About Wireless Bitmap
Monochrome mobile graphics format.
About Portable Network Graphics
Pixel-perfect lossless output, clean alpha transparency, and strong support for screenshots, logos, and line art. Photographic images are usually much larger than JPEG or WebP; metadata and animation support vary by viewer.
Format referenceWhy convert WBMP to PNG?
- PNG is more appropriate for the target application, device, or delivery channel than WBMP.
- Compatibility is the main reason to convert when another person or service cannot open the source.
- The new format may support a feature the source container does not.
- The result can be reviewed without changing the file that other people still use.
Will quality change?
The PNG output stores decoded pixels without another lossy compression step. It cannot recreate detail the source already lost, and the file may be larger. Keep the source if you may need to adjust the conversion later.
Processing and limits
- Processing
- Browser first, server fallback
- Engine
- Browser Canvas or JavaScript, with server fallback
- Maximum size
- Server fallback accepts files up to 100 MB per file. Browser conversions are limited by available device memory.
- Batch support
- Yes, multiple files can be queued; completed results can be downloaded as a ZIP.
- Quality controls
- Options can adjust quality, output dimensions.
The browser attempts the conversion locally first. If the codec is unavailable or the file cannot be decoded, the server fallback handles it.
- Photographic images are usually much larger than JPEG or WebP; metadata and animation support vary by viewer.
- Review the converted file in the destination application before deleting the source.
- Batch results should be spot-checked before publication or delivery.
Platform compatibility
PNG works in all current major browsers. Open the result in the app where it will be used, and keep the source WBMP for comparison.
When not to convert
- Do not convert when the original WBMP must remain the only editable or archival copy.
- Skip the conversion when the destination already accepts WBMP and no compatibility problem exists.
- For a one-off preview, a local viewer may be faster than creating a new delivery file.
Frequently asked questions

- The browser attempts the conversion locally first. If the codec or file cannot be handled locally, the server fallback processes it over HTTPS and removes temporary data after the request.
- Is batch conversion supported?
- Queue multiple files, run them together, and download the finished results as a ZIP. Each server file is limited to 100 MB, and large batches may take longer.
- What can go wrong?
