.WBMP file extension
To open .WBMP files on Windows, install ImageMagick (a tool that supports WBMP read/write).
To open a .wbmp file, use an image tool that supports WAP Bitmap (WBMP), such as ImageMagick. If your default photo viewer can’t open it, convert it to PNG or JPEG first.

How to open .WBMP files
Use these platform-specific instructions to open .WBMP files safely.
Windows
- Install ImageMagick (a tool that supports WBMP read/write).
- Convert the file to a common format, for example: magick input.wbmp output.png, then open the PNG in your normal photo viewer.
Mac
- Use ImageMagick to convert the file to a standard format (PNG/JPEG), for example: magick input.wbmp output.png.
- Open the converted image with Preview or another image viewer.
Linux
- Check that your desktop recognizes the type (often mapped as image/vnd.wap.wbmp by shared-mime-info).
- If it doesn’t open in your image viewer, convert it using ImageMagick: magick input.wbmp output.png, then open the PNG.
iOS
- iOS support for WBMP is not typically built-in; transfer the file to a desktop and convert it to PNG/JPEG with ImageMagick, then view it on iOS.
Android
- Android support for WBMP varies by app; if it won’t open, transfer the file to a desktop and convert it to PNG/JPEG with ImageMagick.
Security notes
- WBMP is an image format and is not meant to contain scripts or macros, but malformed image files can still trigger vulnerabilities in image decoders—avoid opening untrusted WBMP files in obscure/unknown viewers.
- Because WBMP is relatively uncommon, some apps may have less-tested parsers for it; converting with a well-maintained image tool (e.g., ImageMagick) and then viewing the converted PNG/JPEG can reduce exposure to niche decoders.
- Be cautious of files that only appear to be .wbmp by name; confirm the file is truly a WBMP image (and not a different file type renamed with .wbmp).
Can't open this file?
These are the most common causes and fixes when .WBMP files fail to open.
Common reasons
- It won’t open in my default photo viewer
- The image looks black-and-white or very low quality
- Linux file type detection seems wrong or the file has no association
Fix steps
- Convert it to a common format with ImageMagick (e.g., magick input.wbmp output.png).
- Open the converted PNG/JPEG in your usual photo app.
Recover a deleted or lost .WBMP file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

OS-specific troubleshooting
What is a .WBMP file?
WBMP (Wireless Application Protocol Bitmap) is a raster image format optimized for early mobile/WAP use. The WAP WAE specification defines WBMP types, including Type 0, which is black-and-white and uncompressed. On many systems it is identified as the MIME type image/vnd.wap.wbmp.
Background
WBMP comes from the early WAP (Wireless Application Protocol) ecosystem, where bandwidth and device resources were limited and simple black-and-white images were common. It was used to deliver small icons and graphics to WAP browsers and other mobile services of that era.
The WAP WAE specification defines the format and its types (including Type 0, a 1-bit-per-pixel black-and-white image). In practice today, WBMP is mostly encountered when working with legacy mobile content, telecom systems, or old device assets.
On modern desktops it’s relatively uncommon, so built-in photo apps may not recognize it. However, dedicated image-processing tools (notably ImageMagick) can read and write WBMP, making conversion straightforward when you need to view or reuse the image in modern contexts.
Common MIME types: image/vnd.wap.wbmp

Common .WBMP issues
It won’t open in my default photo viewer
WBMP is a legacy, niche monochrome format, and many modern viewers don’t include a decoder for it.
- Convert it to a common format with ImageMagick (e.g., magick input.wbmp output.png).
- Open the converted PNG/JPEG in your usual photo app.
The image looks black-and-white or very low quality
WBMP is typically 1-bit (monochrome) and was intended for early WAP devices; it may not contain grayscale or color information.
- Confirm this is expected: WBMP Type 0 is black-and-white (WAP WAE specification).
- If you need smoother edges, convert to PNG and apply image processing (scaling/antialiasing) in an editor after conversion.
Linux file type detection seems wrong or the file has no association
Desktop environments rely on the shared MIME database to map extensions to MIME types; local MIME caches or associations can be outdated.
- Verify it is being detected as image/vnd.wap.wbmp on your system.
- Update/refresh your MIME database (shared-mime-info) and re-associate the file type with a compatible image tool.
- If needed, bypass associations by converting with ImageMagick from the command line.
FAQ
What MIME type is used for .wbmp?
The registered media type is image/vnd.wap.wbmp.
Is WBMP always black-and-white?
The WAP WAE specification defines WBMP types; the commonly used WBMP Type 0 is monochrome (black-and-white) and uncompressed.
Can ImageMagick convert WBMP to PNG or JPEG?
Yes. ImageMagick lists WBMP support (read/write), so you can convert with a command like: magick input.wbmp output.png.
