What is a MOFF file?
A .MOFF file is a Sony Video Data File created by Sony digital cameras and camcorders. It stores metadata, such as index data, date, time, and GPS coordinates, for an associated video file. It does not contain actual video content. Some systems also refer to it as a Media Offload File used by programs like Media Player Classic.
How to open MOFF files?
Because .MOFF files are companion files, standard video players do not open them directly. You can use Sony PlayMemories Home to manage and view the associated media. For manual inspection, you can open a .MOFF file in a basic text editor like Notepad++, though the data may appear as unreadable binary code.
Best practices and troubleshooting
Do not delete .MOFF files if you want to keep the metadata for your Sony videos. Always keep the .MOFF file in the same folder as the video file. Since it is not a video file, you cannot convert .MOFF to .MP4. However, you can convert the main video files to standard formats on convert.guru.
Software and tools
If you do not know the exact format of your file, viewer.online/moff analyzes .MOFF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
viewer.online/moff directly opens and previews .MOFF files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
