Turn a WAV file into a compact OGG/Opus file using your browser's native encoder.
The WAV to OGG converter turns WAV audio (Waveform Audio File Format (RIFF, usually uncompressed PCM)) into OGG (Ogg container, usually with Vorbis or Opus audio) directly in your browser. OGG/Opus delivers much smaller files than WAV with very good quality and no licensing restrictions.
WAV is the editing and archiving standard — uncompressed, sample-accurate and supported by every audio application. OGG is a fully open, patent-free format used in games, Linux and web audio. Going from WAV to OGG discards some audio information to save space. Choose a high bitrate (192–320 kbps for music, 96–128 kbps for speech) to keep the result close to the original.
Your file is decoded to 32-bit floating-point samples by the browser’s own audio decoder — and at the file’s own sample rate, not a resampled one. You can optionally resample or switch channels. It is then encoded to OGG on your device; for a lossy target the result is decoded again for the preview, so you hear what you will get. Typical size: about 0.7–1 MB per minute at ~128 kbps.
Source format facts: WAV files are lossless; usual bandwidth: full bandwidth up to the Nyquist limit. Target facts: OGG is lossy; usual bandwidth: quality-based; up to 20 kHz+.

Opus is more efficient than MP3 at the same bitrate.
Most modern players and browsers do; some car stereos do not.
Going to WAV is lossless. Going to MP3 uses a standard 192kbps encode by default (adjustable), which is transparent for most listening but is a lossy step if your source was uncompressed.
No — the file is decoded and re-encoded entirely in your browser using the Web Audio API and, for MP3, a small bundled encoder. Nothing is sent anywhere.
This tool runs entirely in your browser using the Web Audio API. Nothing is uploaded, stored or shared — there is no server to send your file to, so it works offline once the page has loaded.
