C2PA) open technical standard, our signing toolkit stands out as the pioneering commercial solution, supported by unparalleled industry expertise.

Fast and easy integration

Integrate C2PA without disruption, harmonizing with your team’s tech stack, roadmap, and needs.

Unrivaled security

Benefit from enterprise-grade security and key management features out of the box for the safest signing possible.

Authentic implementation

Harness our trusted implementations to seamlessly sign media upon capture or AI generation, enabling you to preserve the authenticity of digital content.

What is the C2PA?

An open technical standard providing publishers, creators, and consumers the ability to transparently trace the origin and history of different types of media. The implementation of the standard utilizes PKI to cryptographically bind data to a file in a tamper-evident way.

PlatformsWhere it works


Seamlessly incorporate signing with Truepic certificates into your server and cloud-based media workflows via command line integration. With the Truepic CLI, effortlessly enroll, sign, and verify media directly within your application using a straightforward command.


Easily sign any content directly on mobile devices using our native SDKs for iOS and Android made by developers for developers. Whether it’s user-generated, filtered, or uploaded media, signing occurs on the device without compromising privacy, thanks to automatic daily key and certificate rotation.


Our C2PA library can also be integrated directly into smartphone and camera hardware such as chipsets to ensure that the original details of the media are verified and cryptographically sealed upon creation.
