3D Converter

3D Converter lets you inspect a model and move it into another file format without installing a desktop utility. Its free browser workflow handles common mesh and scene files; the main local model can be up to 100 MB. Large textures and companion files can still exceed the memory available to a browser.

Bring the complete model

An OBJ may need its MTL and texture images, while a glTF may depend on BIN buffers and image files. Select the related files together and retain their names. The local loader rejects missing external resources instead of fetching them automatically. A single GLB or STL is often simpler to carry between applications.

Check what survives

The viewer provides a visual check before conversion. After export, the service reopens the output and compares available geometry and scene properties. Format changes can lose materials, animation, hierarchy or unit information; a successful download is not proof that the next application will interpret the result correctly. Conversion is not mesh repair, so verify scale and printable geometry separately.

Local tools and cloud CAD have different terms

Local conversions and the viewer do not require an account. The current free account also includes five cloud credits per month, with a 50 MB cloud-file limit and 24-hour history. STEP and IGES cloud jobs require an account and upload. Pro increases the cloud allowance and retention. The privacy policy describes website usage and device data collection, and the terms grant broad rights over content submitted to the service. Review those terms before uploading confidential CAD files.
