Chroma Key Remover

Pick a flat green screen, blue screen or solid background color with an eyedropper and make it transparent, using real YCbCr chroma-distance keying.

• Eyedropper: click anywhere on the uploaded photo to sample the exact background color to remove, with a live color swatch.
• Tolerance slider controls a smoothstep alpha ramp between an inner (fully transparent) and outer (fully opaque) threshold, giving soft, non-jagged edges instead of a hard cutout.
• Optional spill suppression, plus a before/after comparison on a checkerboard-transparency background and a PNG download with real alpha.

⭐

• Four CVD types: protanopia, deuteranopia and tritanopia (dichromacy matrices) plus achromatopsia (full color blindness).
• Correct sRGB-to-linear-RGB conversion before the matrix transform, and back again, to avoid the color errors a naive gamma shortcut produces.

• Diff image highlights every flagged pixel in magenta over a dimmed grayscale copy of the first image, plus an exact "X% of pixels differ" stat.
• Clear error if the two images have different dimensions, instead of silently cropping or stretching one of them.

⭐

Image Dithering

Apply real Floyd-Steinberg, Atkinson or Bayer ordered dithering to any photo and reduce it to a 1-bit, 4-shade or reduced-RGB palette — a genuine retro/halftone look, processed locally in your browser.

• Floyd-Steinberg error diffusion with the textbook 7/16, 3/16, 5/16, 1/16 neighbor weights.
• Atkinson dithering (Apple's classic algorithm) distributing only 6/8 of the error for a lighter, higher-contrast look.
• Bayer ordered dithering with a fixed 4x4 threshold matrix, producing the characteristic crosshatch pattern instead of diffusion noise.

⭐

• Adjustable output width from 40 to 200 characters, with row sampling automatically compensating for monospace character aspect ratio so the art isn't stretched.
• Two character ramps — a short 10-character ramp for bold, high-contrast art and a long 70-character ramp for smooth gradients — both real dark-to-light density scales.
• Colored mode renders each character in the cell's real average RGB color as an HTML span, viewable in a scrollable monospace preview and downloadable as a standalone HTML page.
