Can I convert a WhatsApp voice note to MP3?

Yes. WhatsApp voice messages are Opus audio in an .ogg or .opus file, and this tool decodes both. Save the note to your device, drop it here and you get an MP3 that opens in any email client, messaging app or media player.

What is the difference between OGG, OGA and OPUS files?

Ogg is a container, not a codec. A .ogg or .oga file usually holds Vorbis audio, while .opus holds Opus audio in the same container. Tinyvert reads all three and detects the codec automatically.

Will the MP3 sound as good as the original?

At 192 kbps or above the difference is inaudible to almost everyone. Both formats are lossy, so re-encoding does lose a little, but at a sensible bitrate it is not something you will hear.

Which bitrate should I choose for voice recordings?

64 or 96 kbps is plenty for speech and keeps the file small. Use 192 kbps or higher for music.

Are the title and artist tags kept?

Yes. Vorbis comments (title, artist, album, cover art) are copied into ID3 tags in the MP3 where present. Voice notes rarely carry any tags, so there is simply nothing to copy.

Is the file uploaded anywhere?

No. Decoding and MP3 encoding both run inside your browser, so a private voice message stays on your device.

What is actually inside an OGG file

Ogg is a container rather than a codec, and that explains most of the confusion around it. A .ogg downloaded in 2008 almost certainly holds Vorbis audio; a .ogg saved from WhatsApp today holds Opus. Telegram, Signal and Discord voice messages are Opus too. Tinyvert does not care which: the browser's own Vorbis and Opus decoders read the stream, and the result is written out as MP3 by the LAME encoder, compiled to WebAssembly and fetched on first use (about 300 KB).

Where these files come from

Voice notes exported from WhatsApp, Telegram or Signal: a few hundred kilobytes of Opus at a very low bitrate.
Game assets. Minecraft, Unity and Godot projects and countless indie titles ship music and effects as Ogg Vorbis.
Wikipedia and Wikimedia Commons, which publish pronunciations and recordings only in patent-free formats.
Linux desktops and older rippers that defaulted to Vorbis before the last MP3 patents expired in 2017.

Every one of those plays happily in VLC or a browser. The trouble starts when the destination is a car stereo, an old iPod, a transcription service, a podcast host or a colleague who taps the file on their phone and sees nothing happen. MP3 is the one format all of them understand.

Picking a bitrate

Source	Suggested MP3 bitrate	Why
Voice note (Opus, 16–32 kbps)	64–96 kbps	Speech needs little; more only inflates the file
Podcast or audiobook	96–128 kbps	Clear speech at a modest size
Vorbis music at quality 5–6	192 kbps	Matches the source
High-bitrate Vorbis or Opus music	256–320 kbps	Keeps the re-encode transparent

One thing to expect: a voice note will usually get bigger. Opus is remarkably efficient at 24 kbps and MP3 cannot match it, so the row may show a size increase rather than a saving. That is normal, and it is the price of universal playback.

What stays the same

Sample rate and channel count are preserved, so a stereo 44.1 kHz Vorbis track becomes a stereo 44.1 kHz MP3. Opus always decodes at 48 kHz, which MP3 supports natively. Vorbis comments are written into the MP3's ID3 tags, so a converted album still sorts correctly in your music library. Batches run one file after another with a progress bar on each row, and the ZIP behind "Download all" is assembled locally.

Going the other way, or somewhere else

Need the opposite? MP3 to OGG writes modern Opus. For a lossless target use the Audio Converter and choose WAV or FLAC. If the goal is simply a smaller file, Compress Audio defaults to a lean 96 kbps MP3.

How to convert ogg to mp3 — step by step

Drop up to five OGG, OGA or OPUS files into the box, or click "Choose files".
Pick a bitrate from the menu. 192 kbps is the default; 64 or 96 kbps suits voice notes.
Press Convert and watch the progress bar on each row; the size change appears when a file is done.
Download each MP3 or grab them all as a ZIP. On a phone, use Share to send the result straight to another app.
