Convert WebM video and bitmap files (WBM) online for free
The converter easily converts your WBM videos and bitmaps to various formats - free and online. No VLC media player or other Video software needed.
The converter also works in reverse, so you can convert other "Web Video Container" formats to WBM without using software like VLC media player or a similar tool.
The .WBM file extension is most commonly associated with WebM video files or legacy Wireless Bitmap (WBMP) images. As a video file, it relies on the Matroska (MKV) container structure to deliver high-quality, compressed video primarily for web use. As an image file, it stores 1-bit monochrome data originally intended for early mobile phones over the Wireless Application Protocol (WAP). Other rare uses include audio project files for NCH WavePad.
Both primary formats have major limitations that require conversion. WebM videos are heavily optimized for web browsers but often fail to play natively on Apple devices, older smart TVs, or standard desktop media players without third-party tools like VLC media player. Wireless Bitmaps are entirely obsolete; they lack color support, transparency, and compatibility with modern image viewers.
You need to convert these files to make them usable in the modern ecosystem. For .WBM videos, convert to MP4 for maximum compatibility across smartphones, social media platforms, and video editors like Adobe Premiere Pro. For .WBM images, convert to PNG or JPG to open them on modern devices. Drop your file here to view and convert it securely right in your browser using convert.guru.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WBM converter.
