Free online WAV to W64 converter

Source format: wav

WAV is a widely used audio container format developed by Microsoft and IBM. It is most commonly associated with uncompressed PCM audio, although it can also store some compressed audio codecs. WAV files are used by musicians, sound engineers, podcasters, video editors, and general computer users because they are broadly compatible and preserve high audio quality. Typical uses include recording, editing, archiving, and exchanging audio between applications.

Target format: w64

W64 is an audio file format designed as an extension of WAV for very large files. It is commonly associated with Sound Forge and other professional audio tools. The main advantage of W64 is that it supports files larger than 4 GB, which is a limitation of standard WAV in many workflows. This makes W64 useful for long recordings, multichannel sessions, and high-resolution audio projects that would otherwise exceed WAV size limits.

How to perform the conversion

The easiest way to convert WAV to W64 is with a professional audio editor that supports both formats, such as Sound Forge or Adobe Audition if W64 export is available through installed codecs or plug-ins. If you want a simple no-install option, you can convert the file on 101convert.com for free.

1. Open the .wav file in your audio editor.
2. Check whether the audio is already in the desired sample rate, bit depth, and channel layout.
3. Choose File → Save As or File → Export.
4. Select W64 as the output format.
5. Set the output name, for example audio.w64.
6. Confirm the export and wait for the conversion to finish.

If your software does not offer W64 directly, try a dedicated audio editor that supports professional broadcast formats. In some workflows, FFmpeg may be able to remux or convert audio into W64-compatible containers depending on build support, but desktop audio editors are usually the most reliable choice for this specific conversion.

Notes on quality and compatibility

Converting WAV to W64 does not improve audio quality by itself. If the source is uncompressed PCM, the audio data can remain unchanged; only the container format changes. The main reason to convert is compatibility with very large files. Keep in mind that W64 is less universally supported than WAV, so some consumer players and editors may not open it. If broad compatibility is important, keep a WAV copy as well. Also, if the source WAV is already under 4 GB and does not need W64-specific features, staying with WAV is often the safer choice.
