3D COMPRESSION TOOLS

Make 3D files smaller, without a server.

Compress an STL by storing it as binary and optionally decimating the mesh, or optimise a GLB by welding vertices and removing textures. Everything runs locally; downloading requires an account (5 credits per file).

STL → STLCompress an STL file

Shrink an STL without uploading it: convert ASCII STL to binary and optionally decimate the mesh. See the size before and after.

GLB → GLBCompress a GLB file

Shrink a GLB locally: quantization to 16-bit positions and 8-bit normals, welded vertices, optional decimation and texture removal. Compare the size before and after.
