Embed Our Converter on Your Website
Add a free, privacy-first video-to-MP3 converter to any site with one line of HTML
Live Preview
This is exactly what it looks like embedded on a page. Go ahead — drop a video file and try it right here.
Quick Start — One Line of HTML
Copy this code, paste it anywhere on your page, and you're done:
<iframe
src="https://getmp3.video/embed-widget.html"
width="480" height="520"
frameborder="0"
style="border:none; border-radius:12px"
title="Video to MP3 Converter"
></iframe>That's literally it. No JavaScript SDK, no npm package, no build step. Works on static HTML, WordPress, React, Vue, Shopify — anything that renders HTML.
How It Works Under the Hood
Understanding the technology helps you explain it to your users:
Widget Loads FFmpeg.wasm
When the iframe loads, it downloads a WebAssembly build of FFmpeg (the same engine used by YouTube, VLC, and professional studios). This runs entirely inside the browser — no server involved.
User Drops a Video File
The video file stays in the browser's memory. It is never uploaded to any server. Even on a slow internet connection, processing is fast because it's local.
FFmpeg Extracts the Audio Track
The audio track is extracted and re-encoded to MP3 at the user's chosen bitrate (128, 192, or 320kbps). A typical 4-minute video converts in 5-15 seconds.
User Downloads the MP3
The MP3 is generated as a Blob URL and downloaded directly. When the tab closes, all data is cleared from memory. Zero trace left.

Customization Examples
Responsive Width
Set width="100%" and wrap in a max-width container for responsive behavior:
<div style="max-width:480px; margin:0 auto">
<iframe
src="https://getmp3.video/embed-widget.html"
width="100%" height="520"
frameborder="0"
style="border:none; border-radius:12px"
></iframe>
</div>Shadow & Rounded Corners
Match your design system with custom shadows and border radius:
<iframe
src="https://getmp3.video/embed-widget.html"
width="480" height="520"
style="border:none;
border-radius:16px;
box-shadow:0 8px 32px rgba(0,0,0,0.15)"
></iframe>WordPress
Add a Custom HTML block in the Gutenberg editor, paste the iframe code. No plugin needed.
<!-- Paste in Custom HTML block -->
<div style="text-align:center">
<iframe src="https://getmp3.video/embed-widget.html"
width="100%" height="520" frameborder="0"
style="border:none; max-width:480px;
border-radius:12px"></iframe>
</div>React / Next.js
Use a standard iframe. CSP headers may need frame-src getmp3.video.
function Mp3Converter() {
return (
<iframe
src="https://getmp3.video/embed-widget.html"
width="480" height="520"
frameBorder="0"
style={{border:'none', borderRadius:'12px'}}
title="Video to MP3 Converter"
/>
);

Frequently Asked Questions
Yes, 100% free. No limits, no payment, no signup required. The only requirement is keeping the "Powered by GetMP3.video" branding in the widget. There is no freemium tier — all features are included.
No. It's a self-contained iframe. Paste one line of HTML and it works immediately. No SDK, no npm install, no build step, no account creation.
No. The widget has zero analytics, zero tracking cookies, and zero data collection. All file processing happens in the visitor's browser memory and is erased when the tab closes. This makes it GDPR and CCPA compliant by default.
