View an OBJ file in 3D, right in your browser
Drop an OBJ file onto this page and it opens in a 3D view you can orbit, zoom, and inspect. You'll see the model's bounding-box dimensions and its triangle count, so you can check geometry before sending it to a slicer or another tool.
Nothing is uploaded. The file is read and rendered entirely in your browser, so it never leaves your device — which also means it loads as fast as your machine can read it.
How it works
Good to know
FAQ
Why does my model look gray or plain instead of colored?
An OBJ file stores geometry only. Color and surface detail live in a separate .mtl material file plus image textures, which a single .obj doesn't include. When those aren't loaded alongside it, the viewer falls back to a plain neutral shade. The shape is still exactly right — only the appearance is simplified.
What units is the model in, and can I trust the dimensions shown?
OBJ files don't record units — the format just stores numbers. We show the bounding-box size in those raw model units. Whether one unit means a millimeter, centimeter, or inch depends on how the file was exported. The relative proportions are reliable; the absolute scale is only meaningful if you know the export convention.
Can I use this to check if a part will fit before 3D printing?
Yes, for a sanity check. The bounding-box dimensions tell you overall size and the triangle count hints at mesh density. Just confirm your units first (see above), since a model exported in centimeters will look 10x too small if your slicer assumes millimeters. For watertightness and printability, you'll still want your slicer's own checks.
Is there a file size limit?
There's no fixed cap we impose — the limit is your device's memory and your browser. Small and medium OBJ files open instantly. Very large meshes (millions of triangles) may take a moment to parse and can feel heavy to orbit, since all the work happens locally on your machine rather than on a server.
Does my file actually stay private?
Yes. The OBJ is read and rendered by code running in your browser tab. There's no upload, no account, and nothing is written to a server. Close the tab and it's gone from this page entirely. You can confirm this in your browser's network tab — you won't see the file being sent anywhere.
Can I convert the OBJ to another format here?
This page only views OBJ files — it doesn't convert them. If you need to change formats, look for the matching converter page on Cadify, and be aware that geometry-only OBJ conversions won't carry materials or textures that weren't bundled in the first place.
