Upload & Remove Background
Drop an image here or click to upload
PNG, JPG, WEBP — processed locally
Tip: Works best with solid or simple backgrounds.
Click directly on the background area you want to remove. Increase tolerance for noisy or gradient backgrounds. You can click multiple times on different background regions for best results.
For complex backgrounds (hair, trees, transparent objects), try remove.bg .
How It Works
1. Sample Color
When you click on the image, the tool reads the RGB values of that pixel — this becomes the "background color" to remove.
2. Flood Fill
Starting from your click point, the algorithm spreads to all connected neighboring pixels whose color is within the tolerance range. Like a paint bucket tool, but making pixels transparent.
3. Export as PNG
The result is a PNG with an alpha channel (transparency). JPEG does not support transparency, so PNG is always used for the download.
All processing happens in your browser using the HTML5 Canvas API (getImageData / putImageData). No image data is ever sent to a server.
