Technical note

ASC to JXR: what carries over and what does not

Every cell in an ASC file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. JXR stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the JXR returns a shade, not an altitude. ASC stores pixels without compression loss and JXR does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

Needed to convert my professional photos to JXR for long-term storage and was pleasantly surprised by reaConverter's handling of this format. The compression maintains exceptional dynamic range while reducing file sizes significantly compared to TIFFs. The batch processing saved me hours of work, and the quality preservation is outstanding - perfect for my HDR photography archive.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

ASC to JXR Conversion

What are ASC files?

The ASC (Esri ASCII Grid) format stores raster geospatial data as plain text. Developed by the Environmental Systems Research Institute (ESRI), it describes a rectangular grid of cells using a short header — number of columns and rows, coordinates of the lower-left corner, cell size and a no-data value — followed by the cell values themselves, written row by row as ordinary numbers. Because the entire grid is human-readable text, ASC is widely used for exchanging elevation models, slope maps and other continuous surfaces between GIS packages that would otherwise share no common binary format.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
