Converting GRIB to JPEG2000 is one of the most common workflows in GIS. GRIB data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while JPEG2000 is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your GRIB files, keeps geometry and attributes intact, and writes clean JPEG2000 output — entirely in your browser, so your data never leaves your device.
No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.
Yes, completely free with no sign-up and no usage limits.
By default the output keeps the source coordinate system. If your GRIB file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.
Yes — drop several GRIB files at once and each one produces its own JPEG2000 output.
Upload your GRIB file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
