Image to WBMP Converter

WBMP, the Wireless Bitmap, is a throwback to the early mobile web. It stores images in a single bit per pixel, meaning pure black and white with no greys and no colour, and it was designed for the tiny monochrome screens of WAP phones around the turn of the millennium. The format is almost vanishingly rare today, surviving mainly in legacy mobile systems and the odd embedded display.

Converting to WBMP is a niche job that comes up only when you genuinely need a one-bit monochrome image for old WAP content or a simple monochrome device. Because the format throws away all colour and shading, results look best from high-contrast source graphics rather than photographs. Far more often, the useful direction is converting a WBMP out to PNG, so the image can be viewed and edited in modern software that no longer recognises the old format.

Our WBMP converter handles these conversions in the browser with no account and no watermark, processing single files or batches with individual or ZIP downloads. It is the practical tool for the rare moment you have to produce or read a wireless bitmap, with everything done on your own device. For anything modern, converting to PNG or JPEG instead will serve you far better.
