Dither Generator
Give any image a retro, low-bit dithered look, right in your browser.
About the dither generator
Dithering simulates extra shades using patterns of a few colours, the way early computers and game consoles rendered images. It creates a distinctive grainy, retro texture. Upload an image, adjust the threshold, and export. Processing happens locally in your browser.
Free, no account, private by default.
What is the threshold control?
It shifts where the pattern turns light areas to dark. Lower keeps more detail bright; higher pushes more of the image into the dithered dark pattern.
Can I use this for pixel art or game assets?
Yes. Dithering pairs well with pixel and lo-fi styles. Send the result to the editor to resize or combine it with other artwork.
Does my image get uploaded?
No. The tool works entirely on your device. Nothing is sent to a server.
