Convert photos to retro 1-bit dithered or halftone art (Floyd–Steinberg, Atkinson, Bayer).
Image Dithering & Halftone converts a photo into a retro 1-bit image using Floyd–Steinberg, Atkinson, Bayer, threshold, or halftone-dot algorithms, with adjustable pixel size and two-color output. It runs fully in your browser and exports a PNG — no upload.
Turn any photo into a retro 1-bit dithered or halftone image, entirely in your browser. Choose from classic algorithms — Floyd–Steinberg and Atkinson error diffusion, ordered Bayer dithering, a hard threshold, or newspaper-style halftone dots — and fine-tune the pixel/dot size, brightness threshold, and contrast. Pick any two colors for a duotone 1-bit look (great for e-ink, zines, stickers, cover art, and that Mac-classic / dithered aesthetic). Nothing is uploaded — the image is processed locally with the Canvas API and can be downloaded as a PNG.
Image Dithering & Halftone lets you instantly convert photos into retro 1-bit dithered or halftone art right in your browser. Because processing happens locally using the Canvas API, your images are never uploaded to a server, guaranteeing full privacy. It offers multiple classic algorithms like Floyd–Steinberg and Atkinson error diffusion without requiring software installation or account creation.
Good to know: Very large image files may experience slower rendering speeds when processed entirely within the browser.
