Photomosh is a free, fun glitch playground in the browser. Bitgrain adds print effects like dither, halftone and riso, plus a studio to turn the result into a cover or a poster.
Photomosh is great for throwing effects at an image and seeing what happens, and lots of people start there. They usually look for something else when they want finer control over a single look, print style textures rather than pure glitch, or a way to put type on the result without opening another app.
| Capability | Bitgrain | Photomosh |
|---|---|---|
| Where it runs | In the browser, processed on your device | In the browser |
| Main focus | Print effects, layout and video | Glitch and screen style effects |
| Glitch looks | Glitch, RGB split, scanlines, CRT curve, pixelate | A large, playful set of glitch effects |
| Dither, halftone and riso | Built in, with every classic dither algorithm | Not its main focus |
| Layout for covers and posters | Built in studio with templates | Export to another app |
| Video | Timeline editor with effects on clips | Works with video and webcam input |
If you want to stack random glitch effects quickly and see what sticks, Photomosh is quick and fun for that, and it has more pure glitch looks than Bitgrain. Use Bitgrain when the image needs to look printed, when you want precise control over one look, or when the result is going on a cover or a poster.
You can use every effect on the free tier. Free exports carry a small watermark and stop at 1080 pixels, and Pro exports clean at full resolution.
Not true datamoshing, which breaks the frames of a video file. Bitgrain has glitch, RGB split, scanlines and pixel effects that cover a lot of the same ground on stills and clips.
No. Every effect in Bitgrain runs in your browser on your own device.
