Transparent PNG - Quick Cheat Sheet

Pick a color (or click on the image) that you want to remove.
Tolerance controls how different a pixel can be from the target color and still be removed (0 = exact match only; 255 = very broad).
All processing runs locally in your browser via <canvas>. Your image never uploads.
Edges are softened by partial transparency when pixels are close to the tolerance threshold (simple feathering).
Download saves a PNG that preserves transparency (alpha channel).
Formats: Works with PNG/JPG/WebP. SVGs are rasterized first at their intrinsic size.

How it works (brief)

Image is drawn to an off-screen canvas. We scan each pixel and compute Δ = max(|r-R|, |g-G|, |b-B|) (or similar distance).
If Δ ≤ tolerance, alpha is reduced; exact matches become fully transparent.
Close colors get proportionally reduced alpha for a smoother edge instead of hard halos.
