WhatsApp voice notes are saved as Opus audio in .opus or .ogg files, and plenty of laptops, car stereos, editing apps and older phones refuse to open them. This free converter turns them into MP3s that play almost anywhere. Choose one voice note or a whole batch, and they’re converted right on your phone: nothing is uploaded.
How it works
- On WhatsApp, open the chat, long-press the voice note and share or export it to your phone's files (see the tips below).
- Choose one or more voice notes (.opus, .ogg, .m4a, .aac) or videos here. They are converted on your device.
- Optionally make quiet voice notes louder and even.
- Download each file as an MP3 that plays on almost anything: laptops, car stereos, editing apps and older phones.
Frequently asked questions
How do I get a voice note out of WhatsApp?
On Android, long-press the voice note, tap the share icon and save it to your files, or find it in your file manager under Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Voice Notes. On iPhone, long-press the voice note, tap Forward, then the share icon, and choose Save to Files. Then choose that file here.
Why convert a voice note to MP3?
WhatsApp saves voice notes as Opus audio in .opus or .ogg files. Many laptops, car stereos, older phones, editing apps and office systems can't open them. MP3 plays almost everywhere and is easy to attach, edit or keep as evidence of what was said.
Is it private?
Yes. Voice notes are personal, so the conversion happens entirely in your browser. The file is never uploaded to Centertainment or anyone else. Please only convert voice notes you are entitled to keep and share, and respect the privacy of the people in them.
Which MP3 quality should I choose for voice notes?
Voice notes are recorded at low bitrates, so 64 kbps (our default for this tool) keeps all the detail and makes small files. Choose 128 kbps or higher for music or videos.
Which file types work?
Anything your browser can play: MP3, WAV, M4A and AAC work almost everywhere, and FLAC, OGG and OPUS work in most browsers (for Opus voice notes we include a fallback decoder). You can also choose an MP4, MOV or WebM video and the tool uses its soundtrack. Old AMR voice recordings are not supported by browsers.
Is Audio Lab free?
Yes. Every tool on this page is free, with no sign-up, no watermark and no daily limit. Free files can be up to 10 minutes long (8 minutes for the vocal remover). A Pro version with high-quality cloud stem splitting, batch processing and longer files is planned; you can join the waitlist, and nobody is charged anything today.
Terms of use and copyright
- Only process audio you own or have permission to use: your own recordings, beats you have licensed, or tracks whose licence allows editing. Removing vocals, cutting or converting a song does not give you any rights to it.
- Don't publish, sell, stream or perform results made from other people's music without permission from the rights holders. Platforms may mute, block or claim such uploads, and you are responsible for how you use what you make.
- Audio Lab does not download or fetch audio from links (YouTube, TikTok, Instagram, Spotify, Audiomack, Boomplay or anywhere else) and does not host any music. You choose files that are already on your device.
- Your files are processed in your browser and never uploaded to Centertainment. We don't see, store or keep copies of your audio. Voice notes may contain other people's voices: respect their privacy.
- The tools are provided free and "as is". Results are automatic and can contain artefacts, so check them before you share, and keep your original files.
Get the voice note out of WhatsApp
- Android: long-press the voice note in the chat, tap the share icon and save it to your files. You can also find recent voice notes in your file manager under Android, media, com.whatsapp, WhatsApp, Media, WhatsApp Voice Notes (organised in weekly folders).
- iPhone: long-press the voice note, tap Forward, then the share icon at the bottom right, and choose Save to Files.
- WhatsApp Web or Desktop: open the menu on the voice note and choose Download.
Convert and keep
Choose the files here and press Convert to MP3. Each one gets its own download button. We default to 64 kbps, which keeps all the detail a voice note has while making small files; pick a higher setting if you are converting music or video soundtracks. Quiet recording? Tick “Make quiet recordings louder” to bring it up to a clear, even level without distortion.
Common reasons people convert voice notes
To keep a recording of a loved one’s voice safely backed up; to send audio to someone who doesn’t use WhatsApp; to transcribe a long message (try our Caption & Transcript Studio next); to keep a record of instructions from a client or landlord; or to edit a voice note into a podcast or video. Hiss in the background? Clean it with the noise cleaner on the Audio Lab page.
Privacy first
Voice notes are personal, which is exactly why nothing leaves your device. Please only convert and share voice notes you are entitled to, and respect the privacy of the people speaking in them.
