About Audio Converter
We believe audio conversion should be free, fast, and private. No uploads, no accounts, no compromises.
Our Mission
Audio Converter was created with a simple goal: provide the best free online audio conversion tool that respects your privacy. We noticed that most online converters require you to upload your files to their servers, which raises privacy concerns and takes longer.
Our solution uses WebAssembly technology to run FFmpeg directly in your browser. This means your audio files never leave your device - all processing happens locally on your computer.
Our Values
Privacy First
Your files stay on your device. We don't upload, store, or have access to any of your audio files.
Speed Matters
Local processing means no upload/download time. Conversions happen at near-native speed.
Free for Everyone
No registration, no limits, no premium tiers. Full functionality for all users.
Open & Transparent
Built with open-source technology. We're transparent about how our tool works.
Our Technology
Audio Converter is powered by FFmpeg compiled to WebAssembly. FFmpeg is the industry-standard multimedia framework used by professionals worldwide. By running it in your browser, we bring professional-grade conversion capabilities to everyone.
We support 18 audio formats including MP3, WAV, FLAC, OGG, M4A, AAC, OPUS, and more. Whether you need lossy compression for smaller files or lossless quality for archival, we've got you covered.
