Convert 3D models
without uploading them
A free 3D model converter, viewer, compressor and renderer, all running in this tab. Drop a file in and it opens on your own machine: 75 formats, nothing sent anywhere.
Drop a 3D model here
Any of the 75 formats we read, with its textures and sidecar files. It opens in the viewer, where you can look through the scene, inspect the materials and move the parts around.

Converting instead? Pick a pairing and every page says what survives the trip, or compress and render the same file.

Three steps, no install, no sign-in.
- 01
Add your file
Drag the model in, with its textures and sidecars if it has them. Nothing is uploaded: it is read where it already sits.
- 02
Check the preview
The model loads in the viewport before you commit, so a bad axis or a missing texture shows up here rather than downstream.
- 03
Save it
The new file is written in the tab and lands in your downloads folder. No link, no expiry, no account.
Four tools, one promise
None of them has a server behind it.
Between 75 readable and 19 writable formats, with a page for each pairing that says what survives.
Mesh simplification, texture re-encoding and Draco, with a before-and-after report rather than a promise.
Studio lighting, camera presets, transparent backgrounds and turntables, drawn by the GPU you already own.
The scene hierarchy, node and material properties, and a preview of every texture map.

Why nothing is uploaded
Most online 3D object converters copy your model onto a server, convert it there and ask you to trust that it gets deleted. That is not acceptable for work you have not published yet. Here your file is read, parsed, re-encoded and drawn by JavaScript, WebAssembly and WebGL running inside your own browser tab. There is no upload endpoint to trust, because there is no upload.
You can check that in ten seconds: load any page on this site, turn your Wi-Fi off, and use it. It still works. Every one of the 75 formats has also been loaded through the viewer against a real file, with the results published in full, failures included.
