Is this WhatsApp audio to MP3 converter free?

Yes. It’s free, with no account and no limit on the number of voice notes.

Are my voice notes uploaded anywhere?

No. The conversion runs in your browser on your own device, so the voice notes and the MP3s stay with you.

Why is my WhatsApp audio file an .opus file?

WhatsApp records voice notes with the Opus codec, which keeps speech clear in very small files. Many players don’t open it, which is why converting to MP3 helps.

Can I convert several voice notes at once?

Yes. Add all the files together, from a folder or an exported chat, and each one becomes its own MP3 with its original name.

How do I get a voice note off my iPhone?

Touch and hold the voice note, tap Forward, then the share button, and choose Save to Files. Then add the file to this page in Safari.

Where are WhatsApp voice notes stored on Android?

In Internal storage, Android, media, com.whatsapp, WhatsApp, Media, WhatsApp Voice Notes, in folders by year and week. Older phones use Internal storage, WhatsApp, Media, WhatsApp Voice Notes.

Will the MP3 sound worse than the voice note?

No. At 128 kbps the MP3 holds everything the voice note carries, so the words sound the same; it can’t sound better than the original either.

Can I turn WhatsApp audio into text?

Yes. After converting, send the MP3 to the transcriber, which writes out what was said.

The same on a phone or a computer.

Save the voice note
Share it out of the chat, or copy it from the WhatsApp Voice Notes folder. You get a small .opus file.
Add it here

Download the MP3
Play it, then save it. Send it on to the transcriber if you would rather read the message than hear it.

Why convert WhatsApp audio here

Made for the voice notes people actually keep.

Step by step for Android and iPhone

Getting the file out of WhatsApp is the hard part, so this page shows where Android keeps voice notes and how an iPhone saves one to Files. Once you have the .opus file, the rest takes seconds.

Opus in, MP3 out

WhatsApp saves voice notes as Opus, a format many players, car stereos and editing tools don’t open. The converter reads the Opus sound and writes a standard MP3 that every device plays.

On the phone that has the notes

Open this page on the phone itself: the browser converts the note right there, with no app to install, and the MP3 goes to your downloads or Files, ready to send.

A whole chat at once

Export a chat with its media, or select a week’s notes from the folder, and drop them all in. Each MP3 keeps the note’s own file name, so the order stays clear.

The right size for speech

A voice note is mono speech, so the converter keeps it mono and suggests 128 kbps: clear words in a small MP3. A minute comes out at under 1 MB.

From a voice note to text

A long message from a client or a relative can go straight to the transcriber, which writes out every word, without downloading it and choosing it again.

WhatsApp audio to MP3 samples

Voice notes made the way WhatsApp saves them, mono Opus speech at about 24 kbps, from this site’s own recordings, then converted here. Compare the spectrum and the size of each note and its MP3.

Personal messages stay personal
Voice notes from friends and family stay on your device from start to finish.
No sign-up
Convert one note or a whole chat without an account or an email address.
Names kept
Each MP3 keeps the note’s file name with its date, ready to sort and archive.

WhatsApp audio guide: saving voice notes and converting them

What format WhatsApp audio is

WhatsApp records voice notes with the Opus codec inside an Ogg file and gives the file the .opus ending. Opus keeps speech clear at a very low bitrate, so a minute of talking is often less than 200 KB.

The catch is support. Phones play these files inside WhatsApp, but many music apps, car stereos, media players on Windows and video editors don’t open .opus. MP3 opens everywhere, which is why people convert WhatsApp audio to MP3 before keeping or sharing it.

Saving a voice note on Android

Android keeps every voice note you send and receive as a file, so you can share one or copy many.

1In the chat, touch and hold the voice note, then tap the share button and send it to your email, cloud storage or Nearby Share.
2Or open the Files app and go to Internal storage, Android, media, com.whatsapp, WhatsApp, Media, WhatsApp Voice Notes. The notes sit in folders named by year and week.
3On older Android versions the folder is Internal storage, WhatsApp, Media, WhatsApp Voice Notes.

Saving a voice note on iPhone

An iPhone keeps voice notes inside WhatsApp, so save each one you want to keep.

1Open the chat and touch and hold the voice note.
2Tap Forward, then tap the share button in the corner.
3Choose Save to Files and pick a folder. Open this page in Safari and add the file from the same folder.

Voice notes sent as View once can’t be saved or forwarded; that is how WhatsApp designed them.

Saving a whole chat’s voice notes

To keep every voice note in a conversation, export the chat with its media. On Android, open the chat, tap the three dots, then More and Export chat, and choose Include media. On iPhone, open the contact or group info, tap Export Chat and choose Attach Media.

The export holds the voice notes as .opus files next to a text file of the messages. Add all the .opus files here at once; each one becomes its own MP3.

Does converting change the sound?

Converting can’t add detail that the voice note never had, and it doesn’t need to. An MP3 at 128 kbps holds far more than a mono voice note at about 24 kbps carries, so the words sound exactly as they did in the chat. Higher bitrates only make the file bigger.

If you plan to edit the audio, for example to cut a note into a video, convert to WAV instead and make the MP3 at the end.

Other Opus files

Telegram, Signal and many recorders also save Opus, sometimes as .ogg or .oga. They convert the same way: this page is an Opus to MP3 converter as much as a WhatsApp one. For other formats, use the MP3 converter, which reads every file the browser can decode.

Very old WhatsApp voice messages may be .amr files, which browsers can’t decode. The converter tells you when a file is one of these.
