Convert Game saves and encrypted videos (FUN) online for free
The converter easily converts your FUN Game/video files to various formats - free and online. No Unity or or other Game software needed.
To convert other file formats to the "Serialized Game Save Data" file type, you need software like Unity or a similar tool.
The .fun file extension is heavily fragmented and used by various unrelated software applications. Most commonly, it serves as a serialized game save data file created by the Unity game engine or classic games like Super Princess Peach. In other contexts, it is an encrypted MP4 video file used by the 51cg Fun Player, an executable quiz file for Fun Test software, a disguised ZIP presentation package, or even a locked victim file encrypted by the Jigsaw Ransomware.
Because there is no universal standard for .fun, these files are incredibly frustrating to open and manage. They are proprietary and heavily dependent on the exact software that originally created them. Game saves are often locked binary or NET serialized data, meaning you cannot read or modify them with standard text editors. Encrypted video variations require specific, often outdated, media players and are entirely blocked by modern web browsers. Ransomware variants are completely inaccessible without a decryption key, and executable quizzes pose a major security risk if run blindly.
Conversion targets depend entirely on the file's true internal structure. For .fun files that are actually encrypted videos, converting them to standard MP4 or MKV restores playback on all modern devices. If the file is a disguised ZIP or PowerPoint game package, extraction to PPTX or standard folders is required. For game saves, converting the serialized data to JSON or XML allows modders and developers to safely edit the values. Drag and drop your file to analyze and convert it - free, online, and without installing software.
