WEM to WAV Free Online Conversion

Convert WEM audio files to WAV format. Processed directly in the browser without uploading to a server, ensuring your file privacy and security.

WEM

The WEM format is created by the Wwise professional audio engine, typically used for game and video BGM music.

Because WEM uses a special encoding scheme, WEM files extracted from games cannot be opened with regular music players; they require format conversion or a decoder plugin to play.

WAV

WAV and AIFF are compatible with Microsoft, macOS, and Linux operating systems. Note that WAV files are not completely equivalent to lossless files; WAV simply does not compress the original file.

If the source file is lossless, WAV can be called a lossless file. If a lossy compressed file (e.g., MP3) is converted to WAV, the WAV file only faithfully represents the lossy file.

How does it work?

When you drag one or more .wem files into the page, the underlying WebAssembly decoding module decodes Wwise proprietary WEM format to standard PCM data and packages it into .wav files in the browser. The entire process does not go through a server; all computation is done locally.

Conversion speed

Conversion speed depends on the bit rate of the WEM file—the higher the bit rate, the better the WAV file quality but the larger the file size.

Conversion quality

This tool strictly repackages the original PCM data according to WAV specifications, preserving 100% of the original audio quality with no additional compression or resampling, suitable for editing, mixing, or archiving.

Supported browsers?

Supports all modern browsers, including Chrome, Firefox, Safari, and Edge.

Do I need to pay?

This tool is completely free, no registration or login required, and all conversion processes are done in the local browser.
