Convert MP4 to M4A

M4A often gives you better sound quality than MP3 at the same file size. It's particularly good for music and high-quality voice recordings, preserving more detail in the audio. If you're extracting audio from music videos, concerts, interviews or podcast recordings, M4A maintains more of the original audio quality. It also supports advanced features like chapters and embedded images that MP3 doesn't, which is great for audiobooks or podcast episodes.

Most modern devices handle M4A files beautifully - they work perfectly on iPhones, iPads, and Macs (Apple actually prefers this format), and they play well on most Android devices and modern Windows media players too. Even smart speakers like Amazon Echo and Google Home support them. If you have very old devices, you might occasionally run into compatibility issues, but for most up-to-date equipment, M4A works seamlessly.

The difference is dramatic! By extracting just the audio, a typical 300MB video might become a 15-20MB M4A file - that's less than 10% of the original size. This makes M4A perfect when you just need the audio portion for listening on the go, saving storage space on your phone, or creating a music library from video content. The exact space savings depends on the video quality and audio complexity, but it's always substantially smaller.

Absolutely! Our converter lets you choose the perfect balance between quality and file size. The "standard" setting (128kbps) works well for most content like podcasts and general music. For high-quality music extraction, bump it up to "high quality" (256kbps) to preserve more audio detail. If storage space is very limited or you're just extracting speech content, the "compact" setting (96kbps) creates even smaller files that still sound good for voices.

Yes! Our converter preserves existing metadata from the MP4 file and lets you add or edit information during conversion. You can add custom track titles, artist names, album information, genre tags, and even cover artwork. This is especially useful when building a music library from video files - your extracted audio will appear with all the right information in music players and media libraries without needing additional editing afterward.
