AI Metadata Cleaner inspects and removes hidden metadata from images (JPEG, PNG, WebP, AVIF, HEIC), camera RAW (DNG, CR2, NEF, ARW via LibRaw WASM), videos (MP4, MOV, WebM via FFmpeg.wasm), and PDFs (pdf-lib) entirely in the browser. It strips EXIF, GPS, XMP/IPTC, Stable Diffusion and ComfyUI prompt chunks, and C2PA/JUMBF markers. Includes a read-only /detect inspector and batch ZIP export. It does not remove invisible pixel watermarks such as Google SynthID, and it does not control how social platforms label AI content.
