MP4 to W64 Converter

Convert MP4 files to W64. Free, without uploading.

This tool converts MP4 files to W64. MP4 is the most widely used video format. It usually holds H.264 video and AAC audio and plays on phones, browsers, TVs and social networks.

Sony Wave64 (large WAV). Only the audio of the MP4 video is kept and saved as W64; the picture is dropped. W64 is lossless, so the audio keeps the quality it has in the MP4 file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the MP4 video, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the W64 file.
