Convert BK2 files online for free

The converter also works in reverse, so you can convert other Video formats to BK2 with high quality output.
The .BK2 file extension primarily represents the Bink 2 Video format, a proprietary video codec developed by RAD Game Tools (now part of Epic Games). It is the industry standard for in-game cutscenes, cinematics, and intro movies due to its high compression efficiency and low decoding overhead on CPUs and GPUs. Users typically encounter these files in the installation directories of PC games (e.g., \SteamApps\common\...\Movies).
The main challenge with .BK2 files is that they are not supported by standard media players like VLC or Windows Media Player without specific decoding libraries. Users often wish to convert them to share gameplay moments, edit cutscenes, or simply view game lore outside the game engine.
To open or convert these files, the most reliable method is the official, free RAD Video Tools. This utility allows you to view the files natively or convert them to common formats like MP4 (H.264), AVI, or WAV (audio only). While FFmpeg has added partial support for decoding Bink 2 in recent versions, the official RAD tools remain the gold standard for avoiding artifacts.

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 BK2 converter.
