TIF to ASC Converter
Convert TIF image slices to ASC grids, extract pixel intensity values, set scaling parameters and export plain‑text files for further analysis.
- Windows, macOS, Linux
Open and view TIF files free. Building the mesh needs Voxels to Mesh and Mesh to Points, which requires a paid plan.
How to convert TIF to ASC
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.
Build the surface
Run Voxels to Mesh and set the density threshold of the surface you need.
Turn it into points
Run Mesh to Points. Voxels to Mesh and Mesh to Points require a paid plan.
Export as .asc
Select the point cloud, click Export, choose .asc and save.
What to know about TIF → ASC
- A TIF file holds one image or a stack of slices; a stack of slices can be read as a 3D volume.
- An ASC point file is plain text with the X Y Z coordinates of one point per line.
- The route is Voxels to Mesh, then Mesh to Points, then Export as .asc; both tools require a paid plan.
Online or desktop
Online
In the web app, as in the desktop app, building a mesh from TIF data needs Voxels to Mesh and Mesh to Points, 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 TIF to ASC for free?
Opening and viewing TIF files is free on the Community plan. Building a mesh from them uses Voxels to Mesh and Mesh to Points, which requires a paid plan; exporting the finished mesh as .asc 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 TIF files; a paid plan unlocks Voxels to Mesh and Mesh to Points, 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?
ASC stores only the coordinates of the points as plain text: no units, no mesh and, in its simple form, no colors. Check the scale of the points after conversion, and keep the source file if you need its colors, intensity or other attributes later.
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.
