Extract text from osu! submitted beatmaps (OSZ2)
To convert OSZ2 beatmaps to another format, you need osu! or other Game software.
To convert other file formats to the "Encrypted Beatmap Archive" file type, you need software like osu! or a similar tool.
An .osz2 file is an encrypted beatmap archive used by the popular rhythm game osu!. It bundles audio tracks, background images, and gameplay beat timing data into a single downloadable package.
The format was developed by peppy to secure game assets, which makes it highly restrictive. Unlike the older OSZ format - which is merely a renamed ZIP archive - an .osz2 file is encrypted. This presents significant disadvantages: it is strictly proprietary, locks away the internal media, and cannot be opened by standard archive managers like WinRAR or 7-Zip. Users are forced to rely on the official game client just to access the files.
Typically, users want to extract or convert these archives into standard MP3 files for music playback, JPG or PNG files for wallpapers, and OSU text files to edit the beatmap manually.
Because .osz2 is a closed, encrypted format, standard online converters fail to process it. Often, only the original osu! software can properly decrypt and export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your OSZ2 file, detects the exact format, and lets you read the text inside.
If you want to convert OSZ2 file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use osu! or similar software from the "Game Beatmap Asset Storage" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to OSZ2, try osu! or another comparable tool in the "Game Beatmap Asset Storage" category.
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 OSZ2 converter.
