PNG (Portable Network Graphics) is an image format supporting lossless compression and an Alpha transparency channel. In GIS, PNG is often paired with world files (.pgw) and projection files (.prj) to carry georeferencing — suitable for raster tiles and map graphics that need a transparent background.
Converting JPEG2000 to PNG is one of the most common workflows in GIS. JPEG2000 data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while PNG is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your JPEG2000 files, keeps geometry and attributes intact, and writes clean PNG 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 JPEG2000 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 JPEG2000 files at once and each one produces its own PNG output.
Upload your JPEG2000 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.
Download the PNG file. Each input produces its own output, ready to use in your GIS, web map, or archive.
