About formats

CUR is the cursor image format for Microsoft Windows, structurally nearly identical to the ICO (icon) format but with the addition of a hotspot coordinate that identifies the precise pixel position where mouse clicks register. Introduced with early Windows versions, CUR files use the same container structure as ICO: a directory header listing one or more image entries, each specifying dimensions and color depth, followed by the pixel data for each variant. Like ICO, a single CUR file can contain multiple images at different sizes and color depths, allowing Windows to select the most appropriate cursor image for the current display resolution and color settings. Image data within CUR files can be stored as BMP pixel arrays (for legacy compatibility) or as embedded PNG images (supported since Windows Vista) for alpha-blended cursors with smooth edges. The hotspot coordinate — the distinguishing feature separating CUR from ICO — is stored as an X,Y pair in the directory entry header, typically pointing to the tip of an arrow or the center of a crosshair. One advantage is multi-resolution packaging: a single CUR file provides appropriate cursor imagery across display densities from standard DPI to high-DPI screens. Native Windows integration is another strength — CUR files are loaded directly by the operating system for mouse cursor display without any third-party software. CUR files are used by application developers and theme creators to customize the pointing experience across Windows environments.

XV is an alternate file extension for the VIFF (Visualization Image File Format) developed by Khoral Research as part of the Khoros scientific image processing environment, which originated at the University of New Mexico around 1990. The .xv extension and the .viff extension refer to the same underlying format — a container with a 1024-byte header encoding image dimensions, data type (from single-bit to double-precision float and complex numbers), color space, band count, and optional spatial location metadata, followed by color map data and pixel values. The XV extension became common on systems where Khoros was installed alongside other X Window System tools, and in some research communities .xv was preferred over .viff as a shorter alternative. Khoros itself was a pioneering visual programming system where scientists assembled image processing pipelines by wiring together processing nodes in a graphical canvas — an approach that predated and influenced similar environments in MATLAB, LabVIEW, and commercial remote sensing packages. One advantage of the VIFF/XV format is its ability to store data at scientific precision levels — floating-point and complex number pixel values preserve measurement accuracy that would be lost in photographic formats limited to 8-bit or 16-bit integers, making it valuable for spectral analysis, computational physics output, and satellite imagery. The multi-band architecture provides another strength, allowing a single file to hold dozens of spectral channels from multispectral or hyperspectral sensors without splitting data across multiple files. XV files are supported by ImageMagick and can be converted to modern image formats for visualization or publication.

Frequently Asked Questions

Why convert CUR to XV?

CUR files contain cursor artwork locked in a Windows-specific format — converting to XV lets you reuse that art in designs.

What programs open XV files?

ImageMagick and Khoros/VisiQuest visualization tools open XV format image data

Can I batch convert multiple CUR files to XV?

Upload several CUR files at once. Each one converts to XV independently — download them individually or together when all are done.

Are uploaded CUR files stored permanently?

No. Source files are deleted immediately after processing, and converted outputs are purged from servers within 24 hours automatically.

Will the converted XV keep the original resolution?

Yes — the default conversion preserves the original pixel dimensions

What platforms support the CUR to XV converter?

Any device with a web browser — Windows, macOS, Linux, Chrome OS, iOS, and Android. No app installation is needed.
