PICO-8 Palette Converter
PICO-8 is Lexaloffle's fantasy console (2015): a deliberately limited virtual machine with a 128×128 screen and a fixed 16-colour palette that pixel artists now use well beyond PICO-8 itself. This tool maps your image onto those 16 colours at 128 pixels across, a good starting point for sprites, cartridge labels and mock-ups.

Why use Aback Images for pico-8 palette
Real hardware palettes
Colours from the NES, Game Boy, PICO-8, Commodore 64, IBM CGA and EGA, classic Mac OS and 1 and 2-bit greys, rather than a palette guessed from your image.
Chunky pixels on demand
Set how many pixels across the picture should be, from full resolution down to a few dozen.
Dithering
Optional dithering mixes palette colours to suggest shades a small palette lacks.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
About PICO-8 Palette
Limitations
- Each pixel is mapped to the nearest colour in the palette. Real hardware also limited how many colours could share a tile or a scanline; those rules are not applied, so photos keep more colour variety than the original machine could show.

Frequently asked questions
Can I bring the result into PICO-8?
The colours match PICO-8's default palette. The output keeps your image's size with chunky pixels, so scale it down to 128×128 with Nearest neighbour resampling in Resize Image first, then load it with PICO-8's import command.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
