Extracting audio from any video file now is easier than ever when using a free online converter. With it, you don't need any software installed, no technical knowledge required, and it only takes a few steps – upload, select format, export, and download!
Nowadays, the MP4 video format is the go-to option, so it is the most plausible target for conversion. When it comes to audio, MP3 may be the most common format, but WAV and FLAC have their uses as well; they also affect the file size, bitrate, and audio quality of the result.
Audio formats explained
MP4 is a container that can hold video, audio, images, and subtitles, unlike audio formats, which store compressed sound data only. And before we proceed to how you can extract that sound, let's take a look at what types of audio files there are.
Although usually the intention is to listen to music, its format actually plays an important role in this and other purposes. Let's break down the most common ones:
- MP3 stands for MPEG-1 Audio Layer 3 and became the most common format for digital music because its lossy compression made files easier to store and share. It can play on almost any device, including Windows Media Player and Apple Music, though that compression may sometimes make the sound audibly worse.
- WAV stands for Waveform Audio File Format and is known for its high fidelity and large file size. It preserves audio in an uncompressed form, making it ideal for editing and archiving.
- FLAC means Free Lossless Audio Codec and provides lossless compression that preserves the original audio quality while reducing file size compared to WAV.
- OGG is a free, open-source audio format developed by the Xiph.Org Foundation. It provides good quality at lower bitrates but is less universally supported.
- AAC stands for Advanced Audio Coding and is a modern compressed audio format. It's widely used on Apple devices and usually sounds slightly better than MP3 at the same bitrate.
Of course, there are more audio formats, but these are the most usable in everyday Internet life. Also, it's not the only thing you should consider when working on audio; for example, sample rate also affects output fidelity, so check it in tools with advanced settings.

Upload an MP4 file
Open Clideo's Audio Cutter, click "Choose file" on the upload page, and pick the video from your device, cloud storage, like Google Drive or Dropbox.
Extract audio from video
When the audio track is added, the "Extract selected" option is chosen by default. It means that only the part inside the yellow markers will be saved. You can drag the markers to select the correct fragment, or enter the exact time in the boxes below.
"Fade in" and " Fade out" will make your audio start and end gradually.
"Delete Selected", on the other hand, allows you to cut out the middle section of the audio track and combine the parts before and after it. If you go with it, you may also tick "Crossfade" to make the transition between them smoother.
Convert video to an audio format
MP3 is the default option, but you can change it through the option on the bottom left under the player.
When you finish, click "Export".
Download the converted audio
After exporting, listen to the result and save it directly to your device or cloud storage. If you need to change something, click "Edit" to return to the editor.
Tips for conversion
Easy, isn't it? But such simplicity makes it all the more important to keep an eye on details that will make the output file perfect for your projects.
- Remember to match format to purpose. MP3 is the best for casual listening and sharing, and its universal support makes files easier to play and share with friends; WAV or FLAC matter for editing or archiving processes; OGG for open-source workflows, etc.
- Leave the part that you need only! In our Audio Cutter, you can easily trim and cut out any fragment of the file with great precision.
- Make sure the original video file has high-quality audio. Sometimes you can come across an MP4 clip with already over-compressed audio, in which case it's better to look for another audio source.
- Online tools are convenient for quick jobs, while desktop options are better for larger files or privacy-sensitive work.
Overall, it's all pretty intuitive and easy to follow, so you can go and try to convert your first MP4 to MP3!
MP3 uses lossy compression to reduce file size while maintaining acceptable sound quality, making it ideal for casual listening and sharing. WAV files are uncompressed, offering higher fidelity but resulting in much larger file sizes, which is better for editing and archiving.
Yes, many audio converters support batch conversion. For example, the online tool Convertio.co offers batch conversion capabilities directly in your browser, making it convenient for quick tasks without installing software. Additionally, there is a free desktop tool, like VLC Media Player, that supports batch conversion from video to audio formats.
Bitrate controls the amount of data processed per second in the audio file. Higher bitrates generally provide better sound quality but result in larger files. Some converters allow you to choose between Variable Bitrate (VBR) and Constant Bitrate (CBR) to balance quality and file size.
Online converters are convenient for quick tasks but often have file size limits and require uploading your files to their servers. For sensitive data or large files, offline desktop tools are safer as they do not require an Internet connection and minimize privacy concerns.
Yes, Clideo offers an Audio Converter mini tool that lets you adjust additional conversion settings, such as Audio Frequency and Audio Channels.
