About OGG Audio
OGG (Ogg Vorbis) is an open, patent-free audio format that offers quality comparable to or better than MP3 at equivalent bitrates. Developed by the Xiph.Org Foundation, it's natively supported in Firefox, Chrome, and Android. Vorbis excels at mid-range bitrates (96-192kbps) where it consistently outperforms MP3 in listening tests.

Why privacy matters for file conversion
Most online converters upload your files to remote servers where they may be scanned, stored, or shared. This tool is different — the conversion runs in your browser via WebAssembly or the WebCodecs API. Your files stay on your device. Always.

Frequently asked questions
OGG Vorbis produces better audio quality than MP3 at the same bitrate, especially below 192kbps. However, MP3 is supported everywhere. Use OGG for open-source projects and gaming; MP3 for maximum compatibility.
Yes, completely free with no file limits. The conversion engine runs directly in your browser — we have zero server costs for processing, so we can offer it at no charge.
Your file never leaves your device. The conversion engine runs 100% in your browser using WebAssembly or the WebCodecs API. We have no access to your files — no uploads, no logs, no data collection whatsoever.
On desktop browsers (Chrome, Firefox, Edge) files up to 500 MB convert reliably. On Safari (macOS) the practical limit is around 200 MB. On iPhone and iPad, keep files under 50 MB — iOS enforces tight memory limits for browser-based processing.
On your first visit, the browser downloads the conversion engine (24–50 MB depending on which backend is used). This is cached locally, so subsequent conversions load much faster.
Chrome, Edge, and Brave use hardware-accelerated WebCodecs when the format is supported — this is 5–10× faster than software encoding. For unsupported formats the tool falls back to ffmpeg.wasm, where Firefox typically performs best.
