What It Does

Reads every pixel from the uploaded image and compares it to the chosen background color using Euclidean distance in RGB space. Pixels within the tolerance range are either set to fully transparent or replaced with a new color. Pixels just outside the tolerance range receive proportional alpha blending for smoother edges.

Common Use Cases

  • Green screen: Remove chroma key backgrounds from photos or game sprites.
  • Sprite sheets: Convert solid-color sprite backgrounds to transparency.
  • Logo cleanup: Remove white or black backgrounds from logos.
  • Background swap: Replace one background color with another in batch.

How To Use

  • Drop an image or browse for a file.
  • Click directly on the image to sample the background color automatically.
  • Adjust tolerance — higher values remove more similar shades.
  • Choose Transparent to export a PNG with alpha, or Color to swap the background.
  • Click Apply to preview, then Download PNG.
