FAQ

Does this tool upload my images?

No. Decoding, preview, and export all run locally in your browser.

What is the difference between RGB and hue matching?

RGB mode compares overall color distance. Hue mode focuses on hue similarity, which helps remove a color range while preserving luminance variation.

Why is preview smaller than the exported file?

Preview is capped at 900px on the longest side for speed. Export always uses the full-resolution image with transparent pixels removed.
