PurifyAI
GPT Image & DALL-E 3

Strip DALL-E 3 Content Credentials and metadata

Images generated by DALL-E 3 through ChatGPT carry C2PA Content Credentials identifying them as AI-generated. PurifyAI removes that manifest along with EXIF and text metadata, entirely in your browser.

  • Removes C2PA Content Credentials manifests from PNG and JPEG
  • Strips EXIF software tags and XMP provenance packets
  • Lossless — the container is rewritten, pixels are copied through
  • Free to inspect, no account needed to see what is embedded

Try it now — scan a file

No upload

Pick a PNG or JPEG and the DALL-E scanner reads its bytes right here in your browser. Nothing is sent to a server — you can check your network tab. Free downloads: 5 of 5 left today.

How it works

Three steps, no account required to try it.

1

Load your file

Drop an image or video into the browser. It is read into memory locally — there is no upload request, which you can confirm in your network tab.

2

Review what was found

The engine walks the actual byte structure and lists every metadata segment it finds: C2PA manifests, EXIF blocks, XMP packets and text chunks.

3

Export a clean copy

Metadata segments are dropped and the remaining bytes are rewritten. Pixels are untouched, so there is no re-encode and no quality loss.

What this tool handles

🔐

C2PA manifest stripping

JUMBF boxes in PNG (caBX) and C2PA segments in JPEG are both located and removed.

🧾

EXIF and XMP removal

Software attribution, timestamps and XMP provenance packets all go with it.

🎨

Colour-safe

ICC profiles are detected and preserved even though they share a JPEG marker with C2PA data.

📐

Optional logo masking

If your export carries a visible corner mark, the Studio can mask and reconstruct that region too.

📦

Batch mode

Process a full set of ChatGPT image exports in a single queue.

Frequently asked

What are Content Credentials?

Content Credentials is Adobe and the C2PA consortium's name for a signed provenance record embedded in a file. OpenAI attaches one to DALL-E 3 output so downstream tools can identify it as AI-generated. It is stored in a specific metadata segment, which is what this tool removes.

Will this reduce my image quality?

No. Metadata scrubbing rewrites the container around your image data — it drops the metadata segments and copies the pixel data through byte for byte. There is no decode and re-encode step, so the output is pixel-identical to the input. ICC colour profiles are deliberately preserved so colours do not shift.

Do my files get uploaded anywhere?

No. The scrubbing engine is JavaScript running in your own browser tab. There is no upload endpoint and no server-side processing queue, so your media never leaves your device. You can verify this by opening your browser network tab while you scan a file.

Does removing C2PA make an image undetectable as AI?

No, and we would not claim otherwise. Removing the manifest removes one declared signal. Classifier-based detection, pixel-level watermarking and platform-side provenance records are separate mechanisms that this tool does not touch.

Is it legal to remove watermarks and content credentials?

It depends entirely on the media and your intent. Removing marks from work you own or are licensed to edit is normally fine. Stripping provenance data to pass AI-generated media off as authentic in journalism, elections, legal evidence or identity documents is prohibited by our terms and may be unlawful where you are. You are responsible for how you use the output.

Is there a free tier?

Yes. You can scan and inspect files without an account at all. A free account adds a daily cleaning quota, and paid plans raise that quota and unlock batch processing and API access.

Your files never leave your device

Every scrub runs in your browser tab. There is no upload endpoint, no queue, and no copy of your media on our side — by architecture, not policy.
