NetCDF Viewer — Open .nc Files Online, Free and Private
A browser-based NetCDF viewer. Drop a .nc file and immediately see its variables, dimensions, attributes, and data — including hyperspectral cubes rendered band by band. Nothing is uploaded.
Open the NetCDF viewer
- Reads NetCDF3 classic and NetCDF4 (HDF5-based) files
- Variable table, global attributes, and metadata inspection
- Band previews with percentile stretching and colormaps
- NASA EMIT-style scenes: 285-band cubes open locally via streaming
Most NetCDF viewers are desktop tools (ncview, Panoply) or upload your data to a server. This one runs entirely in your browser with WebAssembly decoders, which makes it a quick way to inspect a scene, check a variable name before writing code, or look at a cube on a machine without a scientific Python stack.
