Forwarding voice messages between instant messengers is a task that many users face Android. Although Viber and WhatsApp do not have built-in functionality for direct audio file sharing, there are several workarounds. The main difficulty is that both applications store media files in protected folders, and their interfaces do not provide for exporting voice messages to other services.

In this article we will look 5 proven methodshow to save a voice message from Viber and send it to WhatsApp without loss quality. You will learn what tools are required (from standard functions Android to third-party applications), how to bypass the restrictions of instant messengers, and what nuances are important to consider when working with audio files. We will pay special attention to issues of security and confidentiality - after all, we are talking about personal data.

Why can’t you just forward a voice message directly?

At first glance, it seems strange that two popular instant messengers do not support file exchange with each other. The reasons lie in technical and business limitations:

  • 🔒 Closed ecosystems. Both Viberand WhatsApp strive to keep users inside their platform, so they do not provide APIs for integration with competitors.
  • 📁 Isolated storage. Voice messages are saved in folders /Android/media/com.viber.voip/ and /Android/media/com.whatsapp/, access to which is limited even for the file manager.
  • 🔄 Lack of the "Share" function. Unlike photos or videos, voice messages in both instant messengers do not have an export option through the menu Share.
  • 📱 Android Limitations. Starting from Android 10, accessing folders of other applications requires special permissions (MANAGE_EXTERNAL_STORAGE), which most file managers do not receive by default.

These restrictions force users to look for workarounds. Luckily, there are legal methods that don't require rooting or hacking system files. Next, we will look at them in detail - from the simplest to the most universal.

Method 1: Saving via the built-in Viber player

The most obvious (but not always working) method is to use the built-in player Viber. This method is suitable for short voice messages and does not require the installation of additional applications.

Action algorithm:

  1. Open the chat in Viber, where the desired voice message is located.
  2. Click on the message to start playing.
  3. An icon will appear in the upper right corner of the player three dots (⋮) - tap on it.
  4. In the menu, select the item Save (or Save, if the interface is on English).
  5. The file will be saved to the folder Downloads/Viber or Viber Media/Audio.

Now all that remains is to send the saved file via WhatsApp:

  1. Open the chat in WhatsAppwhere you need forward a message.
  2. Click on the paperclip icon (📎) in the input field.
  3. Select Document → find the folder Viber → select the saved audio file (usually has an extension .opus or .m4a).
  4. Send the file as a document.

☑️ Check before sending

Completed: 0 / 4

⚠️ Attention: This method does not work on all versions Viber. In some assemblies, the option Save may be missing or save the file in an unsupported format. If after saving the file is not played in the standard player Android, try the following method.

Method 2: Using a file manager with access to root folders

If the built-in saving did not work, you can manually copy the audio file from the folder Viber using a file manager Solid Explorer, FX File Manager or Total Commander.

Step by step instructions:

  1. Install one of the recommended file managers from Google Play.
  2. Open the manager and give it access to the storage (Allow access to files).
  3. Follow the path: 
    /storage/emulated/0/Android/media/com.viber.voip/audio/

    All voice messages are stored here from Viber.

  4. Find the file you need (they are usually named as audio_XXX.opus, where XXX is a unique identifier).
  5. Copy the file to any available folder (for example, Downloads).
  6. Open WhatsApp, select a chat and send the copied file as a document.

🔹 Advantages of the method:

  • 🔧 Works on all versions Viber i Android.
  • 📂 Allows you to save several files at the same time.
  • 🔄 Does not require an Internet connection (except for the sending itself to WhatsApp).

⚠️ Attention: On Android 11+ access to the folder /Android/media/ may be limited. If the file manager does not see the folder Viber, try using Solid Explorer with the option enabled Show hidden files or update the application to the latest version.

What to do if the file does not play in WhatsApp?

If the recipient cannot listen to the voice message after sending, the problem may be with the file format. Viber saves the audio in .opus format, which not all players support. Solution: use a converter (for example Audio Converter from Google Play) to convert the file to .mp3 or .m4a before sending.

Method 3: Record screen from playing a voice message

If the previous methods did not work, you can use a trick - record the playback of a voice message via screen recording. This method is universal, but requires additional manipulations.

What you will need:

  • 📱 Built-in screen recording function (available on Android 10+) or an application like AZ Screen Recorder.
  • 🔊 Sound on the phone (volume at maximum).
  • 🎧 Headphones with a microphone (optional, for better quality).

Instructions:

  1. Activate screen recording (via the notification shade or application).
  2. Open the voice message in Viber and play it.
  3. Stop recording after the end of the message.
  4. The video file will be saved in the gallery. Trim it using Google Photos or CapCut, leaving only the audio track.
  5. Send the resulting file as a video or extract audio from it using a converter. WhatsApp as video or extract audio from it using a converter.
Parameter Method 1 (built-in saving) Method 2 (file manager) Method 3 (screen recording)
Difficulty ⭐ (easy) ⭐⭐ (average) ⭐⭐⭐ (difficult)
Sound quality ✅ Original ✅ Original ⚠️ Possible losses
Internet required ❌ No ❌ No ❌ No (except for sending)
Additional applications ❌ No ✅ You need a file manager ✅ You need recording software

⚠️ Attention: When recording the screen, the sound may be recorded with distortion (echo, noise). To improve quality, play the message through your phone's speaker in a quiet room, or use headphones with a microphone connected to your phone.

💡

If you often send voice messages between instant messengers, create a shortcut for the folder on the main screen /Android/media/com.viber.voip/audio/. This will save time when searching for files.

Method 4: Using converter bots (Telegram)

If you need to not only forward, but also convert a voice message into a more universal format (for example, .mp3), you can use bots in Telegram. This method is suitable for users who have installed Telegram and access to the Internet.

The most popular bots for conversion:

  • 🤖 @VoiceMessageBot - saves voice messages from Viber/WhatsApp to .mp3.
  • 🤖 @AudioConverterBot - supports conversion v .mp3, .wav, .ogg.
  • 🤖 @FileConverterBot is a universal converter for audio and video.

How it works:

  1. Save the voice message from Viber by any of the previous methods.
  2. Open Telegram, find one of the bots (for example, @VoiceMessageBot).
  3. Send the saved audio file to the bot.
  4. The bot will return you the file in the format .mp3.
  5. Download the converted file and send it to WhatsApp.

🔹 Pros method:

  • 🔄 Conversion to a universal format .mp3, which is supported by all players.
  • 📱 Does not require installing additional applications on your phone (enough Telegram).
  • 🔒 Bots usually do not save your files after processing (check the privacy policy bot!).

⚠️ Attention: Some bots have file size limits (usually up to 50 MB). If your voice message is longer than 5-10 minutes, split it into parts or use another method.

Method 5: Automation through Tasker (for advanced users)

For those who often face the need to forward voice messages, you can set up an automatic system using Tasker or MacroDroid. This method requires initial knowledge about automation, but allows you to save time in the future.

What you will need:

  • 📱 Application Tasker (paid) or MacroDroid (free version with limitations).
  • 🔧 Module AutoInput (for Tasker) or permission to access notifications.
  • 📂 File manager with access to root folders.

Example macro for MacroDroid:

  1. Create a new macro with trigger Notification from Viber (filter by text "voice message").
  2. Add action Copy file: 
    Source: /Android/media/com.viber.voip/audio/audio_*.opus

    Destination: /Downloads/Viber_Audio/

  3. Add an action Open WhatsApp with a pre-selected chat.
  4. Add action Share file from folder /Downloads/Viber_Audio/.

🔹 Advantages of automation:

  • ⚡ Instant transfer without manual actions.
  • 🔄 Ability to convert files on the fly.
  • 📈 Suitable for regular use (for example, for work).

⚠️ Attention: Setting up Tasker or MacroDroid may take time, and incorrectly created macros can disrupt operation messengers. Before using, test the automation on unnecessary files.

💡

For one-time forwarding of a voice message, methods 1-2 are sufficient. Automation (method 5) is justified only if used regularly.

Comparison of methods: which one to choose?

The choice of method depends on your needs, technical skills and version Android. Below is a brief comparison:

Criteria Best choice
Maximum simplicity Method 1 (built-in saving in Viber)
University (works on everyone versions) Method 2 (file manager)
Conversion to .mp3 Method 4 (Telegram bots)
Regular use Method 5 (automation via Tasker)
Minimal quality loss Methods 1–2 (direct file copying)

If you are not sure which method to start with, try them in the following order:

  1. Method 1 (built-in saving).
  2. Method 2 (file manager).
  3. Method 4 (bots in Telegramif conversion is needed).

Methods 3 and 5 should be considered only in extreme cases or for specific tasks.

Common mistakes and how to avoid them

When sending voice messages, users often encounter typical problems. Here are the most common of them and ways to solve them:

  • 🔊 The file does not play in WhatsApp. Reason: format .opus is not supported. Solution: convert the file to .mp3 using Audio Converter or bots to Telegram.
  • 📂 I don’t see the Viber folder in the file manager. Reason: restrictions Android 11+. Solution: use Solid Explorer with root access or enable the display of hidden folders.
  • 🔒 WhatsApp does not allow you to send the file. Reason: Size limit (usually 16-100 MB). Solution: trim the audio or compress it using MP3 Compressor.
  • 📱 After sending, the sound quality deteriorated. Reason: Multiple conversion or screen recording. Solution: Use direct file transfer (method 1 or 2).
  • ⚠️ The recipient cannot download the file. Reason: slow Internet or restrictions on the recipient's side. Solution: upload the file to the cloud (Google Drive, Dropbox) and send the link.

If none of the methods worked, check:

  • Are they updated? Viber and WhatsApp up to the latest versions.
  • Is there enough free space on the device (voice messages can take up to several megabytes).
  • Does the antivirus block access to messenger folders.
💡

If you often work with audio files, install the application VLC for Android. It supports playback of .opus and .m4a formats, and also has a built-in converter.

Is it possible to forward a voice message from Viber to WhatsApp without saving it to your phone?

No, both messengers do not support direct file exchange with each other. You will definitely need to intermediately save the audio file to your device or to the cloud. The exception is the use of bots (method 4), but in this case the file is temporarily saved on the bot server.

Why is a voice message sent as a document in WhatsApp and not as audio?

WhatsApp automatically detects the file type by extension. If the file has the format .opus or .m4a, the messenger can recognize it as a document. To send as audio, rename the file to .mp3 or use conversion.

Is it safe to use bots in Telegram to convert voice messages?

Most popular bots (for example, @VoiceMessageBot) do not save user files after processing. However, to be sure, check the bot's privacy policy and avoid sending sensitive audio recordings. An alternative is local converters like Audio Converter.

Is it possible to forward a voice message from iPhone to Android?

Yes, the algorithm is similar, but there are nuances:

  • On iPhone messenger folders are even more isolated. Use iMazing or iExplorer to access files Viber.
  • For conversion, the same bots to Telegram or applications like MediaConverter from App Store.
  • When sending in WhatsApp on Android make sure that the file is in a compatible format (.mp3, .m4a).
How to forward a voice message from Viber to WhatsApp on a computer?

On a PC the algorithm is as follows:

  1. Download Viber for Windows/macOS and find the folder with audio files (usually C:\Users\UserName\AppData\Roaming\ViberPC\\audio\).
  2. Copy the desired file to your desktop table.
  3. Open WhatsApp Web (web.whatsapp.com), select the chat and drag the audio file into the conversation window.

If WhatsApp Web does not accept the file, convert it to .mp3 s using Audacity or online services.
