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 modern AVIF image, which can support up to 12-bit color depth, directly to WBMP represents a dramatic reduction, collapsing all of that color and tonal data down to pure black-and-white pixels.
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 image's quality matters less than simply having something display-compatible.
- Install Turbo Batch Image Converter Pro on your Windows PC.
- Open the app and select Batch Mode for multiple files, or Individual Mode for a single AVIF file.
- Drag your AVIF file or folder into the app window, enabling recursive folder scanning if needed.
- Set the "From" format to AVIF and the "To" format to WBMP.
- Click Convert. WBMP files are written to the output folder, fully offline.
- 100% offline — your images are never uploaded anywhere
- Bulk conversion of entire folders, including sub-folders, in one click
- Produces standard 1-bit WBMP files for legacy mobile and embedded systems
- Multi-core processing for fast handling of large batches
- Option to delete original AVIF files automatically after conversion
- No recurring subscription or hidden upload limits
Why does my converted WBMP look so different from the original AVIF?
WBMP is a strictly black-and-white, 1-bit-per-pixel format with no grayscale or color support, so all the color and detail from your AVIF image is reduced to pure black or white pixels.
What devices or systems use WBMP today?
WBMP was designed for early WAP mobile phones and is now mainly relevant to specific legacy mobile or embedded display systems that still expect this format.
Will my image still be recognizable after converting to WBMP?
High-contrast graphics with clear shapes tend to convert more recognizably than detailed images with subtle color variation, since WBMP has no way to represent intermediate shades.
