Convert WhatsApp & Telegram
Voice Messages to MP3

Why Voice Messages Are Opus Files

WhatsApp adopted the Opus codec in 2016 for all voice messages and voice notes. Telegram uses the same codec, wrapping Opus audio inside an OGG container. Both apps chose Opus for the same reason: it delivers excellent speech clarity at remarkably low bitrates — typically just 16–32 kbps.

At these bitrates, a one-minute voice message is only about 100–200 KB. That is roughly 10× smaller than the same recording in MP3. For messaging apps serving billions of users on mobile networks, this efficiency is critical — it reduces bandwidth costs, speeds up delivery, and saves storage on users' phones.

The downside is compatibility. While Opus plays perfectly inside WhatsApp and Telegram, trying to play an .opus or .ogg file outside the app often fails. Most car stereos, basic media players, and older devices simply do not recognize Opus. Converting to MP3 solves this instantly.

How to Find Voice Messages on Android

WhatsApp (Android)

WhatsApp stores voice messages in a specific folder on your device. The exact path depends on your Android version:

• Android 10 and earlier: Open any file manager and navigate to Internal Storage/WhatsApp/Media/WhatsApp Voice Notes/. Voice messages are organized into date-based subfolders (e.g., 202603/).
• Android 11+: WhatsApp moved to scoped storage. The new path is Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Voice Notes/. You may need a file manager like Files by Google or Solid Explorer to access this directory.

Each voice message is an .opus file named with a timestamp. Individual voice notes sent to you are in the WhatsApp Voice Notes folder, while audio messages recorded in chats may also appear in WhatsApp Audio.

Telegram (Android)

Telegram voice messages are stored in Internal Storage/Telegram/Telegram Audio/. Alternatively, you can long-press a voice message in any chat and tap Save to Downloads to copy it to your Downloads folder as an .ogg file.

How to Find Voice Messages on iPhone

WhatsApp (iPhone)

iOS does not allow direct file system access to WhatsApp's storage. Instead, use one of these methods:

• Forward to Files: Long-press the voice message in the chat → tap Forward → tap the Share icon → select Save to Files. The .ogg file is now in your Files app.
• Email to yourself: Long-press → Forward → Share → Mail. Send it to your own email, then download the attachment on any device.
• Share to Convertio: Long-press → Forward → Share → open in Safari and go to convertio.com. Upload the file directly.

Telegram (iPhone)

In Telegram, tap the voice message to open it, then tap the Share button (or the three-dot menu) → Save to Files. The file saves as an .ogg file in your chosen location.

Method 1: Convert Online (Works on Phone)

The fastest approach — works directly in your mobile browser with no app installation:

1. Save the voice message to your phone using the methods described above.
2. Open Convertio.com in Safari (iPhone) or Chrome (Android).
3. Tap "Choose File" and select the .opus or .ogg file from your Downloads or Files app.
4. Tap "Convert to MP3" and wait a few seconds — voice messages are tiny and convert almost instantly.
5. Tap "Download MP3" to save the converted file.

The entire process takes under 30 seconds. The resulting MP3 file plays on every device, every media player, and every car stereo.

Method 2: Desktop Tools

If you prefer to convert files on your computer:

• VLC Media Player (free, cross-platform): Open VLC → Media → Convert/Save → Add your .ogg file → Select MP3 as output format → Start.
• Audacity (free, open-source): File → Import → Audio → Select the Opus file → File → Export → Export as MP3. Audacity also lets you trim, amplify, or edit the audio before exporting.
• FFmpeg (command line): ffmpeg -i voice.ogg -c:a libmp3lame -b:a 128k voice.mp3. The fastest method for batch converting many files at once.

Recommended MP3 Settings for Voice Messages

Voice messages are recorded at very low bitrates (16–32 kbps Opus), so converting to a high-bitrate MP3 offers no quality improvement — it only makes the file bigger. Here are sensible settings:

128 kbps is the sweet spot: it fully preserves the voice quality from the original Opus recording while keeping files small. Since the source material is only 16–32 kbps Opus, even 64 kbps MP3 captures everything without any loss. Going higher than 128 kbps is pointless — you cannot add detail that was never recorded.

Batch Converting Multiple Voice Messages

If you need to archive dozens or hundreds of voice messages, individual conversion becomes tedious. Here are efficient approaches:

• Online batch: Upload multiple .opus or .ogg files to Convertio.com at once. Convert them all in one session and download the MP3 results.
• FFmpeg batch (command line): Copy all voice files to a folder and run:
  for f in *.ogg; do ffmpeg -i "$f" -c:a libmp3lame -b:a 128k "${f%.ogg}.mp3"; done
  This converts every OGG file in the folder to MP3 in seconds.
• WhatsApp export: In WhatsApp, tap the three-dot menu in a chat → More → Export chat → Include media. This creates a ZIP archive containing all media files from the conversation, including voice messages. Unzip and batch convert the .opus files.

WhatsApp vs Telegram: Voice Message Differences

Both apps use the same codec, so the conversion process is identical. Upload the .ogg or .opus file, convert to MP3, and you are done.
