What to expect

  • WBMP is a legacy mobile format with limited software support; convert to PNG for everyday viewing and sharing.

Frequently asked questions

What happens to my PNG when it becomes a WBMP?
WBMP is a wireless bitmap format designed for early mobile devices and stores a 1-bit monochrome image. Colour and grayscale detail from the PNG are reduced to pure black and white.
Why would I convert a PNG to WBMP?
WBMP was created for low-bandwidth wireless (WAP) contexts, so the format is chosen when a legacy mobile system or tool specifically requires a wireless bitmap rather than a modern image format.
Where can I open a WBMP file?
Support is limited to a handful of image tools such as GIMP, IrfanView, and XnView; it is not a format modern browsers or default viewers show. For general use, convert back to PNG.
Is any colour kept in the WBMP?
No. WBMP is monochrome (1-bit), so the output is strictly black and white with no colour or grey tones, typically produced by thresholding the PNG.
