02
Or choose a file from your device

Local files stay in your browser and take priority over a link.

MP4, WebM, M4A, MP3, WAV, OGG, MOV or AAC · up to 100 MiB

Higher bitrates use more space. They cannot restore detail missing from the source.

Ready when you are.

How to use the youtube to mp3

Create an MP3 audio file from media you are permitted to download and convert. Resolve a single public YouTube video, choose an available stream, and convert its audio, or select a local media file directly. Choose a target bitrate of 128, 192, 256, or 320 kbps; 192 kbps is the default. Video frames are omitted, leaving an audio file that you can download to your device.

Conversion runs in your browser using ffmpeg.wasm. The conversion engine is loaded when needed and is much larger than this page’s interface. Local files stay on your device. For YouTube input, a separate extraction worker resolves supported public streams and relays the selected media through the server; that transfer still uses server bandwidth. The worker does not store downloaded media files.

Input is limited to 100 MiB. Public videos must be non-live and no longer than fifteen minutes; local conversion keeps only the first fifteen minutes. Each conversion has a two-minute processing limit. Smaller files are more practical on phones or devices with limited memory. Choose a shorter source if the browser runs out of resources or the job cannot finish within the limit.

Frequently asked questions

Why might a YouTube URL fail?

YouTube can restrict automated access or change its delivery formats. Private, account-required, age-restricted, region-restricted, live, and unsupported streams are not bypassed by this tool. If extraction is unavailable, convert a local file that you already have permission to use.

Does conversion improve the original quality?

No. Transcoding cannot recover detail missing from the source and can introduce additional loss. Output format and bitrate affect compatibility and size, but a larger file does not necessarily contain better audio or video.

Can I convert without uploading a file?

Yes. Select a local file and convert it in the browser. The engine loads from this website, but the selected file is not uploaded. Download the result before closing the page, because conversion output is not stored as an account library.
