Frequently Asked Questions

Everything You Need to Know

How do I remove the audio track from an MP4 video online?

Drop your MP4 file into ClipShrink. Our client-side WebAssembly engine strips the AAC or MP3 audio track and saves a silent MP4 in under 0.1 seconds with zero cloud uploads.

Does removing audio make the MP4 file size smaller?

Yes! Discarding the audio stream reduces the file size by the weight of the audio track (typically 1MB to 10MB depending on audio bitrate and length).
