You can change your CUR images to common formats like PNG, WEBP, JPEG, SVG, PNG32, PNM and PSD. This tool works for both professionals and casual users. Convert your images to the format you want in seconds.
The CUR format is the standard file format for static mouse cursors in the Microsoft Windows operating system. It is structurally almost identical to the ICO (Icon) format, with one key difference: the header contains a defined 'hotspot'. The hotspot specifies the exact pixel coordinate (x, y) that registers the click, such as the tip of an arrow pointer.
A CUR file starts with a header similar to an ICO file, but the 'image type' field is set to 2 (Cursor) instead of 1 (Icon). For each image in the file (it can contain multiple sizes/depths), the directory entry stores the hotspot X and Y coordinates instead of the color planes/bpp fields found in ICOs. The image data itself is typically a BMP with a 1-bit AND mask for transparency, or a PNG in modern versions.
Introduced with Windows 1.0, the format has evolved alongside Windows. Originally supporting only monochrome, it grew to support 16 colors, 256 colors, and finally 32-bit alpha-blended cursors in Windows XP.
