Local browser-based 3D conversion

Convert STL to GLB in your browser

STL is widely used for 3D printing, but it does not store materials or textures. Converting STL to GLB can make a model easier to preview, share or use in a web-based 3D workflow.

Open the converter and upload your STL Read about textures

Best used for

3D print model previews
Simple web-based 3D viewing
Sharing geometry in a more modern 3D format

Important notes

STL does not contain textures, UVs or rich material information.
The exported GLB can contain the geometry, but it will not magically restore textures that were not in the STL file.
Use GLB, GLTF, USDZ or OBJ ZIP when texture preservation is important.

How to use Convert3Dfiles

Open the converter.
Drop your 3D file, or upload a ZIP when the model uses external texture files.
Preview the model for free in the browser.
Choose your export format and convert. One export uses one credit.

For textured OBJ or GLTF workflows, upload the model and all linked assets together in a ZIP file. This gives the converter the best chance to preserve textures and materials.

Are my files uploaded?

No. Convert3Dfiles is designed to run the conversion locally in your browser.

Can textures be preserved?

Texture preservation depends on the input format. GLB, GLTF ZIP, USDZ and OBJ ZIP are usually better choices for textured workflows than STL or PLY.

Does preview cost credits?

Preview is free. Exporting a converted file uses one credit.
