Image settings client-side

The image never leaves your computer.

2. Pick target color r:– g:– b:–

or click the Original image

3. Tolerance (15)

Higher = remove a wider "nearby" color range (good for gradients / anti-aliased edges).

4. Make that color transparent

Load an image, choose a color, then click "Process Image".

Options

Edge soften (alpha falloff)

Pixels close to the target color will fade instead of instantly disappearing. 0 = hard cutout.
