Free online W64 to OGG converter

Source format

W64 is a Wave64 audio file format developed by Sony as an extension of standard WAV. It is used mainly in professional audio workflows where very large recordings are common, because it removes the 4 GB size limit of classic RIFF/WAV files. W64 is typically found in DAWs, audio editors, and recording systems that need to store long multichannel sessions or high-resolution audio without splitting files.

Target format

OGG usually means an audio file in the Ogg container, most often with Vorbis or Opus audio inside. It is a widely supported, open format that offers good compression and smaller file sizes than uncompressed audio. OGG is commonly used for music playback, streaming, games, and general-purpose distribution where efficient storage matters.

How to perform the conversion

The most reliable way to convert W64 to OGG is with FFmpeg, which supports both formats and preserves audio quality as well as possible during re-encoding.

1. Install FFmpeg on your computer if it is not already available.
2. Open a terminal or command prompt in the folder containing your .w64 file.
3. Run a command such as ffmpeg -i input.w64 -c:a libvorbis output.ogg to create an OGG Vorbis file.
4. If you want better compression and modern playback support, you can use Opus instead: ffmpeg -i input.w64 -c:a libopus output.ogg.
5. Check the resulting file in an audio player to confirm that the conversion completed correctly.

If you prefer a graphical editor, Audacity can open many WAV-like audio files, including W64 in supported builds, and export to OGG through File → Export → Export as OGG. This is useful when you want to trim, normalize, or edit the audio before saving it.

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

Notes on quality and compatibility

W64 is usually uncompressed, so converting it to OGG will always involve lossy compression if you choose Vorbis or Opus. That means the OGG file will be much smaller, but it will not be bit-for-bit identical to the source. For archiving or mastering, keep the original W64 file; for playback and sharing, OGG is often a good choice.

Compatibility is generally good for OGG Vorbis, though some devices and older players may support it less consistently than MP3 or AAC. Opus offers excellent quality at low bitrates, but not every legacy player handles it well inside an OGG container. If maximum compatibility is important, test the output on your target devices before distributing it.
