When to strip image metadata
- Publishing AI-generated art — GPT Image 2 and DALL-E embed C2PA provenance signatures and generation prompts inside PNG text chunks. Strip them before uploading to a portfolio site.
- Sharing phone photos without exposing GPS coordinates, device model, or the account that took them.
- Journalism / legal workflows where even container-level metadata can identify a source.

Why strip metadata here
- Canvas re-encode naturally drops EXIF, XMP, IPTC, ICC, and PNG text chunks in one pass — nothing to configure.
- Shows what metadata it found before cleaning (EXIF / XMP / C2PA / prompt text) so you know what you're removing.
- Fully offline — the whole point of cleaning metadata is privacy, so we don't ship the file to a server to do it.
Questions Fréquentes
Why does a GPT Image 2 / DALL-E / Midjourney PNG have metadata to strip?
AI image generators often embed "C2PA" provenance signatures, generation prompt text, or creation timestamps inside PNG text chunks. The image also typically carries the original software fingerprint (e.g. "ChatGPT 2026-04"). Stripping these removes the auditable trail before publishing.
What exactly gets removed?
EXIF (camera / GPS / timestamps), XMP (Adobe / editor metadata), IPTC (caption / keywords), ICC (color profile), PNG text chunks (tEXt / iTXt / zTXt where most AI prompts live), and any other container-level metadata. Only the pixel data is preserved.
Is the output pixel-identical?
Very close but not bit-identical — the tool re-encodes through the Canvas API at quality 0.95 so it can cleanly drop all metadata. Photo-style images look indistinguishable from the original; screenshots with sharp text may show very slight JPEG-style ringing at 95%. For zero quality loss, use a desktop tool that operates on the raw JPEG / PNG bytes (e.g. ExifTool).
Can I use this for privacy / whistleblowing?
For most social-media-grade anonymization, yes. For high-stakes publishing (journalism sources, court evidence), also replace the filename, trim the first and last seconds of any nearby video clips, and re-compress with a different tool chain as belt-and-braces.
Does my image upload anywhere?
No. Everything runs locally in your browser. Open DevTools → Network tab while cleaning — you'll see zero requests leave your machine.
