c2pagen

c2pagen is a CLI for bulk generating reproducible C2PA assets for testing and benchmarking C2PA tooling. Assets are generated from configurable presets spanning a range of formats, sizes, and manifest complexities.

Supported Formats

• Image: JPEG, PNG, GIF, TIFF, SVG
• Audio: WAV, MP3
• Video: MP4

Please create an issue if you'd like to see another format or preset supported.

Usage

List available presets, optionally filtered by tag:
