How do I convert a BMP file to a CUR cursor file?

Upload your BMP image to our converter, choose the desired cursor size (e.g., 32x32 or 64x64), set the hotspot position if needed, and click Convert. Our tool will generate a CUR file with the proper CUR header and image data, ready for use as a Windows mouse cursor.

Why convert BMP to CUR instead of using BMP directly as a cursor?

CUR is specifically designed for mouse cursors, supporting multiple sizes, custom hotspots, and transparency (alpha channel). BMP files lack these features, and most operating systems require CUR/ICO format for cursor files. Converting also reduces file size compared to raw BMP.

What happens to transparency and color depth when converting BMP to CUR?

During conversion, we preserve the alpha channel if your BMP has one. If the BMP is 24-bit without transparency, we create an alpha mask for fully transparent areas based on specific RGB values (e.g., magenta keying). Color depth is retained up to 32-bit (8 bits per channel) for high-quality cursors. Additional BMP frames (for animated cursors) are also preserved as multiple CUR images.
