How it works

Perceptual matching

Each non-transparent pixel is mapped to the closest target color using OKLCH ΔE distance rather than simple RGB.

Exact alpha preservation

Transparent and semi-transparent pixels maintain their exact alpha channel values.

Pixel art safe

No resampling or bilinear blur is introduced — pixel boundaries remain razor sharp.

Local performance

Processes directly on HTML5 Canvas without network uploads.
