Convert a file to BIG

To convert other file formats to the "Game Data Archive" file type, you need software like Electronic Arts Games or a similar tool.


About BIG files

A .BIG file is a compressed game data archive primarily used by Electronic Arts to store bulk assets like audio tracks, 3D models, textures, and text. Secondary uses include virtual instrument sound banks for Avid Pro Tools via AIR Music Technology, and game archives for the Homeworld series by Relic Entertainment. To open or modify these files, gamers rely on community-built modding tools like Frosty Editor or FinalBig.

Users typically want to convert .BIG files to extract internal media for game modding or data mining. However, the format is highly proprietary, undocumented, and frequently exceeds multiple gigabytes in size. It acts as a locked container rather than a standard media file. You cannot natively browse it on Windows or macOS, and there is no official support from the developers for third-party editing.

Because it is an archive, you do not convert the .BIG file directly into a single format. Instead, the goal is to extract the contents into common targets like DDS or PNG for textures, and WAV or MP3 for audio.

This file format is exceptionally difficult to open or convert because standard tools lack the specific decoding algorithms for EA's custom compression. Often, only the original software or dedicated modding tools can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.

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

Users also converted BIN, ZIP, MP4, 7Z, EXE, RAR, PNG, CTR, PAZ and SAZ files.
