About OSZ files
An .osz file is the standard distribution package for osu!, a popular free-to-play rhythm game developed by ppy. While these files are essential for gameplay, they often cause frustration for users who simply want to access the music or artwork contained within.
Because the .osz extension is proprietary to the game, standard media players like VLC or Windows Media Player cannot open them directly. This creates a catch where users download a 20MB+ file just to listen to a song, only to find the file is 'locked' in an unrecognizable format. In reality, an .osz file is simply a standard ZIP archive in disguise.
For Web and Personal Use, the best workflow is to 'convert' the file by renaming the extension from .osz to zip. This allows you to open it with 7-Zip or WinRAR to extract the source MP3 or OGG audio files and JPG background images without installing the game. For Editing, the internal osu files are plain text documents that can be modified in Notepad++ to adjust beatmap difficulty or timing.
Convert.Guru analyzes your OSZ file, detects the exact format, and lets you read the text inside.

The OSZ Converter Story
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 OSZ converter.
