A portable web or AR asset
One binary file can keep geometry, materials and textures together.
Private browser conversion routes
Free Online 3D File Converter
Start with the format you already have. Every listed route opens a real local converter with a 3D preview and downloadable output — no account and no upload queue.
Showing all 15 supported routes.

Supported 3D conversion matrix
A linked arrow opens a tested browser route. A dash means this local exporter is not offered.
Choose the output for the job
A web workflow with editable assets
JSON-based scenes are easy to inspect and pair with external resources.
Broad modeling software support
Simple mesh interchange works across Blender, Maya, ZBrush and many older tools.
3D printing and slicing
The format carries triangle geometry without materials or scene data.
Scans, research meshes or point clouds
PLY can store per-vertex color and vertex-only point-cloud data.
Modern additive manufacturing input
A zipped package can describe richer print data than STL.
SCAN → EDIT
Photogrammetry cleanup
Convert PLY scan geometry to OBJ before retopology, sculpting or repair.
PRINT → SHARE
3D-print handoff
Move STL, OBJ, PLY or 3MF geometry into the format expected by a slicer or collaborator.
DCC → WEB
Web-ready delivery
Package geometry for browser experiences with GLB or glTF output routes.
Private local conversion
Live converters load the source into a local 3D scene and create the download in the same browser tab. STEP uses a local OpenCascade Worker; mesh formats use Three.js loaders. The model is not sent to a conversion API, account or cloud queue.
Real conversion limits
Conversion cannot invent data the source does not contain. STL has no materials; external textures can be missing; DAE to OBJ does not bundle MTL, texture or animation assets; STEP must be tessellated and loses editable CAD history; damaged and extremely dense files may fail in browser memory.
Inspect before you convert
Open the source format first to confirm that the geometry parses, framing looks right and the reported counts are sensible. Every viewer below runs locally and links back to the matching conversion routes.
Frequently asked questions
Are these 3D file converters free?
Yes. Every supported conversion route on this page is free, requires no account and runs locally in a modern browser.
Are my 3D files uploaded to a server?
No. Supported files are parsed, previewed and exported on your device. The converter does not upload the model to TripoSR.ai.
Which 3D formats can I convert?
Current source formats include STL, OBJ, PLY, GLB, glTF, 3MF, DAE and STEP. Available output routes include OBJ, STL, GLB and glTF; the matrix on this page shows every live combination.
Will materials and textures survive conversion?
It depends on both formats and the browser exporter. Geometry is the most portable data. STL drops color and materials, while GLB and glTF can carry richer material data. DAE to OBJ exports geometry but does not generate a companion MTL or texture package.
Why is there no STEP or FBX output?
This collection only links conversions that can produce a real standards-compatible file locally with the current browser engine. STEP and FBX writing are not offered because they require a different export stack.
What should I do with a very large or damaged model?
Repair or simplify it in a desktop 3D application first. Browser memory, malformed geometry and missing external resources can prevent a local conversion even when the format itself is supported.
