Convert WebM exports to MP4

Built for users who need an MP4 file after exporting from AudioWave—especially when a destination platform does not accept WebM well.

Browser-only utility

Why this page exists

AudioWave currently exports video as WebM. Some editing and design tools require or work better with MP4 for uploading and editing.

This page gives you a clean conversion step without sending the source file back through our server.
