What is a UAX file?

A .UAX file is an Unreal Audio Package. Game developers use these files to store sound effects, background music, and voice dialog for video games created with Unreal Engine. Companies like Epic Games, Gearbox Software, and the developers of Lineage 2 use this archive format to manage audio assets efficiently.

How to open UAX files?

Standard media players cannot play .UAX files directly because they are complex package files, not basic audio tracks. viewer.online/uax analyzes .UAX files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because the .UAX extension can occasionally apply to different game archive types, we recommend using viewer.online/uax to identify the actual format of your specific file.

Software and tools

If you want to edit or extract the audio data, you need specialized software. Developers typically open these packages using the Unreal Editor included with Unreal Engine. If you want to extract the internal audio files—which are often standard .WAV files—you can use community extraction tools like UModel (Unreal Model Viewer) or Dragon UnPACKer.

Summary

Because .UAX files use the known Unreal format, viewer.online/uax can safely open and display them online, eliminating compatibility problems.
