Grainrad — ASCII art and retro effects for images and video
A free WebGPU-powered browser editor with ASCII, dithering, halftone and other effects for images, GIFs and video.

Ditther is a browser-based editor for expressive image treatments and poster design. Its focus is on distinctive textures: pixels, halftone dots, dithering, character art, distortion and retro effects. It offers a useful starting point for exploring a different visual direction with an existing photograph or graphic. Effects can be combined with colour adjustments, typography, shapes, masks and layers. Duotone helps build a restrained palette, while Looks collect reusable settings. Some of the more advanced controls are tied to paid plans. Shuffle and Remix make experimentation quicker by suggesting new combinations that can be refined manually. This approach suits covers, posters, music graphics and social visuals when one source image needs several different treatments. The service also supports video and animated effects. Image export is available, with paid features extending video and output quality; check the current editor for the precise formats and limits you need. The official FAQ states that media are processed locally in the browser. Core tools are available free, with Pro upgrades for additional capabilities. Public pages describe some free export limits inconsistently, so verify the current plan before relying on a particular resolution or video feature. Use source materials you have rights to, and check the separate terms for any supplied backgrounds.
Free access does not grant rights to third-party images or supplied backgrounds. A blanket commercial-use licence for all such assets was not verified; check the terms for each asset.
