ASF to W64 Converter

Convert ASF files to W64. Free, without uploading.

This tool converts ASF files to W64. Advanced Systems Format.

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