About this tool
This is an audio converter: it takes a WAV, M4A, OGG or FLAC file — or the sound from a video — and gives you back an MP3. MP3 is the format every player, phone, car stereo and podcast tool accepts, which makes it the right target when you want the sound and not the picture.
How to convert audio to MP3
- 1.Choose the video or audio file.
- 2.Pick the bitrate — higher means better quality and a bigger file.
- 3.Press Run and wait for the job to finish.
- 4.Download the MP3.
When people use it
Listening instead of watching
Turn a recorded talk or interview into something you can play in the car or on a walk.
Podcast and audio workflows
Most podcast tooling expects MP3. Converting once at the start avoids format arguments later.
Saving space
Audio-only is a fraction of the size when you never needed the video in the first place.
What it will not do
Worth knowing before you upload, rather than after.
- MP3 is lossy, so converting from another lossy format loses a little more each time.
- The picture is discarded entirely — this returns audio only.
- A video with no audio track will fail, because there is nothing to extract.
Questions
What bitrate should I choose?
192 kbps is a good default for speech and most music. Use 128 kbps for spoken word where size matters, or 256 kbps when you want to preserve more detail.
Can I convert MP4 to MP3?
Yes — that is exactly what this does. Upload the MP4 and you get the audio back as an MP3, with the video discarded.
Does this work on audio files too?
Yes. WAV, M4A, OGG and FLAC can all be converted to MP3.
Is it free?
Free, no account, no watermark, up to 100MB.
What happens to my file?
Your upload goes to private storage that is never public and never listed, and only the anonymous session that created the job can read it. The original file is deleted as soon as processing succeeds. The result stays available for about 90 minutes, and you can delete everything immediately with the Delete now button.
