WAV to OGG
Free online compression of WAV lossless audio to OGG (Opus) format, reducing file size by up to 90% while maintaining excellent quality. Supports WAV, MP3, and FLAC input. Processed entirely in your browser — files are never uploaded to any server.
Privacy Protection
All conversion happens locally in your browser. WAV files are never uploaded to any server, keeping your audio private.
Tiny File Size
WAV to OGG can reduce file size by 90% — a 10 MB WAV compresses to approximately 1 MB OGG, saving storage and bandwidth
Excellent Audio Quality
OGG Opus is the most efficient audio codec available — at 128 kbps it delivers near-lossless listening quality, surpassing MP3 at the same bitrate

3 Steps to Convert WAV to OGG
Upload your WAV file
Click the upload area or drag and drop WAV, MP3, or FLAC audio files. Supports files up to 2 GB.
Select Quality
Choose the OGG output bitrate for your use case. 128 kbps suits most scenarios.
Convert and download
Click Convert, then download the OGG file once processing is complete. Everything runs in your browser — no account required.
Typical Use Cases for WAV to OGG
Game Sound Effect Compression
Game sound effects are typically recorded in WAV format, resulting in very large files. Converting WAV sound effects to OGG in bulk can significantly reduce game package size, while OGG is natively supported in major engines like Unity and Godot with lower latency.
Website Audio Optimization
Website background music and notification sounds served as WAV files load slowly and degrade the experience. Converting to OGG reduces the file size by 90%, improving page load speed, with native playback in Chrome and Firefox — no extra plugins needed.
Android App Development
Android natively supports OGG (Opus/Vorbis) with no decoders required. When developing Android apps, converting WAV recordings or sound effects to OGG results in a smaller APK, faster audio loading, and a better user experience.
Podcast and Recording Distribution
WAV files recorded in a studio can easily reach several hundred MB. Converting to OGG compresses them to tens of MB, significantly reducing hosting costs and listener bandwidth usage. Linux users can play them directly in the system player without installing additional software.
Differences Between WAV and OGG
| Comparison | WAV (lossless uncompressed) | OGG Opus (Lossy Compression) |
|---|---|---|
| File Size | Large — about 10 MB/min (44.1 kHz stereo) | Small — approximately 1 MB/min at 128 kbps, 90% smaller |
| Audio quality | Lossless — fully preserves the original audio data | Lossy — at 128 kbps, the difference is barely perceptible to the human ear |
| Browser Support | Supported in all browsers | Supported in Chrome, Firefox, and Edge; not supported in Safari |
| Game Engines | Supported in all game engines, but with large file sizes | Supported in Unity and Godot; the recommended format for Godot |
| Use Cases | Professional production, audio archiving, and workflows requiring lossless quality | Web audio, game sound effects, Android apps, and Linux systems |
Supported input formats
- WAV — lossless uncompressed format, commonly used in recordings and professional production; largest file size
- MP3 — lossy compression format; converting to OGG yields a better compression ratio
- FLAC — lossless compressed format; converting to OGG can reduce file size by over 70%
Technical Notes
The VideoKit WAV to OGG tool is based on the WebCodecs API. It decodes WAV/MP3/FLAC audio streams directly in the browser and encodes the result with the Opus encoder, packaged in the OGG container format. Opus is a modern IETF-standard codec supported natively by browsers — no WASM plugin required.
The entire process runs locally. No audio data is sent to any server. The output OGG files are compatible with Chrome, Firefox, Edge, Android, Linux, and game engines including Unity and Godot.
Frequently Asked Questions
Why Convert WAV to OGG?
WAV files are very large and unsuitable for network delivery and mobile storage. OGG offers up to 90% compression while maintaining excellent audio quality, making it ideal for web audio, game sound effects, and Android apps.
Will converting WAV to OGG result in quality loss?
There will be minor quality loss, but Opus encoding at 128 kbps delivers excellent audio quality — in everyday music listening, most people cannot distinguish it from WAV.
How much smaller will the file be after conversion?
A 10 MB WAV file converts to approximately 1 MB OGG at 128 kbps — about 90% smaller. Choosing 96 kbps reduces the size further; 64 kbps is suitable for voice content.
Will my files be uploaded to a server?
No. All processing is done locally in your browser — your WAV file never leaves your device, fully protecting your privacy.
Which platforms support OGG?
Natively supported on Linux and Android. Native playback in Chrome, Firefox, and Edge. Supported in Unity and Godot game engines. iOS/macOS do not natively support OGG.
Which bitrate should I choose?
128 kbps is recommended for music, 96 kbps works well for game sound effects, and 64 kbps is sufficient for voice content. Opus encoding is highly efficient — audio quality is excellent at all of these bitrates.
What is the maximum WAV file size?
WAV files up to 2 GB are supported. WAV files can be very large, so it is recommended to process large files on a device with sufficient memory.
Which Input Formats Are Supported?
WAV, MP3, and FLAC are all supported as input and can each be converted to OGG in one click.
