Where are WhatsApp voice notes stored?

WhatsApp is the world’s most popular messaging app, with over 2 billion users globally. The ability to send voice messages or “voice notes” has been a feature of WhatsApp since 2013. Voice notes allow users to quickly record and send brief audio clips to contacts or groups. This provides a more natural and personal way of communicating compared to typing out messages. The voice notes function has proven extremely popular, especially in regions where literacy rates are lower. Over the years, people have found creative ways to use WhatsApp voice notes for language learning, storytelling, remote work communication, and more.

Voice Notes Overview

WhatsApp launched voice messages in 2013, allowing users to exchange short audio recordings with contacts instead of typing messages. Voice notes work similarly to sending a voice message on a phone – the user presses and holds the microphone icon in WhatsApp to record, then lifts their finger to stop. This records an audio clip that is then sent to the recipient as a voice message within WhatsApp [1].

Voice notes have become an extremely popular way of communicating quickly and easily on WhatsApp. They allow users to convey emotion and emphasis through their voice, and avoid the hassle of typing long messages. Voice notes are especially useful for visually impaired users, those with limited literacy, or when a user’s hands are occupied. Overall, the voice note feature makes communication via WhatsApp more flexible and personal.

Voice Note Storage on Phone

On Android devices, WhatsApp voice notes are stored in the WhatsApp/Media/WhatsApp Voice Notes folder. The full file path is typically something like: Internal Storage/WhatsApp/Media/WhatsApp Voice Notes.

On iPhones, WhatsApp voice notes are stored in the Media/WhatsApp Voice Notes folder. The full file path is typically: Internal Storage/Media/WhatsApp Voice Notes.

So in both Android and iOS devices, WhatsApp stores voice notes locally in a dedicated WhatsApp Voice Notes folder. This folder can be accessed through the phone’s file manager app.

In Android devices, users can also access voice notes from within WhatsApp by going to Settings > Data and Storage Usage > Media Auto Download. There is an option to view WhatsApp Audio files from here.

On iPhones, users can access all WhatsApp media including voice notes from Settings > Data and Storage Usage > Media. The voice notes will be under the WhatsApp Voice Notes tab.

Voice Note Storage on WhatsApp Server

When you first send or receive a voice note on WhatsApp, it is temporarily stored encrypted on WhatsApp’s servers [1]. This allows the voice note to be delivered to the recipient even if their phone is offline. The encryption means that the voice note content remains private and cannot be accessed by anyone apart from the sender and recipient.

WhatsApp states that after delivering the voice note, it may retain some data for a short period before deleting it from its servers [1]. However, the voice note content itself is not stored. Only basic metadata like the date, time, and sender/recipient may be retained for a short time.

Therefore, WhatsApp servers provide temporary encrypted storage to deliver voice notes, but the content is not permanently stored on their servers. The voice note audio files reside on the sender’s and recipient’s phones once delivered.

Media Automatically Downloaded

By default, WhatsApp will automatically download voice notes and other media files sent to you over WhatsApp. However, you can control these auto-download settings for voice notes specifically.

On Android, open WhatsApp Settings > Data and Storage Usage. From here, you can toggle off “Auto-download voice notes” to prevent voice notes from automatically saving to your device when using mobile data or WiFi.

On iPhone, open WhatsApp Settings > Cellular Data Usage. Toggle off “Use Cellular Data for Voice Messages” to disable auto-download of voice notes on cellular data. You can also go to Settings > WiFi > Use WiFi Only For and disable voice notes here to prevent auto-download on WiFi.

Disabling auto-download for voice notes prevents them from being automatically stored on your device. You would need to manually download each voice note to save it locally.

Backing Up Voice Notes

Backing up your WhatsApp voice notes helps ensure you don’t lose any important messages if you get a new phone or for any other reason. There are a few ways to back up your WhatsApp voice messages:

The easiest way is to back up your chat history to Google Drive. WhatsApp has a built-in chat backup feature that saves your messages, media, voice notes and more to your Google account. To enable it, open WhatsApp Settings > Chats > Chat Backup > Back Up to Google Drive. You can configure it to back up daily, weekly or monthly. Your voice notes will be included in these backups automatically.

You can also back up your voice notes locally to your phone’s storage. Open WhatsApp Settings > Chats > Chat Backup > Back Up to Local Storage. This will save a backup file to your phone that you can transfer to a computer if needed.

On iPhone, you can back up your WhatsApp data, including voice notes, to iCloud by enabling iCloud Backup in your iPhone settings. Android also allows local backups to external SD cards.

Finally, you can manually export voice notes by forwarding them to your own phone number or saving them to another app. Just open the chat, long press the voice note, and select Forward. This isn’t the most efficient backup method but works in a pinch.

Following these tips will ensure your important voice messages are secured in case you ever need to access them again later.

Deleting Voice Notes

To delete a voice note you have received in WhatsApp, you can simply long press on the voice note and tap the trash icon. This will delete the voice note from your chat. According to the WhatsApp FAQ, to delete a voice note:

  1. Tap and hold the voice note.
  2. Tap the trash icon to delete it.

You can also select multiple voice notes to delete them all at once. Deleted voice notes will be removed from your phone’s storage as well. However, if the voice note was already downloaded before you deleted it, the file may still be accessible in your phone’s file manager app depending on your device. But it will no longer be available or playable within WhatsApp.

If you want to delete a voice note for all participants in the chat, you can tap and hold the voice note, then choose “Delete for everyone” instead of just “Delete.” This will remove the voice note entirely from the chat history. However, you only have a limited time to delete a message for everyone (up to 1 hour 8 minutes) before the option disappears.

According to the WhatsApp FAQ: “Deleting messages for everyone allows you to delete specific messages you’ve sent to an individual or group chat. This will remove the message for all participants. You can only delete messages for everyone for up to 1 hour, 8 minutes, and 16 seconds after sending the message.” (Source)

Voice Note File Formats

WhatsApp uses the Opus audio codec to encode voice notes. Opus is an open and royalty-free audio coding format designed for both speech and music transmission over the Internet (Source).

The file name format for WhatsApp voice notes is PTT-YYYYMMDD-WAXXXX.opus. This consists of:

  • PTT – Stands for “Push to Talk”
  • YYYYMMDD – The date the voice note was recorded
  • WAXXXX – A unique ID for each voice note
  • .opus – The file extension indicating Opus codec

When you download a WhatsApp voice note on your phone, it will be saved in Opus format. To convert it to a more common format like MP3, you need to use a third-party app or converter (Source).

Voice Note Size Limits

WhatsApp does not officially specify a maximum length for voice notes. However, based on user reports, voice notes are limited to about 16 minutes and 38 seconds or 100 MB in size, whichever limit is reached first.

According to discussions on Reddit and Quora, users have found through experience that attempting to send a voice note longer than 16-17 minutes results in failure to send. The file size also seems to be capped at around 100 MB.

So in practical terms, the maximum voice note length on WhatsApp is approximately 16 minutes and 38 seconds or 100 MB.

This limit applies across devices and operating systems, including Android, iPhone, and Windows Phone.

While there is no official documentation from WhatsApp on the voice note size restrictions, these practical limits reported by users can be helpful to keep in mind when recording long voice messages.


In summary, WhatsApp voice notes are stored locally on a user’s device and temporarily on WhatsApp’s servers when sending and receiving. The audio files are automatically downloaded when received and can be backed up either manually or automatically to a user’s Google Drive or iCloud account. While there are size limits, voice notes utilize optimized audio formats to conserve storage space. Users can manage voice notes by deleting old ones or backing them up externally as needed.

To recap, WhatsApp voice notes provide a convenient way to communicate with audio messages. The audio files are accessible on a user’s device like any other media file when not actively being sent or received. With automatic backups and file management, users can easily save important voice notes or delete old ones as desired.
