F4V to W64 Converter

Convert F4V files to W64. Free, without uploading.

This tool converts F4V files to W64. Flash MP4 video.

Sony Wave64 (large WAV). Only the audio of the F4V video is kept and saved as W64; the picture is dropped. W64 is lossless, so the audio keeps the quality it has in the F4V 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 F4V 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.
