What is GLORP?

GLORP is an online tool for converting pixel art to SVG. It works locally in your browser, so your images stay on your device and are not sent to a server. It is useful for artists, game asset creators, NFT / collectible makers, poster / print work, and developers.

Monolith Mode

The core GLORP algorithm. It analyzes color adjacency to build complex, multi-anchor SVG paths using greedy meshing optimization. Version 4.0.0 improves vertex merging for even cleaner vector outputs.

Lego Mode

Exact 1:1 pixel-to-rect representation. In v4.0.0, we've implemented a performance detection overlay that warns you before generating heavy SVGs, preventing browser lag on massive grids.

FAQ

Yes — select several files via the file picker or drag multiple images into the page. They will be queued and processed one by one, allowing you to easily batch convert PNG to SVG.
Folder uploads are supported only in the desktop app. On the web we intentionally block folders. Get the desktop version here: Itch.
PNG is recommended (best alpha support). JPG and JPEG are supported too, but alpha/transparency handling is limited on those.
Conversion time depends on image size, mode and device power. Small sprites finish quickly; large images with many colors may take longer. The UI displays progress notifications and falls back to the safe 'Lego mod' if the mesher detects instability.
Yes. We utilize local browser processing through WebAssembly (Pyodide). No image data is sent to any server.
