DitherLab

A local-first dithering studio with multi-style comparisons, production profiles, batch export, palettes, and portable recipes.

DitherLab is a local-first image studio for turning ordinary pixels into deliberate colour, tone, texture, and detail. EXPLORE DISTINCTIVE TREATMENTS • Choose from 29 dithering, quantization, halftone, stipple, and ASCII algorithms. • Start quickly with 32 curated looks, including PICO-8, Vaporwave, Game Boy, newsprint, film grain, Xerox, and E-ink. • Build custom palettes or import and export palette files. • Tune exposure, contrast, saturation, highlights, shadows, detail, pixel scale, scan path, and perceptual colour matching. COMPARE BEFORE YOU COMMIT • Hold to reveal the original or use the interactive before-and-after comparison. • Inspect pixels with fit, zoom, 1:1, and grid controls. • Explore multiple looks together on the Style Board. • Queue several images and keep per-image recipe overrides. MAKE RISO-INSPIRED ART • Build multi-drum Riso Press treatments with editable inks and tonal ranges. • Adjust screens, paper, registration, texture, and seeded press effects. • Save and reuse deterministic Riso recipes. EXPORT FOR REAL WORKFLOWS • Export PNG, JPEG, WebP, or SVG. • Copy results, create 2× output, target a file size, batch to ZIP, or generate a contact sheet. • Save portable recipes and palette files for repeatable results.
