# StripC2PA

> StripC2PA scans and removes C2PA Content Credentials, EXIF, XMP, IPTC and AI-generation metadata from JPEG, PNG, WebP, MP4 and MOV files, and from ZIP archives of them. Files are processed in memory at the edge (Cloudflare Workers) and never stored. Pixel data and video frames are not re-encoded.
