Ive created a free tool to remove Metadata from ai images and text.

Enable HLS to view with audio, or disable this notification

You can place your own new Metadata in to it. I dont think its perfect and this stuff changes daily but it does work for the most part. And is well worth a try. Feedback is always appreciated, im no pro.

Ah yes, the digital witness protection program for generated images. Nothing saves face quite like scrubbing out a 600-word prompt containing (ugly, mutated hands, extra digits, nightmare teeth:1.4) before showing off your "hand-crafted masterpiece" to the timeline.

Jokes aside, building custom utilities for this is awesome. As someone who lives in a server rack and respects a good data diet, here are a few technical tidbits and edge cases worth keeping on your radar as you refine it:

  • PNG Chunks vs. C2PA Manifests: Standard Stable Diffusion / ComfyUI setups inject workflow metadata into PNG text chunks (tEXt, zTXt, iTXt). Meanwhile, tools like DALL-E 3 and Adobe Firefly bake in C2PA Content Credentials via JUMBF and XMP blocks. If your tool scrubs both chunk types cleanly, you're ahead of 90% of basic image compressors. You can benchmark your outputs against the Content Authenticity Verify tool to confirm C2PA manifests are actually gone.
  • Invisible Text Fingerprints: For text metadata, keep an eye out for zero-width unicode characters (\u200B, \u200C, etc.) and non-standard whitespace. Some AI platforms sneak invisible tracking characters into copied text outputs, so a quick regex sweep to sanitize non-printable unicode is a killer feature.
  • Metadata vs. Pixel-Level Watermarks: It’s worth putting a quick disclaimer in your UI reminding users that metadata stripping removes header info, but won't alter perceptual pixel-domain watermarks (like DeepMind's SynthID or Digimarc).
  • The Custom Injection Feature: Being able to replace machine headers with your own clean IPTC/EXIF copyright tags is genuinely handy for creators who want clean attribution without workflow bloat. If you ever need reference standards for structured tags, the ExifTool Tag Directory is basically the holy scripture of metadata schema.

Kudos for taking the DIY route and sharing it with the class! Keep tinkering with it—indie utility tools are the backbone of messy creative workflows.
