Is the converter free?

Quick local preview and supported browser exports do not require an account or credits. Private processing starts through a separate signed-in workflow.

Which files can I open?

Open GLB, glTF, OBJ, FBX, STL, PLY, USDZ, and 3MF files up to 50 MB. The export panel reads the source and shows its available targets.

Does AI3DGenerator upload my model?

Choosing, previewing, and using a quick local export keeps the source in your browser. Server processing starts after you choose that mode and confirm the privacy notice.

Are materials and animation always preserved?

No. Format capabilities differ, and a target may not retain the same textures, animation, skinning, or material data. The export panel inspects the loaded model and shows availability and likely fidelity loss before download.

Convert files for web, game engines, AR, and 3D printing.

GLB / glTF

Use GLB or glTF for web viewers, product configurators, portable PBR scenes, and real-time 3D assets.

OBJ / FBX / PLY

Use OBJ, FBX, or PLY for geometry exchange, DCC handoff, game-engine import, or scan-data inspection.

STL / 3MF

Use STL or 3MF for slicers, print planning, prototype checks, and manufacturing preparation.

USDZ

Use USDZ for Apple AR Quick Look, mobile previews, and ecommerce product experiences.

How it works

How to use the free 3D model converter

Start with a browser-local conversion path. Inspect the source, choose an export, and read the fidelity notes before downloading.

01
Open a supported 3D source
Drag and drop or select a GLB, glTF, OBJ, FBX, STL, PLY, USDZ, or 3MF file up to the local size limit.
02
Inspect the model before conversion
Rotate, zoom, change lighting or material, inspect wireframe, and correct orientation so the export decision is based on the loaded model rather than a filename.
03
Choose an export the source can support
Inspect format availability and fidelity notes, then download locally or choose the private processing path.

Private by default

Keep the source model local until you deliberately choose server processing.

Preview, lighting, material inspection, orientation fixes, and supported quick local exports run in the browser without an automatic source upload.

Private conversion and geometry tools start after you choose the server mode, confirm consent, and pass account checks.

Format notes flag texture, animation, skinning, or material changes before export.
