Remove Background
Detect background from image corners and make it transparent.
Auto-detect and erase flat backgrounds from any sprite.
The Remove Background tool samples the corners of your image, detects the dominant background color, and erases it within a tolerance you control — producing a clean transparent PNG that drops straight into Unity, Godot, RPG Maker, Phaser, or any other 2D engine.
Unlike generic AI background removers, this tool is built for sprites: hard edges stay hard, palette integrity is preserved, and you keep full control via the tolerance slider.
How to use the Remove Background
- 1
Upload your sprite — anything with a roughly uniform background works best.
- 2
Adjust the tolerance slider higher if remnants of the background remain, or lower if real sprite pixels are being erased.
- 3
Click Remove background and download your transparent PNG.
What you can build with it
- Strip white or solid-color backgrounds from generated sprites
- Clean up scanned hand-drawn pixel art
- Prepare item icons for transparent inventory slots
- Normalize sprites from mixed asset packs to a common transparent format
Frequently asked
Does it work on photos?+
It's optimized for flat-background sprite art, not complex photos. For photos with busy backgrounds, an AI segmentation model would be a better fit.
Does the tool upload my image anywhere?+
No — everything runs in your browser. Your sprite never leaves your device.
Why are parts of my sprite being erased?+
Lower the tolerance. If your sprite contains colors close to the background, increase contrast or use a different starting background.
