DALL·E export cleaner
What a DALL·E export may contain
Files from DALL·E may carry C2PA Content Credentials and OpenAI provenance fields. Exact fields vary by format, product version and download path.
Inspect first when you need to know what is present, then make a separate clean distribution copy for sharing.

Procédure recommandée
From DALL·E export to clean copy
1
Download the original
Export or download the full file directly from DALL·E.
2
Inspect the markers
Use the checker to identify C2PA, XMP, EXIF or PNG text chunks.
3
Create a distribution copy
Clean, download and use that derivative for social uploads.

Guide approfondi
Metadata a DALL·E file may contain
A download from DALL·E may include C2PA Content Credentials and OpenAI provenance fields. The exact structure varies with file format, product version and download path, so inspect the actual export instead of assuming.
The checker reads the file on your device and groups the signals it finds. It does not alter the content or claim to prove that an image was generated by AI.
05
Guide approfondi
Clean DALL·E files without changing pixels
For JPG, PNG and WebP, the cleaner copies the compressed image payload and removes only selected metadata segments or chunks. It does not use canvas, resize the image or introduce another lossy JPEG encode.
HEIC-to-JPG is the explicit exception because format conversion requires decoding and encoding. Keep the untouched DALL·E export whenever provenance or authorship records may matter.
06
Guide approfondi
Prepare a DALL·E export for sharing
Download the full file from DALL·E, inspect its markers, choose the narrowest suitable cleaning scope and verify the clean copy. Then follow the guide for the destination where you plan to publish.
Upload platforms process files differently and may use signals beyond metadata, so removing file fields is not a promise about labels or distribution.

FAQ
Questions fréquentes
What metadata is common in DALL·E files?
C2PA Content Credentials and OpenAI provenance fields.
Can a prompt be stored in the file?
It can, particularly in PNG files from image-generation workflows. The checker reports readable text chunks.
Should I always remove C2PA?
No. Preserve provenance when transparency, authorship or a platform policy requires it.
Is my DALL·E file uploaded to a server?
No. Inspection and cleaning happen locally on your device in the browser.
Does cleaning reduce image quality?
JPG, PNG and WebP metadata is rewritten without re-encoding the pixel payload. HEIC-to-JPG conversion is the exception.
Which formats support pixel-preserving cleaning?
JPG, PNG and WebP use metadata-only processing. HEIC/HEIF is converted to a clean JPG.
Why should I inspect before removing metadata?
Inspection shows which metadata is actually present, helping you choose the right scope and avoid discarding useful records.
Can I process several exports together?
Yes. Process up to 30 files per batch, with a maximum size of 15 MB for each file.
What should I do after cleaning a DALL·E export?
Inspect the download, then select the file with the clean suffix when uploading to the destination platform.
