unmarking: a browser-based C2PA remover

Editorial interest 84/100 Selection signal · not a rating of the site

A free browser tool that removes C2PA content credentials from AI-generated images, video, and audio files.

Landing page captured for the 2026-09-05 issue.

Field notes

The page accepts a broad set of image, video, and audio formats, with a stated per-file limit of 256 MB. Its workflow is deliberately local: WebAssembly rewrites the file in the browser, and the resulting files can be downloaded individually or as a ZIP. The site distinguishes C2PA manifests from invisible watermarks such as SynthID, stating that only the former is removed while EXIF metadata and the underlying media remain unchanged.
