Windows Cursor (CUR) is the mouse cursor format for Windows, supporting static and animated pointers with hotspot definitions.

When Should You Use JXL vs CUR?

JXL vs CUR: Key Differences

• •The core technical difference: JXL relies on lossy compression whereas CUR uses lossless compression.
• •Moving from JXL (lossless) to CUR (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: CUR supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: varies for JXL vs Very small, typically under 50KB for CUR.
• •Use case fit: JXL targets modern web, archival photography, high-quality imaging and CUR targets windows ui cursors, mouse pointer graphics — your choice depends on which workflow stage you are serving.

Advantages of JXL

• ✓The lossy nature of JXL means file sizes stay reasonable while handling Modern web, archival photography, high-quality imaging efficiently.
• ✓From mobile devices to enterprise servers, JXL is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using JXL thanks to its efficient compression.
• ✓JXL is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of CUR

Troubleshooting JXL to CUR Conversion

• !CUR shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted CUR image looks washed out → the source JXL likely uses a wider color space than CUR supports
• !CUR file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted CUR looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
