About MP4intoMP3

We built MP4intoMP3 because every other "MP4 to MP3" site treated users like a product — throwing aggressive ads, locking quality behind paywalls, capping file sizes, and uploading personal videos to unknown servers. We thought it could be done better.

Our mission

Make a free, private, professional-grade MP4 to MP3 converter that anyone can use, on any device, without ever sending their files to a server. The audio you extract should be your audio — full quality, full speed, full control.

How we keep it free

Unlike most converter sites, we don't pay for expensive servers because conversion happens entirely in your browser. That keeps our running costs near zero, which means we can offer the service free to everyone, forever, supported only by a small amount of non-intrusive advertising.

Privacy first

We don't ask for your email. We don't track you across the web. We don't even see the videos you convert — they never leave your device. The only data we use is anonymous aggregated traffic information to keep the site reliable.

Who we serve

Podcasters, musicians, students, journalists, audiobook lovers, language learners, content creators — anyone who has an MP4 video and wants the audio out of it, fast. We've optimized every part of the experience for them.
