Convert BUN files online for free
The converter easily converts your BUN file to various formats - free and online. No Media Player or extra software needed.
The converter also works in reverse, so you can convert other Game formats to BUN with high quality output.
A .BUN file is essentially a digital shipping container - a proprietary archive format used to bundle thousands of smaller files into a single manageable block. While the extension is shared across different software ecosystems, you will most frequently encounter it as a Game Asset Bundle in titles from Electronic Arts (specifically the Need for Speed series) or engines like Unity. In these scenarios, the file acts as a locked warehouse containing textures, 3D models, and audio clips. A distinct, secondary use case exists within music production, where .BUN serves as a backup archive for Cakewalk (formerly SONAR) projects, bundling MIDI data and audio waveforms together.
The primary friction users face is that .BUN files are not designed for end-user access. You cannot simply double-click them to view the contents. They often employ proprietary compression or encryption schemes (like the compressed textures in NFS: Most Wanted or the UnityFS format) that standard tools like WinRAR cannot handle. This creates a barrier for modders trying to extract car skins or musicians trying to recover old projects without the original software installed.
For game assets, the pragmatic goal is extraction rather than direct conversion. You typically want to unpack the internal contents into standard formats: convert textures to DDS or PNG for editing in Adobe Photoshop, and extract audio streams to WAV or MP3. For Cakewalk users, the goal is often to recover the project to a CWP (project file) or extract the raw audio stems (WAV) for migration to a different DAW like Ableton Live. Using a specialized tool or convert.guru allows you to parse these containers and retrieve the usable media inside.

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 BUN converter.
