Format Details
JXL
JPEG XL (JXL) is a next-generation image codec designed as a long-term replacement for JPEG, PNG, and GIF. It offers significantly better compression than JPEG (often 60% smaller at equivalent quality), supports lossless compression, animation, and HDR color. A unique feature of JPEG XL is its ability to losslessly re-encode existing JPEG files, saving storage space without any quality degradation.
imageCUR
CUR is the Windows cursor file format used to store static mouse cursor images for the operating system. It shares the same internal structure as the ICO format and supports multiple sizes and color depths within a single file. CUR files define the appearance of mouse pointers in Windows applications and throughout the OS shell.
imageConverting JXL to CUR: what actually changes
JXL to CUR is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .JXL and .CUR each hold
.JXL is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. .CUR is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the image category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .CUR encodes pixels, dimensions and colour depth — not what the file is about.
When this conversion is the right one
Reach for .CUR when the software, device or platform you are sending to expects it — the content is the same image, only the packaging differs. The reverse direction works the same way, so you can always convert back from .CUR to .JXL using the same tool.
Tips for a clean JXL to CUR conversion
Start from the original file
Convert the .JXL you started with, not an earlier .CUR output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Image/jxl becomes image/x-win-bitmap. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Watch transparency and animation
If the .JXL has a transparent background or animation, confirm .CUR supports it. Where it does not, the background is flattened onto a solid colour and only the first frame survives.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge image files, split or compress the source first.
