01 — The tool
Convert audio to MP3 or WAV with export settings
The free Loudness.ai Audio Converter opens a supported recording and saves it in MP3 or WAV format. Convert WAV to MP3 for a smaller listening file, or convert MP3 to WAV when an editor needs uncompressed audio. You can also open recordings such as M4A, FLAC and OGG.
Select the output quality, sample rate and channels rather than accepting a single preset. MP3 offers 128, 192 or 320 kbps; WAV offers 16-bit or 24-bit output. Listen to the source before converting, and keep it for later edits. Use the Audio Cutter first if you only need a short section.
02 — How it works
How to convert WAV, MP3, M4A and FLAC audio for free
Choose the source file
Open a supported recording and check that it plays correctly. The filename and waveform help you confirm you have selected the right take before changing its format.
Set the output format and quality
Choose MP3 or WAV, then select bitrate or bit depth. Pick 44.1 or 48 kHz and keep the original channels or choose mono, depending on where the file will be used.
Name and download the file
Enter a filename that distinguishes the converted version from the source. Export the audio, then check its playback and format in the app or editor that needs it.
03 — Practical uses
Choose an audio format for sharing and editing
WAV to MP3 for sharing
Use MP3 for a smaller file that is convenient to send or listen to. A higher bitrate generally keeps more detail but creates a larger download. Compare quality at the same playback volume.
MP3 to WAV for editors
Choose WAV when a video editor or audio project asks for it. Converting an existing MP3 changes its format; it does not recover detail already removed when the MP3 was originally created.
M4A and FLAC recordings
Convert M4A to MP3 for a common listening format, or FLAC to WAV for an editing workflow. Use the Stereo / Mono Converter if you need more control over channel routing.
04 — Frequently asked questions
Audio Converter questions
Can I convert any file to any audio format?
The tool reads audio formats supported by your browser and exports MP3 or WAV. It is designed for recordings such as MP3, WAV, M4A, FLAC and OGG, with the selected source format checked during loading.
Does converting to 24-bit WAV improve an MP3?
A 24-bit output provides a different storage format. It cannot restore sound detail lost through earlier lossy compression. Keep a high-quality original when you expect to make more edits later.
Which sample rate should I choose?
Use the rate required by your destination project. 44.1 kHz is common for music and 48 kHz for video workflows. Matching a project's settings can avoid another conversion during import.
Can I extract MP3 from a video?
Use Extract Audio from Video for an MP4 or WebM with sound. That tool reads the video's soundtrack and lets you export it as MP3 or WAV.
