Why extract audio from video locally?

Most online audio extractors upload your video to a remote server, process it in the cloud, and then make you wait in a queue. That exposes your files to third-party storage, adds upload/download delays, and often hides features behind a paywall.

Morphix runs FFmpeg compiled to WebAssembly directly in your browser. When you drop a video, the file stays on your device, the audio track is demuxed and re-encoded locally, and the resulting MP3 or WAV downloads straight to your computer. There is no upload, no signup, no watermark, and no daily quota — just fast, private audio extraction.

MP3 or WAV: which should I choose?

MP3 — compressed, small file size, plays on every device. Best for podcasts, music, ringtones, and sharing.
WAV — uncompressed, lossless quality, larger files. Best for editing, archiving, and professional audio work.
