About OSK files

An .OSK file is a game skin package used by osu!, a popular free-to-play rhythm game developed by peppy. These files allow players to customize the game's interface, including cursors, hit circles, and audio effects. While .OSK files are technically standard ZIP archives, their unique extension is designed to automatically trigger the osu! importer when double-clicked. This creates a drawback for users who wish to view, edit, or extract specific assets (like PNG images or WAV sound files) without launching the game. Additionally, users on mobile devices or computers without osu! installed often cannot open these files to preview the content. For editing or resource extraction, the best workflow is to convert the .OSK to ZIP, which makes the internal skin.ini configuration and media folders accessible to any operating system.

Convert.Guru analyzes your OSK file, detects the exact format, and lets you read the text inside.

Users also converted ZIP, RAR, OSU, PNG, OSZ, CUR, 7Z, WEBP, HIF, FLP, CDW, TSX and OSB files.
