The .3ds format comes from Autodesk 3D Studio for DOS and is one of the oldest mesh formats still in circulation. Despite hard limits — 16-bit vertex counts, 8.3 material names — enormous archives of legacy models exist in .3ds, so being able to read it still matters.
USDZ packages Pixar’s Universal Scene Description into a single uncompressed ZIP for Apple’s AR Quick Look. An iPhone or iPad can open a USDZ link directly into augmented reality from Safari — no app required — which makes it the format for AR product previews on Apple devices.

Yes — free with no accounts, no watermarks and no file-size limits. Conversion runs on your own machine, so there are no server costs behind it.
No. The converter runs entirely in your browser using WebAssembly. Your .3ds file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where USDZ supports them, and you can optionally merge everything into a single mesh during conversion.
Yes. Every converted model opens in the built-in 3D viewer with an assembly tree, display modes and section views, so you can inspect the result first.
3DS is reduced to geometry, hierarchy and one flat base color per part before export, so format-specific metadata and animation do not carry through. The USDZ result contains the converted geometry and flat colors, but no source textures, rigs or animation tracks.
