Invert Image Colors
Turn a picture into a color negative by reversing its red, green and blue values. Keep the same image dimensions and preserve alpha transparency.
- Invert all three RGB channels
- Swap light and dark pixel values
- Preserve the alpha channel
Reverse the channel values
Each color channel becomes 255 minus its original value. Black becomes white, white becomes black and other colors become their RGB complements.
Inspect diagrams and line art
Inversion can switch a light-background drawing into a dark-background version. Check colored annotations because they change along with the background.
Keep transparency independent
Only RGB values are inverted. Transparent and partly transparent pixels retain their alpha values in the output.
Distinguish an effect from film recovery
A simple RGB inversion is not a calibrated film-negative conversion. Film color casts and capture profiles need a dedicated photographic workflow.

The RGB operation is reversible, though intervening lossy re-encoding can change pixel values.
This page inverts red, green and blue together.
Each RGB channel is subtracted from 255. Black becomes white, white becomes black and pure red becomes cyan. Transparent pixels keep their alpha values. This creates a digital negative effect, not a calibrated film-negative scanning workflow.
