What is a .JPF file?
Everything worth knowing about JPEG 2000 Part 2 Extended Image (JPX).
A JPF file is a JPEG 2000 Part 2 (JPX) extended image, a more capable variant of the .jp2 format that uses wavelet compression. Open it with IrfanView (plus its JPEG 2000 plugin) or XnView MP on Windows, or Preview on Mac. No major browser except Safari can display it, so the fastest fix for sharing is converting to JPG or PNG.

Frequently asked questions
Is my .JPF file uploaded to a server?
No. Your .JPF file is decoded with JavaScript and WebAssembly. The decoders are downloaded once from a public CDN.
How do I see the other pages of a TIFF?
Use the arrows above the image, the page thumbnails in the side panel, or the [ and ] keys. Every page can be saved separately as PNG or JPG.
Why do some TIFF tags look like numbers?
Tags are stored as raw values. We translate the common ones (compression, color mode, resolution, orientation) and list the rest exactly as they appear in the file.
Can I view GeoTIFF or GeoJP2 maps?
We show the image and tell you it's georeferenced. To see it on a map with coordinates, open it in our Map Viewer.
Is my 16-bit or HDR image shown accurately?
Images with more than 8 bits per channel are scaled to 8 bits for display and export. The original precision is listed in the structure panel.
