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.
