How it works

PNG Metadata Remover in 4 steps

  1. Drop a PNG onto the tool or click Choose File.

  2. Review the report - text chunk keywords are listed by name.

  3. The cleaned copy is produced automatically and losslessly.

  4. Download it; the original file on disk is untouched.

When to use it

PNGs hide metadata differently than photos: instead of EXIF, they carry text chunks - author tags, source-software stamps, comments, timestamps, and increasingly full AI-generation prompts written in by image generators. This tool reports what's inside your PNG and produces a clean, pixel-identical copy on your device.

  • Strip AI-generation prompts and parameters embedded by image generators.
  • Remove creator and software tags from design exports before delivery.
  • Clean screenshot metadata before attaching to public bug reports.

Format & quality notes

  • PNG metadata lives in tEXt/iTXt/zTXt chunks plus optional EXIF and timestamp chunks - the report names what it finds.
  • Cleaning a PNG is fully lossless: the output pixels are identical to the input.
  • Many AI tools (Stable Diffusion and others) write the entire generation prompt into PNG text chunks - worth checking before you share.
FAQ

Questions about the PNG Metadata Remover.

What metadata do PNGs contain?

Text chunks with keywords like Author, Software, Comment, or parameters; a timestamp chunk; and sometimes a full EXIF block. Screenshots and AI-generated images are the usual carriers.

Can PNGs really contain AI prompts?

Yes - several generators embed the full prompt, seed, and settings as PNG text. If you'd rather not publish your prompt with the image, clean it first.

Is the cleaning lossless for PNG?

Completely - PNG is re-encoded losslessly, so the visible image is bit-identical while the metadata chunks are gone.

Does my file leave my device?

No. Both the inspection and the cleaning run in your browser.
