Lumethic
Content Credentials Inspector
Drop in a photo and instantly see its C2PA Content Credentials: who signed it, which software touched it, whether AI was involved – and whether the credentials are still intact.
Drag & drop a photo here, or click to select
JPEG, PNG, WebP, AVIF, HEIC, TIFF, SVG, DNG and ARW are supported

How the inspector works
Drop a photo
Pick any image file from your device. Nothing is uploaded – the analysis runs locally in your browser using the official C2PA library.
We read the manifest
The inspector decodes the embedded C2PA manifest, checks the cryptographic signature and validates that the image still matches what was signed.

Your camera can't write Content Credentials?
Most cameras can't. Lumethic verifies your RAW originals and gives any photo a tamper-proof, shareable authenticity report – no special hardware required.
What are Content Credentials?
Content Credentials are cryptographically signed metadata based on the open C2PA standard (Coalition for Content Provenance and Authenticity), backed by Adobe, the BBC, Google, Microsoft, Sony and many others. They record who created an image, with which hardware or software, and what edits were applied – and they make any later tampering detectable.
This free checker reads and validates those credentials in any photo, the same data that tools like Adobe's Verify site display. Learn more in our C2PA guide.
Private by design: nothing is uploaded
The inspector runs the official C2PA WebAssembly toolkit directly in your browser. Your photo never leaves your device, is never sent to our servers and is never stored anywhere. You can even use the tool offline once the page has loaded.
Why does my photo have no Content Credentials?
Don't be surprised if your photo comes back empty: the vast majority of images have no C2PA data. Credentials are only written by a handful of recent cameras and by software that explicitly supports the standard – and platforms like Instagram, WhatsApp or Facebook usually strip them during re-compression.

Frequently asked questions
This tool validates C2PA manifests with the official Content Authenticity Initiative library. A valid signature confirms the data was not altered after signing; it does not by itself prove how a photo was originally captured.
