Game Boy photo filter,
four greens and big pixels.

Redraw a photo with the original Game Boy's four shades of green, or with the colours of other classic machines. Dithering mixes dots to fake the shades in between, just like the real thing.

How it works

  1. 1

    Open Fun looks

    Pick the Retro tab.

  2. 2

    Drop a photo

    Any photo your browser can open.

  3. 3

    Pick a palette

    Game Boy, Game Boy Pocket, NES, C64, PICO-8, CGA or 1-bit, then download a PNG.

Make it look right

  • Bigger pixel sizes look more like a real handheld screen.
  • Floyd–Steinberg dithering is smooth; Atkinson looks like an old Mac; ordered gives a neat crosshatch.
  • Photos with strong light and dark areas work best.

Questions

Is it free?

Yes. It runs in your browser, so your pictures are never uploaded.

Can I use other colours?

The Duotone tab maps a photo to any two colours you like.

More tricks

Duotone photos, in two colours you choose.

Make a two-colour duotone from any photo, like a gig poster or album cover. Pick presets or your own shadow and highlight colours. Free, in your browser.

Glitch effect, broken on purpose.

Give any photo a glitch look: split the colours, shift slices sideways, add pixel sorting and scanlines. Free, in your browser, and shuffle for a new glitch each time.

QR codes with your picture, checked before you download.

Make a QR code with your logo or photo built in. High error correction keeps it readable, and every code is test-scanned in your browser before you download.
