Question 1

What is image dithering?

Accepted Answer

Dithering uses a limited color palette to simulate colors not in that palette by arranging pixels in patterns. It creates the illusion of more colors than are actually available — a technique used in retro graphics, print, and digital art.

Question 2

What dithering algorithms are available?

Accepted Answer

Floyd-Steinberg, False Floyd-Steinberg, Atkinson, Stucki, Jarvis-Judice-Ninke, Burkes, Sierra, Two-Row Sierra, Sierra Lite (all error-diffusion), Ordered Bayer 2×2, Bayer 4×4, Bayer 8×8, and Random noise.

Question 3

Can I dither videos and GIFs?

Accepted Answer

Yes. Upload an MP4, WebM, or animated GIF. The dithering effect is applied live as the video plays. You can export as WebM (60fps) or as an animated GIF that preserves the original frame timing.

Question 4

Is my file uploaded to a server?

Accepted Answer

No. All dithering is processed entirely in your browser using the Canvas API and Web Workers. Your images, GIFs, and videos never leave your device.

Question 5

What does the Scale slider do?

Accepted Answer

Scale sets the pixel grid size before dithering. At scale 1 every source pixel is dithered individually. At scale 4 the image is sampled at ¼ resolution, then upscaled — producing a chunky 8-bit pixel art look.

Question 6

What color presets are available?

Accepted Answer

25+ presets covering retro consoles (Game Boy, Game Boy Pocket, Virtual Boy, NES, Pico-8, C64, Apple II, CGA, EGA, ZX Spectrum), monochrome monitors (Green Mono, Amber Mono), and aesthetic palettes (Risograph, Synthwave, Vaporwave, Sunset, Forest, Ice, Dracula, Nord, Sepia, Neon).

Question 7

What export formats are supported?

Accepted Answer

Images export as PNG or JPG at original resolution. Animated GIFs export with per-frame timing matching the source GIF, with optional 1×–4× upscale. Videos export as WebM (VP9, 60fps, 2× upscaled).
