How to Convert WBMP to BMP

Despite the similar name, WBMP and BMP are very different formats — WBMP is a strictly 1-bit-per-pixel format for early mobile displays, while BMP typically supports full 24-bit color in an uncompressed structure that's universally readable by Windows software. Converting WBMP to BMP is useful when legacy mobile graphics need to open in older Windows applications or simple image tools that expect the standard BMP format rather than WBMP's mobile-specific structure.

This doesn't add color back into the image, since the original WBMP data was already limited to pure black and white — it simply changes the container to one with far broader software support.

1. Install Batchify Image Converter and Resizer Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single WBMP.
3. Drag your WBMP file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to WBMP and the "To" format to BMP.
5. Click Convert. BMP files are written to the output folder, fully offline.
