Asked
Questions
What is MP4 format?
MP4 is essentially the go-to format for videos, which stores both digital video and audio together in a single container. This is why you see MP4 files everywhere, from YouTube clips to tutorials. MP4 files balance quality and file size well, so they’re easy to stream or share across devices. By choosing Flixier, the best MP4 to MP3 converter, you can upload MP4 files directly in your browser to convert or edit without any software installation.
What is the difference between MP3 and MP4?
Although their names sound similar, MP3 and MP4 serve different purposes. MP3 is strictly an audio format designed for compressing music or voice files. MP4, on the other hand, is a multimedia container that can include video, audio, subtitles, and more. If you want, for instance, to keep just the audio from a video, you’d convert an MP4 file into an MP3 with a fast browser-based video editor like Flixier.
How to convert MP4 to MP3?
Converting MP4 to MP3 means taking the audio track out of a video file and saving it as a separate audio file. You can do this with online tools or software that specialize in audio extraction, like Flixier. With Flixier, you can just upload your MP4, edit and export as MP3 – no installs, no waiting.
How to turn a video into an audio file?
Turning a video into an audio file is essentially the same as converting MP4 to MP3: you extract the sound from a video clip and save it as an audio file. This is useful if you want to listen to a podcast version of a webinar or save background music from a video for future use.
