Flux Image Checker — Detect Black Forest Labs AI Images

使用方法

Drop the image
Drag a PNG, JPEG, or WebP file into the drop zone. Processing runs entirely in your browser.
Read the detection report
The inspector checks for C2PA Content Credentials and EXIF metadata that Black Forest Labs Flux embeds in its generated images.
Understand the verdict
A positive match means the image carries Flux-specific fingerprints and was likely generated by Black Forest Labs Flux.

常见问题

How can I tell if an image is from Black Forest Labs Flux?

Drop the image into the AI Image Inspector on this page. It checks for C2PA Content Credentials and EXIF tags associated with Black Forest Labs Flux.

Does Flux add a watermark to images?

Yes. Flux-generated images carry C2PA Content Credentials — a cryptographically-signed provenance manifest embedded in the file metadata.

What if the image metadata has been stripped?

If the C2PA manifest and EXIF tags have been removed, the inspector will report no AI traces. Screenshots and re-encoded files typically lose these fingerprints.

限制说明

Structural detection, not pixel-levelThe inspector reads C2PA manifests and EXIF tags. It does not run a neural classifier on the pixels. A Flux image that has been re-encoded with all metadata stripped will be reported as 'No AI generation traces found.'
Screenshots defeat detectionTaking a screenshot of a Flux image strips the C2PA manifest and metadata block during re-encoding. The screenshot will read as 'No AI generation traces found.'
PNG, JPEG, and WebP onlyThe C2PA chunk reader works on PNG iTXt/zTXt, JPEG APP11 JUMBF, and WebP 'EXIF' chunks. AVIF, HEIC, and TIFF are not decoded.

平台说明

macOS: Preview.app and Quick Look do not surface C2PA Content Credentials. The inspector is the right tool for diagnosing Flux provenance from any source.
Windows: Windows Photos and File Explorer show EXIF but not C2PA. For full provenance, drop the file into the inspector.
Linux: `exiftool -api RequestAll=3 image.png` shows C2PA claim chains and XMP. The inspector is the right pick when you want a single report covering every Flux fingerprint.
Web: Runs entirely client-side. The image is read as a Uint8Array; all detectors run as pure JavaScript. No upload, no server roundtrip, no telemetry.
