The fastest way to convert YouTube to MP3
YouTubeToMP3X turns any YouTube video into a clean MP3 file in under a minute. Paste a link, switch to the Audio (MP3) tab and pick a bitrate from 64 to 320kbps. Our server extracts the original audio stream from the video and converts it once with FFmpeg, no screen recording, no re-compression, no watermarks and no bundled software. It works in any browser on Windows, Mac, Linux, iPhone and Android.
Which MP3 bitrate should you choose?
The right bitrate depends on what you are converting. YouTube itself stores audio at roughly 128-160kbps (AAC/Opus), so a 320kbps MP3 preserves everything the source has while a lower bitrate saves space:
MP3 mode: the four bitrates, each with an estimated file size before you commit to anything.
- 320kbps, music and critical listening. Maximum quality, ~140 MB per hour. Music lover? Use the dedicated 320kbps converter.
- 256kbps, everyday music listening with smaller files.
- 128kbps. Podcasts, interviews, lectures. Speech stays perfectly clear at ~56 MB per hour.
- 64kbps. Voice memos and audiobooks when storage is tight.
Wondering whether 320kbps is worth it? Our honest breakdown: YouTube to MP3 at 320kbps, what you actually get.
Tested on the live converter
Numbers from an actual conversion run on this site on 22 August 2026, measured with
ffprobe, not estimates. Source: “Big Buck Bunny 60fps 4K, Official Blender
Foundation Short Film” (Creative Commons Attribution licence), converted in full at
128kbps.
- Source length: 10 minutes 34 seconds
- Quality chosen: 128kbps MP3
- Time from pressing Download to the file being ready: 27 seconds
- Resulting file: 10,194,738 bytes (9.7 MB)
- Output: MP3, 48kHz, stereo, measured at exactly 128kbps
A full ten-and-a-half-minute track took under half a minute, so a typical three-to-four minute song finishes in well under that. Longer videos take proportionally longer. The file has to be fetched and encoded before your download starts, which is why you see a progress bar rather than an instant link.
If you specifically want maximum bitrate, our 320kbps converter has the full 64/128/256/320 comparison with measured file sizes and encode times.
Why people use a YouTube to MP3 converter
- Podcasts that only exist as video, take them on your commute without burning mobile data.

Only need a clip? Our YouTube to MP3 cutter lets you trim just the section you want, great for ringtones.
YouTube to MP3 vs YouTube to MP4
Only need the sound? MP3 gives you a far smaller file that plays in every music app. Want the picture too? Use our YouTube to MP4 converter for video up to 1080p, or the all-in-one YouTube downloader that lets you pick either on one page. For Shorts there is a dedicated Shorts downloader, and whole playlists are handled by the playlist downloader.
How we keep quality high
Many converters decode and re-encode audio several times, which stacks compression artefacts. We download the highest-quality audio stream YouTube offers, convert it exactly once and deliver the file directly, with a live progress bar so you always know what is happening. Read more in our guide on how to extract audio from a YouTube video.
Please convert only audio you have the right to save: your own uploads, licensed content, or Creative Commons material. This educational tool is not affiliated with YouTube. See our post on the legality of downloading YouTube videos.
