Is my audio file uploaded to a server?

No. The Web Audio API and MediaRecorder run entirely inside your browser. Your file is loaded into browser memory only and is never transmitted to any server.

Why does the output say WebM instead of OGG?

MediaRecorder support varies by browser. Chrome and Edge support OGG natively and produce an .ogg file. Firefox and Safari record to WebM, which is also an open format and plays in all modern browsers. The audio content is identical — only the container differs.

Will the audio quality be the same as the original WAV?

WAV is lossless, so the OGG output will be a lossy re-encoding. At the default quality setting (~128 kbps variable bitrate), the result is transparent for most listeners. Some high-frequency detail may be slightly reduced compared to the original.

What WAV file types are supported?

Standard PCM WAV files (8-bit, 16-bit, 24-bit, 32-bit float) are supported by the Web Audio API in all modern browsers. RF64 and compressed WAV variants may not decode correctly.

What browsers are supported?

Chrome 47+, Edge 79+, Firefox 25+, and Safari 14.1+. The tool detects MediaRecorder support and shows a warning if your browser cannot encode audio. OGG output is available in Chrome and Edge; WebM output in Firefox and Safari.

How large a WAV file can I convert?

This depends on your device memory. Files up to 100 MB work reliably in most browsers. Very large files (500 MB+) may exceed available memory and cause the browser tab to crash. For very large files, a desktop tool like Audacity or FFmpeg is recommended.

Summary

OGG Vorbis is an open, royalty-free audio codec widely used in web games, Linux desktops, and open-source software. This tool converts your WAV in the browser using the Web Audio API and MediaRecorder — your file is never sent to a server. The actual output is OGG when the browser exposes an OGG recorder, otherwise WebM. MediaRecorder runs against the live audio clock, so conversion takes approximately the source duration.

How it works

Click the upload area or drag a WAV file onto it.
The Web Audio API decodes the WAV into raw PCM audio data.
MediaRecorder re-encodes the audio to OGG Vorbis (or WebM on some browsers).
A download button appears once encoding is complete.
Click "Download" to save the converted file to your device.
Your audio never leaves your browser at any point.

Use cases

Prepare audio assets for HTML5 web games that require OGG format.
Convert WAV recordings to a smaller, compressed format for the web.
Create OGG files for use in game engines such as Godot or Pygame.
Reduce WAV file size while keeping reasonable audio quality.
Provide OGG fallback audio alongside MP3 for browser compatibility.
Archive uncompressed WAV files in an open, patent-free audio format.
Convert voice recordings or sound effects for web embedding.
Produce OGG files for open-content platforms like Wikipedia.
