Frequently Asked Questions
What is STL to GLB conversion?
It changes a 3D model from the STL container or mesh format into a GLB file for another modeling, printing, or preview workflow.
Can I choose another target format?
Yes. Use the Source Format and Target Format dropdowns above. Supported combinations automatically navigate to their dedicated conversion page.
Does this use the same template for every converter?
Yes. All supported 3D file conversion pages share this page template, upload panel, and format selector.
Is this ready for Worker processing?
The page creates a `file_convert` job with source and target parameters. The Worker conversion runner can be connected next.
