Free online W64 to WV converter

Source format: W64

W64 is an audio file format based on the Wave64 specification, created by Sony to overcome the size limits of standard WAV files. It is used mainly in professional audio production, recording, and editing workflows where very large uncompressed audio files are common. Like WAV, W64 typically stores PCM audio and preserves high quality because it is usually lossless.

W64 is less common than WAV, so support can be limited in consumer players and some editors. It is most often encountered in studio environments, archival work, and applications that need files larger than the traditional 4 GB WAV limit.

Target format: WV

WV is the file extension for WavPack audio, a lossless compression format designed to reduce file size while preserving the original audio exactly. It is used by audio enthusiasts, archivists, and professionals who want smaller files without quality loss.

The main advantages of WV are smaller storage requirements, bit-perfect restoration of the source audio, and support for metadata. WV is useful for long-term storage, music libraries, and workflows where preserving original quality matters but disk space is important.

How to perform the conversion

The most reliable way to convert W64 to WV is with WavPack, the native tool for creating WV files. It is available for Windows, macOS, and Linux.

1. Install WavPack on your computer.
2. Open a terminal or command prompt.
3. Run a command such as wavpack input.w64.
4. The program creates a input.wv file in the same folder.

If you want to control compression level or preserve extra information, WavPack supports additional options. For example, you can use wavpack -hh input.w64 for higher compression, or consult the tool’s help output for metadata and tagging options.

If you prefer a graphical workflow, some audio editors can open W64 and export to WavPack, but support varies. In such cases, look for File → Export or File → Save as and choose WavPack or WV as the output format.

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

Notes on quality and compatibility

This conversion is lossless, so the audio quality does not change. The resulting WV file should decode back to the exact original PCM data stored in the W64 source.

Keep in mind that WV support is not universal. Many media players and editors can handle it, but some consumer devices and web tools cannot. If broad compatibility is more important than compression, WAV may be a safer delivery format.

Also note that if the W64 file contains unusual metadata, multichannel layouts, or non-PCM content, compatibility depends on the converter and the target application. For best results, verify the output in a WavPack-compatible player or editor after conversion.
