# Client-Side Forensic Metadata Inspection and C2PA Provenance Sanitization (Guide 15) Every image, video, and PDF exported from modern cameras or generative AI studios carries hidden binary containers—including EXIF GPS tags, XMP edit histories, JUMBF C2PA Content Credentials, and generator prompt chunks. Running a [Stable Diffusion ComfyUI and A1111 workflow metadata cleaner (63)](https://aimetadatacleaner.pro/stable-diffusion-metadata-cleaner) lets creators audit and strip these embedded headers locally in WebAssembly without uploading sensitive media to external servers. ## What Hidden Metadata Containers Reveal Before publishing visual assets or sharing documents with clients, teams can inspect and clean embedded records using specialized browser modules: 1. **AI Provenance & Generator Signatures**: Strip cryptographic JUMBF manifests and prompt parameters via the [Adobe Firefly C2PA Content Credentials metadata remover (63)](https://aimetadatacleaner.pro/firefly-metadata-cleaner), while keeping pixel data untouched. 2. **Camera EXIF, GPS & Document Properties**: Sanitize device serial numbers, coordinates, and author fields with the [Google Veo 3 MP4 C2PA provenance and container cleaner (63)](https://aimetadatacleaner.pro/veo-3-metadata-cleaner). 3. **Honest Forensic Verification**: Built-in before/after inspection clearly separates removable container metadata (EXIF, XMP, IPTC, C2PA, PNG `tEXt`/`iTXt`) from pixel-level statistical watermarks like Google SynthID. ## Zero-Upload Sanitization Workflow - **Step 1 — Local Binary Parse**: Drop up to 50 images, videos, PDFs, or RAW files into the browser inspector to view every embedded tag. - **Step 2 — Strip Container Chunks**: Execute instant in-memory byte-stream cleaning with zero recompression loss on supported formats. - **Step 3 — Verify & Download**: Confirm the post-clean forensic diff shows zero remaining EXIF/XMP/C2PA segments and export your clean files. ## Honest boundaries Container metadata (EXIF, GPS, XMP, IPTC, C2PA/JUMBF, Stable Diffusion text chunks) can be inspected and removed locally. Invisible frequency-domain marks such as Google SynthID are not removed. Social networks may still apply their own AI labels. Start with the [read-only C2PA and EXIF provenance inspector](https://aimetadatacleaner.pro/detect) before a destructive clean, then use the [local JPEG PNG WebP image metadata cleaner](https://aimetadatacleaner.pro/clean-image-metadata) or the [client-side MP4 MOV WebM metadata cleaner](https://aimetadatacleaner.pro/clean-video-metadata). ## FAQ **Are files uploaded?** No. Parsing stays in the browser via WASM where needed. **Does it remove SynthID?** No. **Batch?** Yes, with ZIP export.
