MeshFormat
What it is
MeshFormat is a free browser converter for moving 3D files among CAD, mesh, web, AR, real-time-engine, and 3D-printing workflows. It reads 20 formats and writes 12 across 229 conversion pairs. Listed readable formats include STL, OBJ, STEP, IGES, glTF, GLB, FBX, PLY, 3MF, 3DS, DAE, AMF, VRML, VTK, 3DM, BREP, OFF, and USDZ. Conversion controls cover scale, up-axis, triangle budget, decimal places, centring on the origin, and merging into one mesh. Additional tools compress models and display wireframes and model statistics. Processing runs in a browser worker with WebAssembly geometry kernels. Models remain in browser memory and are not sent to MeshFormat or third parties; the site says it has no upload endpoint or backend. There are no tracking cookies, advertising pixels, or cross-site identifiers. The free plan needs no account, daily quota, or watermark, with file size limited by device memory.
For and against
For
- Free with no account
- 229 conversion pairs
- Browser-local processing
- Conversion controls included
- No tracking identifiers
Against
- File size depends on device memory
- No proprietary DWG, SKP, or SLDPRT support
- Cannot write binary FBX
- Cannot create parametric CAD solids
The verdict
MeshFormat provides broad, local 3D conversion and basic model tools without accounts or quotas. Its proprietary-format and parametric-CAD limits matter for specialized engineering workflows.
Who it suits
MeshFormat suits people moving models between CAD, mesh, web, AR, real-time, and 3D-printing workflows. It is useful when browser-local processing and format conversion are priorities.
