Know before you start

Important limitations

  • A simple inversion is not calibrated film-negative conversion and does not correct an orange mask.
  • The resulting color relationships are mathematical rather than an accessibility or brand-color recommendation.
  • JPG output is flattened and re-encoded, so repeated saves can introduce additional compression artifacts.

Common questions

Invert JPG Colors FAQ

Does Invert JPG Colors upload my image?

No. Decoding, canvas processing, previewing, and export happen in the current browser session.

Does the downloaded file replace the original?

No. The tool creates a separate download; the source file on your device is not modified.

Will metadata remain in the result?

Canvas export normally omits camera EXIF and most ancillary metadata. Keep the original if those records matter.
