Free online WMA to W64 converter

Source format: WMA

WMA stands for Windows Media Audio, an audio format developed by Microsoft. It is commonly used for music tracks, voice recordings, and older Windows-based media libraries. WMA files may be lossy or, less commonly, use variants designed for higher fidelity. They are often found in legacy collections, Windows Media Player libraries, and older portable devices.

Target format: W64

W64 is a 64-bit audio container format used mainly by professional audio software. It is designed to overcome the size limits of standard WAV files and can store very large recordings, making it useful for long sessions, multichannel audio, and high sample-rate projects. W64 is supported by some DAWs and audio editors, especially in post-production and archival workflows.

How to perform the conversion

The most practical way to convert WMA to W64 is with a desktop audio tool that can read WMA and export W64, such as FFmpeg or a professional audio editor that supports both formats.

Using FFmpeg

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt.
3. Run a command like ffmpeg -i input.wma output.w64.
4. Check the resulting file in your audio software to confirm it opens correctly.

Using an audio editor

1. Open the WMA file in an editor that supports WMA import and W64 export.
2. Choose File → Save As or File → Export.
3. Select W64 as the output format.
4. Save the converted file and verify playback.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality and compatibility

Converting WMA to W64 does not improve audio quality; it only changes the container or encoding format. If the source WMA is lossy, the converted file will still contain the same lossy audio data. W64 is excellent for large files, but it is less universally compatible than WAV, so make sure your target software supports it before converting. If your goal is simple playback or sharing, WMA may be more convenient; if your goal is editing or archiving large audio projects, W64 is a better fit.
