How do I convert a WBMP file to an ICO icon?

Upload your WBMP image, choose a target icon size (e.g., 32x32 or the complete set), enable transparency if desired, then click Convert. The tool decodes the 1-bit monochrome bitmap, resamples it to the selected dimensions, and packages the result as an ICO file that Windows can use natively.

Why should I convert WBMP to ICO instead of keeping the original file?

WBMP is a legacy monochrome format optimized for early WAP browsers and is not supported by modern operating systems or web browsers. ICO, on the other hand, is the standard container for Windows icons and website favicons, supporting multiple resolutions and alpha transparency. Converting ensures your images render sharply in app icons, start menu shortcuts, and browser tabs without distorting dimensions.

What happens to the monochrome data and transparency when converting WBMP to ICO?

WBMP stores only 1-bit black-or-white pixel data, so there are no color profiles, layers, or embedded metadata to preserve. When converting, the pixel values are mapped directly into an ICO entry at the source resolution. For other resolutions (like 16x16 or 48x48), the original bitmap is resampled, which can alter anti-aliasing but not the fundamental monochrome look. Transparency is not part of the WBMP format; our conversion can synthesize an ICO AND mask that makes the background transparent, while the foreground pixels remain black or white. If you disable transparency, the background is filled with the original WBMP's default (usually white).
