WBMP was designed for the extremely limited graphics of early WAP mobile phones, while WebP was built by Google specifically for modern, fast-loading websites. Converting a legacy WBMP graphic to WebP is useful when that old mobile content needs to display properly on a current website, since browsers widely support WebP but have no native support for WBMP at all.
WebP's lossless mode preserves the exact bilevel image data without adding any color information that wasn't in the original source, since there's nothing in a WBMP file beyond pure black-and-white pixels to begin with.
- Install Batchify Image Converter and Resizer Pro on your Windows PC.
- Open the app and select Batch Mode for multiple files, or Individual Mode for a single WBMP.
- Drag your WBMP file or folder into the app window, enabling recursive folder scanning if needed.
- Set the "From" format to WBMP and the "To" format to WebP.
- Click Convert. WebP files are written to the output folder, fully offline.
- 100% offline — your legacy mobile graphics are never uploaded anywhere
- Bulk conversion of entire folders, including sub-folders, in one click
- Produces WebP files compatible with all current major browsers
- Multi-core processing for fast handling of large batches
- Option to delete original WBMP files automatically after conversion
- No recurring subscription or hidden upload limits
Do browsers support WBMP directly?
No, current browsers have no native WBMP support, which is why converting to a widely supported format like WebP is necessary for displaying legacy mobile graphics online.
Will converting to WebP improve image quality?
No, the original WBMP data only ever contained black-and-white pixels, so the converted WebP file displays the same content, just in a more web-friendly format.
Can I convert an entire folder of WBMP files to WebP at once?
Yes, Batch Mode handles entire folders, including nested sub-folders, and scales conversion speed across multiple CPU cores.
