Converting MP4 to MP3 in practice
MP4 to MP3 keeps only the soundtrack and throws away the picture — exactly what you want when the audio is the whole point. A recorded lecture, an interview, a song trapped in a music video, or a podcast someone published as video all become a small audio file you can play anywhere, at a fraction of the original size.
The honest part most converters skip: the MP3 can never sound better than the audio already inside the MP4. If the video’s sound is 128 kbps, asking for “320 kbps” just inflates the file with nothing you can hear. For a phone, a car deck, or a Bluetooth speaker the extracted track is indistinguishable from the source. Pull it on Wi-Fi and it plays through the commute with no data and no app attached.

About the MP4 and MP3 formats
MP4
MP4 (MPEG-4 Part 14) is the most widely supported video container on the planet. It packs H.264 or H.265 video with AAC audio into a single file that plays natively on iPhone, Android, Windows, macOS, web browsers, smart TVs, and every modern editor. Use MP4 when you need a finished, shareable video that will just work, anywhere, without re-encoding.
MP3
MP3 is the most compatible audio format ever made. It plays on every device built in the last 25 years, from a $5 Bluetooth speaker to a Tesla, and 320 kbps MP3 is sonically indistinguishable from CD for most listeners. Pick MP3 when you want a file that will simply play, everywhere, without anyone asking what a codec is.

MP4 to MP3 — Frequently asked questions
We encode at 320 kbps constant bitrate by default — the highest bitrate MP3 supports. It cannot add quality the MP4 never had: a video with 128 kbps audio gives a 320 kbps file that sounds the same as its source, just larger. For a smaller file with the same sound, pick a lower bitrate on the home page.
A small, usually inaudible loss occurs because MP3 is lossy. Going from the AAC audio inside an MP4 to 320 kbps MP3 is what audio engineers call transcoding — fine for listening, but not ideal for further editing. Use WAV or FLAC for editing.
The web interface converts the whole file. To trim, use a free audio editor like Audacity after downloading the MP3, or feed the MP4 to a video trimmer first.
320 if you want the cleanest result, but understand what it does. The audio inside an MP4 is normally AAC that was already compressed once, so this is a second compression on top. A high bitrate limits how much more is lost; it cannot recover anything the first pass discarded. Picking 320 on a quiet phone recording just makes a larger file.
Yes — a lecture, a set, a three-hour stream all convert. Only the audio is decoded, so length costs time rather than failing, and the resulting MP3 is a fraction of the video's size.
Free, no account, up to 60 conversions an hour, up to 2 GB (4 GB signed in). Your file is virus-scanned (a video or audio result over 1 GB, or one whose scan times out, is delivered unscanned and says so), converted, handed back on a private link and deleted after two hours (longer for results over 2 GB or with a Pro pass) — including the video you uploaded.
