GLORP converts raster pixel art into optimized SVG vector files, with a desktop app and a web version listed on its project page.
About GLORP
GLORP is a utility that converts raster pixel art into SVG vector files. It is offered as a downloadable Windows application written in Python and PySide6, with a web version linked from the project page. Images can be processed in Monolith mode, which applies greedy meshing to produce optimized paths; Lego mode, which emits one 1×1 rectangle per pixel; or WebP mode, which produces a lossless raster file. Users drag and drop images or folders, preview files by hovering over their names, and conversion is multi-threaded.
It is intended for genuine pixel art supplied at its original resolution, ideally PNG with hard edges and transparency where needed. Upscaled images, JPEG compression, blur and gradients are read as real color data and produce incorrect or broken output. Lego mode can create thousands of objects in a single file. The project page states no pricing information.
Key features
- Greedy meshing in Monolith mode produces optimized SVG paths
- Lego mode outputs one 1×1 rectangle per pixel
- Lossless WebP export mode for raster output
- Batch folder import with drag-and-drop and hover previews
- Multi-threaded conversion
- Windows desktop app in Python/PySide6, plus a linked web version
Best for: Pixel artists, indie developers and UI designers who need original-resolution pixel art converted into clean SVG or lossless WebP files.
Good for
- Three output modes cover optimized vector paths, per-pixel rectangles and lossless raster.
- The converter follows the pixel grid exactly instead of guessing or smoothing values.
- Batch folder import and multi-threaded conversion suit multi-file workflows.
Watch out for
- Only works correctly with real pixel art at its original resolution.
- Upscaled, JPEG-compressed, blurred or gradient images yield broken or shaded SVG output.
- Lego mode can generate thousands of objects, which the project page flags as a technical warning.

GLORP FAQ
What input files does GLORP require?
Original-resolution pixel art, such as 16×16 or 32×32, in PNG format with transparency if needed and hard edges only. The project page states that upscaled images, JPEG files, blur and gradients are not supported and will break the result.
Which conversion modes are available?
Monolith, which uses greedy meshing for optimized paths and is recommended; Lego, which creates one 1×1 rectangle per pixel; and WebP, which produces a lossless raster file.
What can be done if the source image was enlarged or compressed?
The developer suggests using a clean source close to the original size, or downscaling first with nearest-neighbor scaling and cleaning up colors in an image editor before converting.
