Images you download from DALL-E are not clean. Depending on whether you saved from ChatGPT, the OpenAI API, or Bing Image Creator, the PNG carries embedded metadata — creation software tags, timestamps, and increasingly C2PA Content Credentials provenance asserting the image was AI-generated by OpenAI.

That matters in three common situations: posting "your art" on Instagram or ArtStation where AI tags trigger backlash or shadow-bans, delivering work to clients who paid for exclusive assets, and submitting to stock sites or contests that reject or flag AI-generated content.

  • What is inside: PNG tEXt/iTXt software fields, creation timestamps, and on newer exports a C2PA manifest (JUMBF jumb/jumbd boxes or APP11 segments after conversion).
  • Why OpenAI adds it: the Content Authenticity Initiative push — provenance so platforms can label AI content. Good for transparency, bad when you need a neutral file.
  • What platforms see: TikTok, Instagram and YouTube already scan uploads for C2PA/AI signals and may auto-label your post "AI-generated" even if you heavily edited it.
  • What clients see: anyone running ExifTool or an online checker can see the OpenAI software tag and creation date.
DALL-E + C2PA double-strip

DALL-E files are a two-layer problem: classic PNG text chunks plus cryptographic C2PA manifests that most EXIF removers miss. Vantawebs removes both in one pass — text chunks and JUMBF provenance. Background reading: how C2PA removal works and does TikTok scan AI metadata?

How to check your file: drop it in the cleaner below. The instant preview flags software tags and any detected C2PA manifest before you clean, so you know exactly what a client or platform would see.

Cleaning workflow: download the highest-resolution PNG from OpenAI first (cleaning before upscaling avoids re-adding metadata), strip with Vantawebs, then do your Photoshop/Lightroom edits on the clean copy. Edits in Photoshop can re-add XMPToolkit history — strip once more before delivery.

Clean it now: drop your DALL-E images below for a free, client-side strip. Nothing uploads — everything runs in your browser.

Client-delivery checklist: confirm the brief allows AI-assisted work, strip the export with the tool below, rename the file from the default generated-image pattern to your studio naming scheme, and re-check the cleaned copy before sending. Agencies routinely run incoming assets through provenance scanners — a clean file with a documented AI-use disclosure keeps you compliant without triggering automated flags.
