PNG Background Remover
Remove solid or near-solid color backgrounds from PNG images — entirely in your browser. Click on the background color in the image to sample it, adjust the tolerance, and download a PNG with a transparent background. Your image never leaves your device.

How It Works
This tool uses two techniques to remove backgrounds:
Flood Fill
Starting from the pixel you clicked, the flood fill algorithm spreads outward to neighboring pixels that are within the color tolerance range. When a pixel's color is close enough to the sampled color, it is made transparent. The algorithm stops at edges where the color changes significantly — preserving the foreground subject.
Flood fill works best for images with a uniform background (white studio shots, flat-color backgrounds, screenshots). It will not remove a non-connected background region on the other side of the subject.
Global Color Match
Checks every pixel in the image and makes it transparent if its color falls within tolerance of the sampled color, regardless of position. Useful for backgrounds that appear on multiple sides of the subject and aren't connected, or for removing a specific solid color from a complex layout.
Tips for Best Results
- Start with low tolerance (15–30) and increase it if fringing or background remnants remain.
- Click in the middle of the background, not near the subject edge, to get the most representative color sample.
- Clean, flat-color backgrounds (white product photos, studio portraits) give the best results. Complex or gradient backgrounds may require a dedicated editor like GIMP or an AI-powered tool.
- Anti-aliased edges — soft edges around curved subjects may leave a thin fringe. Slightly increasing tolerance can help but risks eating into the subject.
- The output PNG preserves alpha transparency so it can be placed on any background color in a design tool.

After removing the background, you may want to resize the PNG or view its metadata. To convert the transparent PNG for web use, try the PNG to WebP converter.
