Free online WV to W64 converter

Source format: WV

WV is the file extension for WavPack audio files, a lossless compression format used to store high-quality audio with no data loss. It is popular among audio enthusiasts, archivists, and users who want smaller files without sacrificing original sound quality. WV files are often used for music libraries, backups of master recordings, and audio preservation workflows.

Target format: W64

W64 is the Wave64 audio container format, an extension of the standard WAV format designed to overcome the 4 GB size limit of classic WAV files. It is commonly used in professional audio production, long recordings, and high-resolution audio projects where very large uncompressed files are needed. Its main advantage is compatibility with large audio data and support for long-duration, high-bitrate recordings.

How to perform the conversion

The most practical way to convert WV to W64 is with a desktop audio tool that supports both formats, such as ffmpeg or a dedicated audio editor/converter. If you want to convert online, you can use the built-in converter on 101convert.com for free without installing any software.

Using ffmpeg:

1. Install ffmpeg on your computer.
2. Open a terminal or command prompt in the folder containing your WV file.
3. Run a command such as ffmpeg -i input.wv output.w64.
4. Wait for the conversion to finish, then open the resulting W64 file in a compatible audio editor or player.

Using a GUI audio editor:

1. Open the WV file in software that can read WavPack and export Wave64.
2. Choose File → Save As or File → Export.
3. Select W64 or Wave64 as the output format.
4. Confirm the export settings and save the file.

Notes on quality, compatibility, or limitations

This conversion is usually lossless in terms of audio content only if the source is decoded and written to an uncompressed format without additional processing; however, moving from WV to W64 typically means converting from a compressed lossless format to an uncompressed container, so the file size will increase significantly. The audio quality itself should remain unchanged if no resampling, normalization, or effects are applied.

Compatibility is the main limitation: W64 is not as universally supported as standard WAV, so make sure your target software can open Wave64 files. If broad compatibility is important, consider whether WAV may be a better target than W64. Also, because W64 is uncompressed, the resulting files can be very large, especially for long or multichannel recordings.
