What output format does this tool produce?

Always PNG — it is the only common format that supports full alpha transparency. JPEG does not support transparency.

My subject has the same color as the background — what should I do?

Lower the tolerance so the tool selects only pixels very close to the exact sampled color. You can also re-sample different parts of the background and remove them in separate passes.

Can I undo a removal and start over?

Yes — click Reset to restore the original image and start again with a fresh sample.

Is AI background removal used?

No. This tool uses a classic color-based flood-fill approach that runs entirely in your browser with no server round-trip. It works best on images with a solid or near-solid background.

Is my image uploaded to a server?

No. All processing is done entirely in your browser using the HTML5 Canvas API. Your image is never uploaded to any server.

How color-based removal works

The tool uses a flood-fill algorithm starting from the color you click. Pixels whose color is within the tolerance distance of the sampled color are made transparent. Increase tolerance to remove more background, decrease it to protect similar-colored foreground areas.

Edge softness

The feather slider applies a small gradient at the boundary between transparent and opaque pixels, producing smoother edges that blend naturally on any background. Increase it for subjects with soft edges like hair or fur.

Frequently Asked Questions

What output format does this tool produce?: Always PNG — it is the only common format that supports full alpha (transparency). JPEG and WebP with lossy compression do not support transparency.
My subject has the same color as the background — what should I do?: Lower the tolerance so the tool selects only pixels very close to the exact sampled color. You can also click multiple times to re-sample different parts of the background and remove them in separate passes.
Can I undo a removal and start over?: Yes — click Reset to restore the original image and start again.
Is AI background removal used?: No. This tool uses a classic color-based flood-fill approach that runs entirely in your browser with no server round-trip. It works best on images with a solid or near-solid background.
