Frequently Asked Questions

Common questions about STEP to GLB conversion

How does in-browser STEP to GLB conversion protect my privacy?

Unlike legacy file converters that upload your confidential files to cloud servers, OpenFileConverter runs 100% locally on your computer or phone using Rust WebAssembly. Your original STEP files never leave your device memory, guaranteeing zero retention.

What is the main difference between STEP and GLB?

STEP (Standard for the Exchange of Product Model Data) provides mechanical cad interoperability, solidworks, autodesk inventor, cnc toolpaths, while GLB (GL Transmission Format Binary) is optimized for webgl, three.js, babylon.js, ar/vr experiences, and real-time 3d web asset rendering. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting STEP to GLB degrade visual quality?

No. OpenFileConverter uses high-fidelity chroma subsampling with configurable quality levels (default 92%), ensuring virtually indistinguishable image fidelity with sharp edges and rich colors.

Can I convert multiple files in batch?

Yes. You can drag and drop up to 100 files simultaneously. Because processing executes in parallel on your local CPU threads, batch jobs finish in seconds without queue wait times.
