Extract MP3 audio from MP4 video files
Videos are great for the screen, but audio is better for the road. Here is how I liberate the sound from my MP4 videos to create custom podcasts, music tracks, and offline lectures.
We are living in an era of video saturation. Everything is a video—from 3-hour educational lectures to deep-dive interviews. But our lives aren't always built for screens.
I recently found an incredible series of business lectures on my computer. I wanted to learn from them, but I couldn't find the time to sit in front of my monitor for 10 hours.
The solution was simple: Extraction.
I converted those MP4s into MP3s, put them on my phone, and "listened" to the lectures during my daily commute. I turned 10 hours of "screen time" into 10 hours of productive learning.
This is the Content Hack. It’s about making the content fit your life, not the other way around.
MP4 is a "container" that holds both video and audio. But often, the audio is the only part that matters.
Video files often contain sensitive information—your face, your home, or your proprietary screen recordings. You shouldn't have to upload those files to a "free" cloud converter just to get the audio.
Most online converters make their money by tracking your uploads or keeping copies of your data on their servers.
That’s why this tool is built to be a private workshop.
By using WebAssembly, we’ve brought the professional-grade FFmpeg engine directly into your browser tab.
If you're a YouTuber or a podcaster, use this tool to create "audio-only" versions of your videos for your members or your social media channels. It’s the fastest way to repurpose your hard work and reach your audience on the platforms they prefer.
Stop letting your content be trapped by the screen. Liberate your audio, keep your privacy, and build a library that moves with you.

Three reasons: Battery, Data, and Focus. Playing video uses significantly more battery and mobile data. Plus, if you're driving or working out, you don't need the visual distraction—audio-only lets you focus on the content.
Yes. Our tool is designed to extract the audio at the same quality as the original video stream. If you select a high bitrate like 256kbps or 320kbps, you won't lose any of the original clarity.
Absolutely. Our tool runs 100% in your browser. We don't have a server that 'sees' your video. Your data stays in your browser's memory and is never uploaded to a cloud. It's the most secure way to process video today.
Yes! Since the processing happens locally on your computer, we aren't limited by server upload caps. As long as your browser can handle the file size, our tool can process it.
