How to Mix YouTube Clips
Paste a YouTube link into the box above and TubeMixLab pulls in the title, channel and thumbnail automatically. Add as many clips as you need — from the same video or different ones — then repeat for each source you want in the mix.
Trim Each Clip to the Exact Start and End Time
Every clip gets its own waveform. Drag the in/out handles, or type exact timestamps into the In and Out fields, to select precisely the section you want. The rest of the source video is never included in the export.
Reorder Clips, Add Fades and Insert Gaps
Drag clips by their grip handle to change the order they play in. Each clip has its own fade-in and fade-out length and volume level, so you can smooth transitions between sources or balance louder and quieter clips against each other.
Combine Multiple Clips into One MP3
Once your clips are trimmed, ordered and balanced, hit Export MP3. TubeMixLab downloads the audio for each source, cuts the exact sections you chose, and stitches them into a single MP3 — 320kbps or 128kbps, your choice — you can preview and download.
Why Use TubeMixLab?
Most YouTube-to-MP3 tools only handle one video at a time. TubeMixLab is built specifically for combining multiple clips — with per-clip trimming, reordering, fades and volume control — in the browser, with no account and no software to install.
Frequently Asked Questions
Is TubeMixLab safe?
Yes. Nothing to install, no ads, no popups, no account. Processing happens on our servers, not in a downloaded program, and every exported file is deleted after 30 minutes. TubeMixLab is run by an independent developer — see the About page for how it works.
Can I combine multiple YouTube clips into one MP3?
Yes — that's the core of the mixer. Add each clip's URL, trim it, arrange the order, then export a single MP3 that plays all of them back to back. For joining whole songs from several videos, the YouTube audio merger is set up for exactly that.
Can I choose a different start and end time for every clip?
Yes. Each clip has its own independent waveform and In/Out handles, so you can select a different section from every source video in the mix.
Can I reorder clips before exporting?
Yes, drag any clip by its grip handle to move it earlier or later in the final mix. The preview timeline below updates as you reorder.
Can I add a fade-out between clips?
Yes. Every clip has its own fade-in and fade-out length in seconds, so transitions between clips can be smoothed instead of cutting abruptly.
Can I add silence between two clips?
Clips play back to back by default. For a gap, trim a short silent moment from a source clip and place it between the two clips you want separated.
What's the difference between the mixer and the YouTube-to-MP3 converter?
The YouTube to MP3 Converter turns one full video into one MP3. The mixer on this page is for combining and trimming multiple clips into a single track.
Can I convert only part of a YouTube video to MP3?
Yes — add a single clip here, trim it to the section you want, and export. For a page built specifically around that single-clip workflow, see the YouTube Audio Cutter.
Do I need an account to use TubeMixLab?
No. There's no signup, no install and no watermark — paste a link and start trimming.
