Tool guide
The OGG container carries most of the free-codec world: messenger voice notes with Opus inside, sounds from open-source game engines, old Vorbis dumps. Plenty of desktop editors refuse to open them, while every editor takes a plain WAV. This page decodes the OGG with the browser's own engine and writes PCM at the original rate, keeping the data inside the tab; the WAV to OGG tool compresses it back.
Save the audio out of the chat — in Telegram that is Save As on the message — and it usually arrives as .ogg or .oga. Rename it to .ogg if needed, select it here and press convert. The resulting WAV opens in any editor and suits speech-transcription software.
Both, as long as your browser can decode them, and current Chrome and Firefox handle Vorbis and Opus alike. Voice notes are almost always Opus; older game sounds are Vorbis. There is no codec switch — it is detected from the file itself.
Opus is defined at 48 kHz and always decodes to it, even when the microphone captured 16 or 24 kHz. Nothing is degraded; the signal is simply represented with more samples. Resample afterwards in an editor if your pipeline needs a specific rate.
The field accepts .ogg and audio/ogg, so the system dialog hides other extensions. Rename a copy to .ogg — the container contents are unchanged and the browser identifies the codec from the data. The same applies to .oga.
Opus at speech bitrates is extremely efficient, fitting a minute of voice into a few tens of kilobytes. WAV stores every sample in full, so the same minute of 48 kHz mono is about 5.5 MB. A 50-100x jump is normal for voice notes.
No. The file stays in tab memory: the page reads it locally, decodes it with the browser and builds the WAV on your device. No network request carries audio, so private voice notes never reach a third-party service.
