How to Convert HEIC to WBMP

WBMP (Wireless Bitmap) is a strictly 1-bit-per-pixel format with no grayscale or color support at all, designed in the era of early WAP mobile phones with extremely limited graphics capabilities. Converting a rich, color-detailed iPhone photo from HEIC to WBMP results in an enormous loss of visual information, reducing the image to pure black-and-white pixels, often using dithering to approximate the original tones through patterns of black and white dots.

This conversion is rarely needed for everyday use and is mainly relevant for specific legacy mobile or embedded display systems that still require WBMP input, where the original photo content matters less than simply having something display-compatible.

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