AI Info Tag Checker
for Images & Videos

See exactly what hidden metadata is embedded in your image or video — AI tags, C2PA content credentials, GPS, editing software, and more. The check runs entirely in your browser. Nothing is uploaded.

What we check for

  • AI tags — markers from ChatGPT, DALL·E, MidJourney, Stable Diffusion, Adobe Firefly, Runway, Microsoft Designer.
  • C2PA content credentials — the cryptographically signed metadata that Adobe, OpenAI, and Microsoft embed to identify AI-generated or AI-edited media.
  • EXIF camera data — make, model, ISO, aperture, exposure, lens.
  • GPS coordinates — phones embed your exact location by default.
  • Editing software — what app modified the file (Photoshop, Premiere, CapCut, etc.).
  • Embedded thumbnails — small preview images that may not reflect crops you made.

Why check before cleaning?

So you can trust the cleaner. Drop a file, see what’s in it, then run the cleaner on the same file and verify the new file shows nothing. That round-trip is the most honest demo we can offer — no marketing, no “trust us.”

What this check can’t see

Pixel-level watermarks (SynthID, baked-in branding) don’t show up here — they live in the pixels, not in metadata. Platform-side perceptual hashes and content fingerprints are also out of scope. This tool inspects file metadata only.

// common questions

Frequently asked.

Does the file leave my device?+

No. We read the file in your browser via the FileReader API and parse the metadata locally. Open dev tools, watch the Network tab while you drop a file — you'll see zero requests. Disconnect from the internet after the page loads and it still works.

Why does my AI-generated image show 'No C2PA' even though I made it with ChatGPT?+

Some AI tools sign their outputs, others don't. ChatGPT/DALL·E have signed since 2024, but if you took a screenshot of the result or re-saved it through a tool that stripped metadata, the C2PA tag may already be gone. The checker is honest about what's in the file *right now*.

How does C2PA detection work without parsing the full manifest?+

We scan the file for the C2PA UUID marker (in video uuid boxes) and for JUMBF magic bytes + 'c2pa.' label strings (in JPEG/PNG). That's enough to detect presence reliably. For full claim parsing (which AI tool, when, what edits) you'd need a heavier library — we keep this checker lightweight.

Can it check RAW camera files?+

Not currently. RAW formats (CR2, NEF, DNG, ARW) can't be decoded by browsers. For RAW metadata inspection, use a desktop tool built on ExifTool.
