Videos are heavy and distracting. Here is how I liberate the sound from my MP4, WebM, and MOV files to create a personalized library of podcasts, lectures, and memories.
We live in an age where everything is a video. But let’s be honest: most of the "value" in a video is usually in what is being said, not what is being shown.
I realized this when I looked at my hard drive. I had gigabytes of "Saved" lectures, "Watch Later" interviews, and recorded meetings. They were taking up massive amounts of space and—more importantly—they were taking up massive amounts of my "focus time."
I decided to stop "watching" and start "listening."
I began extracting the audio from every video I wanted to consume. I turned my 1GB business lectures into 50MB MP3s. I turned my private meeting recordings into lightweight voice notes.
This is the Audio-Only Manifesto. It’s about reclaiming your time, your focus, and your storage.
Your videos are your life. They contain your face, your home, your children, and your professional secrets. You shouldn't have to sacrifice that privacy to get a usable audio file.
Most "free" online converters make their money by harvesting your data or keeping copies of your files on their servers.
That’s why this tool is built to be a private workshop.
By using WebAssembly, we’ve brought the world’s most powerful media engine directly into your browser tab.
If you’re a creator, don't just "upload video." Repurpose your work. Extract the audio from your tutorials and share them as private podcasts for your community. Extract the audio from your live streams and turn them into voice notes for your newsletter. It’s the fastest way to multiply your impact without doubling your work.
Stop letting your audio be trapped by the pixels. Liberate your sound, keep your privacy, and build a library that moves with you.
