About Us - To MP3 Converter

Our Mission

To MP3 Converter was built to give everyone a simple, trustworthy way to convert audio and video files to MP3. Whether you need to extract music from a video, shrink a large WAV file, or make an obscure format playable on your phone, our tool handles it in seconds — with no software to install and no account required.

Unlike most online converters, we never upload your files to a server. Every conversion runs locally on your device using WebAssembly and FFmpeg, so your content stays private from start to finish.

What We Stand For

Privacy First

Your files never leave your device. We have no access to what you convert, and we do not store any media on our servers.

Modern Technology

We use FFmpeg compiled to WebAssembly for near-native conversion speed directly in the browser — no plugins or desktop apps needed.

Universal Access

Our tool works on desktop and mobile browsers, supports 30+ input formats, and is available in multiple languages.

Free for Everyone

No subscriptions, no daily limits, and no watermarks. We believe essential media tools should be accessible to all.

How It Works

When you select a file, our converter loads a compact FFmpeg engine into your browser tab. The engine decodes your input file, encodes it as MP3 using the LAME codec, and triggers a download — all without sending data over the network.

This client-side approach means conversion speed depends on your device, but it also means your files are never exposed to third-party servers. It is the same technology trusted by developers worldwide, adapted for everyday users.
