Found Old WBMP Files?

WBMP (Wireless Bitmap) was the image format of early mobile phones and PDAs. If you have these legacy files from the WAP era, most modern software cannot open them. Converting to BMP gives you a universally compatible format that works with every image editor.

BMP is the native bitmap format for Windows and works on virtually every platform. Once converted, you can edit, share, or further convert your images however you need.

How to Convert WBMP to BMP

  1. Upload your WBMP file - Drag and drop or click to select your wireless bitmap image
  2. Confirm BMP as output - BMP is selected by default for maximum compatibility
  3. Download your BMP - Your converted file is ready for use anywhere

The entire process happens in your browser. No software to install, no account needed.

WBMP vs BMP: Key Differences

Understanding what changes when you convert helps set expectations:

  • Color depth - WBMP is strictly 1-bit monochrome (black and white only). BMP supports up to 24-bit color (16.7 million colors)
  • Compression - WBMP uses minimal compression for small file sizes. BMP can be compressed or uncompressed
  • Software support - WBMP requires specialized viewers. BMP opens in Paint, Photoshop, GIMP, and every image application
  • Editing capability - WBMP is essentially read-only. BMP allows full editing with layers and effects

In our testing, WBMP files from old Nokia and early smartphone devices converted cleanly to BMP without any quality loss.

Common Use Cases

Recovering Legacy Mobile Images

Early 2000s mobile phones stored images as WBMP. If you are backing up old devices or found archived files, conversion to BMP lets you preserve and view these memories on modern systems.

Working with WAP Content

Developers maintaining legacy WAP applications sometimes need to extract and edit WBMP graphics. BMP provides a working format for these edits before converting back if needed.

Digital Archiving

For archival purposes, converting WBMP to BMP ensures long-term accessibility. BMP is a well-documented format that will remain readable for decades.

After Conversion Options

Once you have your BMP file, you might want to convert further depending on your needs:

  • BMP files can be converted to JPG for smaller file sizes and web use
  • For transparent backgrounds, convert your WBMP to PNG instead
  • If you need vector graphics, WBMP to SVG may be useful for simple black and white graphics

BMP serves as an excellent intermediate format for further processing.

Works on Any Device

Our converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • Tablets and smartphones

No plugins or downloads required. Your files stay on your device during conversion.

Pro Tip

WBMP files are already minimal in data. If you need to reduce file size after converting to BMP, consider converting to PNG which compresses black and white images very efficiently while remaining lossless.

Common Mistake

Expecting color to appear after conversion. WBMP is strictly monochrome by design. You will need to manually colorize the BMP in an image editor if color is needed.

Best For

Recovering and archiving images from legacy mobile devices, or extracting graphics from old WAP applications for editing or preservation.

Not Recommended

If you just need to view a WBMP file once and will not edit it, online WBMP viewers may be simpler than converting. For web publishing, convert directly to PNG or JPG instead of BMP.

Frequently Asked Questions

WBMP (Wireless Bitmap) is a monochrome image format created for early mobile devices and WAP (Wireless Application Protocol) browsers. It only supports black and white pixels with no grayscale or color, designed to minimize file size for slow mobile connections in the early 2000s.

No. The conversion preserves the original black and white appearance. WBMP files contain no color data, so the resulting BMP will also be black and white. However, you can then add color using image editing software since BMP supports full color.

No quality is lost. Both are bitmap formats that store pixel-by-pixel data. The conversion is lossless and your image will look identical in BMP format.

WBMP is an obsolete format that most modern image viewers do not support. It was designed for early mobile phones and PDAs. Converting to BMP gives you a universally compatible format that works with every image application.

Nearly every image program supports BMP including Microsoft Paint, Adobe Photoshop, GIMP, Paint.NET, Preview on Mac, and all modern photo viewers. It is the native Windows bitmap format with universal support.

Yes. Upload multiple WBMP files and convert them all to BMP in a single batch. This saves time when processing archives of legacy mobile images.

For archival and editing purposes, BMP is excellent as it preserves exact pixel data. For sharing or web use, PNG offers better compression and transparency support. Both are lossless formats.

No. The conversion happens entirely in your web browser using local processing. Your WBMP files never leave your device, ensuring complete privacy.

WBMP was used by early Nokia phones, Motorola devices, Palm PDAs, and other mobile devices from the late 1990s through mid-2000s that supported WAP browsing. The format is now obsolete.
