AI Metadata Cleaner

AI Metadata Cleaner

AI Metadata Cleaner is a free in-browser metadata and AI provenance cleaner for images, video, PDF, and RAW files. It inspects and strips EXIF, GPS, XMP, IPTC, C2PA Content Credentials, and AI generator tags from Stable Diffusion, Midjourney, GPT-Image-2, and Veo 3. Processing runs locally in your browser via WebAssembly. There are zero file uploads, no signup, and no account. Pricing is 100% free.

The utility is built for AI artists, photographers, and privacy-conscious creators who need to see what a file is carrying before they share it. Camera EXIF, GPS location tags, XMP and IPTC blocks, Stable Diffusion and ComfyUI generation prompt chunks, and C2PA/JUMBF container markers are detected and removed on the device. Nothing is sent to a server.

Core capabilities

• Read-only provenance inspector, including the detect page, when you only want to look.
• Strip EXIF camera data and shooting parameters.
• Strip GPS location tags from photos and supported video.
• Remove XMP and IPTC blocks.
• Remove C2PA Content Credentials and JUMBF container markers.
• Remove AI generator tags associated with Stable Diffusion, ComfyUI, Midjourney, GPT-Image-2, and Veo 3.
• Local engines: LibRaw WebAssembly for Camera RAW, FFmpeg.wasm for video, and pdf-lib for PDF.
• Batch processing of up to 20 files with one-click ZIP export.
• Optional HTML5 Canvas re-encoding.

Supported file formats

Images: JPEG, PNG, WebP, AVIF, and HEIC. Video: MP4, MOV, and WebM. Documents: PDF. Camera RAW: DNG, CR2, NEF, and ARW, decoded with LibRaw WebAssembly.

For RAW files, use the Browser-Based Camera RAW (CR2, CR3, NEF, ARW, DNG) EXIF & MakerNotes Cleaner.

Honest boundary

AI Metadata Cleaner strips container-level metadata and C2PA/JUMBF markers. Pixel-domain SynthID watermarks are detected and explained. They are not removed, because they live in the image pixels rather than in the file container. Optional Canvas re-encoding still does not erase those pixel watermarks. The tool also does not guarantee how third-party social platforms apply their own AI labels after you upload a cleaned file.

Step-by-step workflow

1. Open https://aimetadatacleaner.pro/ in a current desktop browser. No account and no install are required.
2. Choose one or more local files. Images, video, PDF, and Camera RAW stay on your machine. The app does not upload them.
3. Inspect the report. Review EXIF, GPS, XMP, IPTC, C2PA Content Credentials, and AI generator tags before changing the file. A read-only inspector is at https://aimetadatacleaner.pro/detect.
4. Strip the container metadata you want removed: camera EXIF, GPS coordinates, XMP/IPTC, Stable Diffusion and ComfyUI prompt chunks, and C2PA/JUMBF markers.
5. If you are cleaning a Camera RAW file, the RAW cleaner uses LibRaw WebAssembly to read DNG, CR2, NEF, and ARW and clear EXIF and MakerNotes without a desktop raw converter.
6. Download the cleaned file. For several files, run a batch of up to 20 and export a ZIP.
7. Optionally re-encode an image through HTML5 Canvas when you want a fresh pixel buffer in addition to container stripping. Remember that this does not erase SynthID-style pixel watermarks.

FAQ

Does the file leave my browser? No. AI Metadata Cleaner is 100% client-side. Zero file uploads. Processing uses WebAssembly in the browser.

Is it free? Yes. It is 100% free, with no signup required, and it runs locally in the browser.

What does it remove? EXIF, GPS, XMP, IPTC, C2PA Content Credentials, JUMBF container markers, and AI generator tags from Stable Diffusion, Midjourney, GPT-Image-2, and Veo 3, plus ComfyUI prompt chunks.

What does it not remove? Invisible frequency-domain pixel watermarks such as Google SynthID. Those are detected and explained. Container metadata is what gets stripped.

Which formats are supported? JPEG, PNG, WebP, AVIF, HEIC, MP4, MOV, WebM, PDF, and Camera RAW (DNG, CR2, NEF, ARW via LibRaw WebAssembly).

Can I clean more than one file? Yes. Batch processing covers up to 20 files with one-click ZIP export.
