What we checked ourselves
Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 8 Sept 2026We checked that the link to the project still resolves.
- 14 Aug 2026We read the licence text itself (LICENSE). No unusual restrictions were stated.
- 1 Sept 2026We read the project's own documentation and found no sign that development has stopped.
Where this sits among the 211 tools we list in Image generation
- Works without using a terminal181 of 211
- No API key required196 of 211
- Keeps your data on your own machine33 of 211
- Commercial use confirmed as allowed74 of 211
Only 9 of the 211 meet all of the conditions above.
Counted from our own checks: every tool we list is examined against the same criteria.
What it does
AI images that look like pixel art usually are not: the palette is too large and the grid is misaligned, which makes them unusable as game assets. This tool re-quantises and re-aligns them into genuine pixel art, or converts images into vectors that stay sharp when scaled. There is a browser tool as well as a library. Settings need tuning per image, and it cannot rescue an image whose underlying structure is too far gone.
