Compatibility test results

We run AI Label Remover on real image files — from ChatGPT, Adobe, Nikon and Truepic, and files signed with the official C2PA SDK — and check every result with tools that share no code with ours. Download any file below and check it yourself.

Files tested: 15
Formats: JPEG, PNG, WebP, AVIF, HEIC
Passed: All, in both modes
Last run: November 2, 2026

How we test

Each file is cleaned twice by the same code that runs in your browser — once with All metadata and once with AI markers only — and each cleaned copy must pass four independent checks:

The official C2PA SDK (c2pa-python, built on the C2PA Rust library 0.91.3) finds no Content Credentials.
ExifTool 12.76 and Pillow find no GPS location, no AI digital source type and no AI tool names — and, with All metadata, no EXIF, XMP or IPTC at all (only the orientation tag is kept, so photos stay upright).
With AI markers only, the camera details are still there.
Pillow 13.0.0 and pillow-heif decode exactly the same pixels as from the original.

Results from the cleaner at commit 07d4f83. The JSON report next to each file is the same report the tool gives you.

What these tests don’t show

Watermarks. The ChatGPT image’s own Content Credentials record that it was watermarked. That watermark is part of the pixels, so it is still there after cleaning — as with Google’s SynthID.
Platform labels. We test what is in the file, not whether a platform shows a label: platforms also run their own checks and use what you disclose.
Validity. Some C2PA test files carry deliberately broken credentials (an invalid signature, a tampered assertion). Cleaning removes credentials whether or not they are valid.
Every app. This is a small, growing set. More files from real apps are being added.

Found a file that doesn’t clean properly? Email support@ai-label-remover.com — if you can share it, we’ll add it to the tests.
