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.

WBMP (Wireless Bitmap) is a monochrome (1-bit, black and white) image format defined as part of the Wireless Application Protocol (WAP) specification, developed by the WAP Forum (later consolidated into the Open Mobile Alliance) around 1998. The format was designed for the extremely constrained mobile devices of the late 1990s and early 2000s — phones with small monochrome screens, minimal processing power, and narrow bandwidth GSM data connections. WBMP uses the simplest possible encoding: a type identifier byte (always 0 for the only defined type), width and height encoded as multi-byte integers using a variable-length scheme, and the raw pixel data where each bit represents one pixel (0 for white, 1 for black) packed eight per byte. There is no compression, no metadata, and no color — the format is purely a minimal container for delivering small monochrome graphics to WAP-era mobile browsers. One advantage was extreme efficiency on constrained devices — WBMP images could be decoded with virtually zero CPU overhead and minimal memory, critical on early mobile hardware running at single-digit megahertz clock speeds. The tiny file sizes are another strength: a typical WBMP icon occupied just a few hundred bytes, practical for transfer over 9.6 kbps GSM data channels. While the WAP ecosystem has been entirely superseded by modern mobile web browsers capable of rendering full-color JPEG, PNG, and WebP images, WBMP files remain encountered in archived mobile content from that transitional era.

Frequently Asked Questions

Why convert CUR to WBMP?

Archiving or cataloging cursor collections is easier in WBMP, which any gallery or thumbnail viewer can display.

What programs open WBMP files?

Mobile browsers, GIMP, IrfanView, and XnView open WBMP files used in WAP/mobile contexts

Can I batch convert multiple CUR files to WBMP?

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

Will the converted WBMP keep the original resolution?

Yes — the default conversion preserves the original pixel dimensions

How fast is CUR to WBMP conversion?

Most conversions complete within seconds. Larger or more complex files may take slightly longer, but processing happens on fast cloud servers.

Are colors preserved in the CUR to WBMP conversion?

Color information transfers accurately to WBMP. The converter maintains the original color profile as closely as the target format allows.
