Invert image colors into film negatives instantly inside your web browser. Free, one-click color inversion with no upload and no watermark.

## What is Invert Image Colors?

Invert images for scientific inspections, high-contrast dark mode reading, or creative photographic negative effects. The transformation subtracts each red, green, and blue byte from 255 in real time.

## How to use Invert Image Colors

1. **Add your file or input** — Choose a supported file, drag it onto the upload area, or type/paste the data this tool works with.
2. **Adjust the options** — Pick the output format, quality, size or other settings the tool offers. Defaults work well for most files.
3. **Process and download** — Run the tool and save the result. Processing happens in your browser, so nothing is uploaded to a server.

## Frequently asked questions

### How is color inversion calculated mathematically?

Every pixel channel is inverted using the formula (255 - Value). Pure white (255, 255, 255) becomes pure black (0, 0, 0), and blue becomes yellow.

### Does inverting an image invert the transparent background?

No. The alpha channel remains completely untouched, so transparent PNGs and logos retain their transparent borders.

### Is color inversion useful for reading scanned documents?

Yes! Inverting black text on white paper produces white text on a black background, creating an eye-friendly dark mode for night reading.
