TIFF to OBJ Converter
Convert TIFF image stacks to OBJ 3D models, adjust segmentation thresholds, smooth surfaces and export lightweight meshes for advanced visualization.
- Windows, macOS, Linux
Open and view TIFF files free. Building the mesh needs Voxels to Mesh, which requires a paid plan.
How to convert TIFF to OBJ
Open the TIFF stack
On the CT tab click Open Voxels From TIFF and pick the folder with the slices: MeshInspector reads them as one voxel volume. Opening and viewing it is free.
Build the surface
Run Voxels to Mesh and set the density threshold of the surface you need. Voxels to Mesh requires a paid plan.
Export as .obj
Select the mesh, click Export and choose .obj.
Save
Pick a folder and save the .obj file.
What to know about TIFF → OBJ
- A TIFF file holds one image or a stack of slices; a stack of slices can be read as a 3D volume.
- OBJ is a text format; its materials and textures live in a separate .mtl file and image files.
- The surface is built from the volume with Voxels to Mesh at a density threshold; the tool requires a paid plan.
- OBJ stores no units, like STL.
Online or desktop
Online
In the web app, as in the desktop app, building a mesh from TIFF data needs Voxels to Mesh, which requires a paid plan. Exporting the finished mesh is free.
Desktop
The desktop app runs on Windows, macOS (Apple silicon) and Linux. Use it for large files, many files, and the tools the web app does not have. The free Community plan covers opening and exporting; see Pricing for what the paid plans add.
FAQ
Can I convert TIFF to OBJ for free?
Opening and viewing TIFF files is free on the Community plan. Building a mesh from them uses Voxels to Mesh, which requires a paid plan; exporting the finished mesh as .obj is free. The Pricing page lists what each plan includes, and the desktop app runs on Windows, macOS and Linux.
Do I need an account?
Yes. MeshInspector asks you to sign in, in the web app and in the desktop app. A free account opens and shows TIFF files; a paid plan unlocks Voxels to Mesh, the step that turns them into a mesh. You can see the plans on the Pricing page before you sign up.
Are colors and units kept?
OBJ stores no units, so check the size of the model after conversion. Colors and textures in OBJ live in a separate .mtl file and image files; the exported OBJ carries the mesh geometry, so check the result in your target app if you rely on materials or textures.
Which app should I use for large files?
Use the desktop app. The web app works within your browser's memory, up to about 4 GB, or 16 GB in browsers with 64-bit WebAssembly, while the desktop app uses the memory of your computer. It runs on Windows, macOS (Apple silicon) and Linux.
