YouTube to MP3 — Preview Any Link, Convert Your Own Files Locally

Link preview via oEmbed; your own video→MP3 conversion runs on-device with a WebAssembly FFmpeg engine.

Quick answer: Paste a YouTube link for instant title/thumbnail preview, or convert your own video files to MP3 right in the browser. No uploads, no watermark.

⚖️ Only fetch or convert content you own or have permission to use. Respect copyright and each platform's Terms of Service.

YouTube URL (preview)

Or your own video file

⚡ Advanced — real file downloads via your own server (optional)

A browser alone cannot save video files from most platforms. If you run your own cobalt server (free & open-source), connect it below once — it is stored only in YOUR browser, and file downloads then run entirely through YOUR server, never through ours. Set a primary (e.g. an always-on Oracle Cloud free VPS) and optionally a Render/Koyeb backup — if the primary is asleep or offline, downloads switch to the backup automatically. Only save content you own or have the right to keep.

Free always-on server (Oracle Cloud, no sleep) + free Render backup in ~10 minutes, exact settings: full step-by-step guide →

How to use

Paste a YouTube URL → preview card appears.
Or drop your own video file → press Extract MP3.
The MP3 downloads straight from your device.

About this tool

This tool does two honest jobs. First, paste any YouTube URL and it pulls the official oEmbed metadata (title, author, thumbnail) instantly so you can catalogue or verify a link. Second — and this is the part that never touches anyone's server — drop your own video file and the in-browser FFmpeg engine extracts the audio track to a clean 192k MP3. Ripping streams from YouTube violates its Terms of Service and copyright law in most cases, so we don't pretend otherwise: the disclaimer stays visible and the conversion engine works on files you already own. Your file never leaves this page — processing runs in your browser via WebAssembly; nothing is uploaded and the file is dropped from memory when you close the tab.

FAQ

Does it download audio from YouTube?

No — stream ripping breaks YouTube's ToS and copyright. You get link preview plus local conversion of files you own.

Is my file uploaded?

No — Your file never leaves this page — processing runs in your browser via WebAssembly; nothing is uploaded and the file is dropped from memory when you close the tab.

What quality is the MP3?

192 kbps CBR, 44.1/48 kHz preserved from source.

Which formats can I feed it?

Any container your browser's FFmpeg build decodes: mp4, mov, webm, mkv mostly.

Why the disclaimer?

Because a tool that silently rips copyrighted streams would be helping you lose, not win.
