How to Convert YouTube to MP3

Paste a YouTube URL into the box above. TubeMixLab looks up the video's title, channel and thumbnail, then downloads and converts the full audio track to an MP3 — 320kbps or 128kbps, your choice — you can preview and download, no account required.

Full-Video Conversion vs. Trimming a Specific Segment

This converter exports the entire video's audio. If you only want a portion of it — a specific verse, a quote, a highlight — use the YouTube Audio Cutter instead, which lets you set an exact start and end time before exporting.

When to Use the TubeMixLab Mixer

Need audio from more than one video in a single file? The YouTube MP3 Mixer combines multiple trimmed clips — in any order, with fades and volume control — into one MP3.

MP3 Audio Quality

Choose 320kbps for the best quality, or 128kbps for a smaller, faster download — the toggle sits right above the Convert button. There's no re-encoding step after export either way, so the file you download is the one TubeMixLab produces directly from the source audio at whichever bitrate you picked.

If you'd rather not compress it at all, the format toggle next to it offers FLAC and WAV. YouTube stores its audio already compressed (Opus or AAC), so an MP3 conversion is a second pass of lossy compression on top of that; FLAC and WAV keep exactly what comes out of decoding the source instead. They can't recover detail YouTube's own encoder discarded — nothing can — but they don't discard any more, which is what you want when the file is headed into a DAW or an archive. The tradeoff is size: expect roughly 3x a 320kbps MP3 for FLAC and 5x for WAV, which is why lossless conversions are capped at 40 minutes.

YouTube to MP3 on Desktop and Mobile

The converter runs entirely in your browser, so the same tool works on desktop and mobile without installing an app. Paste a link, wait for the preview to load, then download — the page layout adapts to smaller screens automatically.

Convert YouTube Audio for an MP3 Player

The MP3 you download is a standard, unlocked file — no proprietary format and no DRM. Copy it to a phone, a computer, or a dedicated MP3 player the same way you would any other MP3 in your library, and it'll play the same on all of them.

If you'd rather listen right away than download first, the YouTube MP3 player queues several videos and plays them as audio in the browser, with a download button on every track.

Frequently Asked Questions

Is this YouTube to MP3 converter free?

Yes, converting a video to MP3 is free and doesn't require an account.

Can I convert only part of a YouTube video to MP3?

Yes — use the YouTube Audio Cutter to select an exact start and end time before exporting, instead of converting the full video.

What audio quality does the converted MP3 use?

You choose — 320kbps for the best quality, or 128kbps for a smaller file, using the toggle above the Convert button. It defaults to 320kbps. The bitrate only applies to MP3 — FLAC and WAV are lossless, so there is no bitrate to choose.

Can I download WAV or FLAC instead of MP3?

Yes — pick FLAC or WAV in the format toggle above the Convert button. YouTube's audio is already compressed, so converting it to MP3 compresses it a second time; FLAC and WAV skip that step and keep exactly what came out of the source. Neither makes the audio better than YouTube's own — they just stop anything more being thrown away, which matters if the file is going into a DAW or an archive. FLAC runs around 3x the size of a 320kbps MP3 and WAV around 5x, so lossless conversions are capped at 40 minutes — longer videos have to be converted as MP3.

Do I need to install any software?

No. Everything runs in your browser and on TubeMixLab's servers — there's nothing to download or install to use the converter itself.

Can I convert YouTube audio for an MP3 player?

Yes. The exported file is a standard MP3, so you can transfer it to a phone, computer or any MP3-compatible player just like any other MP3 file.
