Mes3D is a free, private 3D model viewer that runs entirely in your browser.
Mes3D is a free online viewer for 3D models. Open a file and it renders instantly in your browser — rotate, zoom and pan it, switch to preset views, measure distances, and read off dimensions, volume, surface area, estimated print weight, watertightness and overhangs. STL, OBJ, PLY, glTF, GLB, 3MF, FBX, DAE, 3DS, AMF files are all detected automatically.
There is no upload step, because there is no server to upload to. Every file is parsed and rendered by your own browser, so confidential models, client work and prototypes never leave your machine. That also means it works offline once the page has loaded.
Every feature is available without signing up, without a subscription and without a paywall. We built Mes3D because checking a mesh before printing shouldn’t require installing desktop software.
The same viewer and analysis tools ship in the Mes3D app for iOS and Android, for when a model arrives on your phone instead of your desktop.
