How color inversion works
The browser subtracts each red, green, and blue channel from its maximum value. The alpha channel and original source file remain unchanged.
Practical answers
- Black becomes white and white becomes black.
- Red changes toward cyan, green toward magenta, and blue toward yellow.
- The effect is calculated in the browser after file selection.
- The output downloads as PNG.
- The original file is not overwritten.
- Transparent areas retain their alpha value.
- Large images may use more browser memory.
- Color inversion does not improve every low-contrast image.
- Only browser-readable JPG, PNG, WEBP, and BMP files are offered in the picker.
- Review the preview before downloading.
