Transferring multimedia content between various messengers on the platform Android often raises questions among users, since there is no direct integration between these applications. Unlike social networks, mobile messengers operate in isolated environments (“sandboxes”), which prevents direct exchange of data through a simple “Share” button without intermediate actions. This was done for the purpose of data security and compliance with the privacy policies of the developers.
However, technically, the problem of how to send a video from Viber to WhatsApp from Android can be solved quite simply through the system file manager or the device gallery. You will not need third-party apps or complex manipulations with root access. The whole process comes down to correctly searching for the saved file in the smartphone’s memory and then sending it through the interface of another application. It is important to understand the difference between files stored in the device’s memory and those that remain only on the messenger servers.
In this article we will analyze in detail the algorithm of actions, features of video file compression and ways to bypass restrictions on the size of transferred data. We'll look at working with the phone's internal storage, privacy settings, and the nuances of transferring large amounts of information. Follow the instructions to quickly move the desired video from one chat to another without losing quality.
Why there is no direct “Share” button between messengers
Many users expect to see a button in the attachment menu that allows you to instantly transfer the video from Viber to WhatsApp. Unfortunately, such a function does not exist due to architectural differences and security policy operating system Android. Each application has access only to its own directories and shared media storage, but cannot directly manage the files of another running process.
In addition, the encryption protocols and metadata formats of these services differ. Messengers use different compression and encoding algorithms to optimize traffic. Direct transfer could result in decoding errors or file corruption. Therefore, the system requires that the file first be saved as an independent object in the phone's memory before another application can pick it up.
⚠️ Attention: If you try to use third-party "converter" apps from the Play Market that promise direct transfer, be careful. Most of them simply duplicate the function of a file manager, but may request redundant permissions to access your contacts and personal correspondence.
Thus, the only reliable and safe method is to manually save the file to the gallery or downloads folder. This action creates a physical copy of the video that is available to any other application that has permission to read the internal storage. This approach ensures that you send exactly the file that you see on the screen.
Preparing files and saving settings in Viber
Before you start transferring, you need to make sure that the video recording is actually saved in the internal storage of your smartphone. By default, settings Viber can be changed so that media files are downloaded only for viewing within the application and are not saved to the general gallery. This saves space, but complicates the transfer task.
To check and change settings, you need to go to the settings of the application itself. Find the section responsible for media and data. Here you will see a switch responsible for automatically saving photos and videos. If it is turned off, you will have to save files manually for each specific video before sending to another messenger.
- 📁 Open Viber and go to the section
More → Settings → Memory. - 💾 Activate option "Save to Gallery" to automatically copy all incoming and outgoing videos.
- 🖼️ If the option is disabled, open the chat, find the video, click on it and select the save icon (down arrow or three dots → Save).
After enabling this feature, all new videos will automatically appear in your phone's Gallery or Photos app in a separate album Viber. This greatly simplifies the process, since you do not need to search for the file through Explorer every time. However, it is worth remembering that this can quickly fill up your device if you are in active video chats. internal memory devices if you are in active video chats.
If your phone's memory is full, before enabling autosave, clear the messenger cache in Android settings to make room for new files.
Searching for video files through the system explorer
If automatic saving was not enabled in advance, or you need to find an old video, you will have to use the system file manager. On different smartphone models (Samsung, Xiaomi, Pixel), the Explorer interface may differ, but the folder layout logic remains the same for the entire ecosystem. Android.
You need to open the “Files”, “My Files” or “Explorer” application. Next you should go to the internal storage. The path to the messenger files may vary depending on the operating system version. On older versions of Android, the path was simple, but on new versions (Android 11 and higher), the directory structure became more complex due to restrictions on access to system folders.
Standard path for new versions of Android:
Android → media → com.viber.voip → Viber → Media → Viber Video
In older versions of the system, the folder could be located in the root of the internal storage along the path Viber → Viber Video. If you don't see the folder Viber immediately, try using the file search function inside Explorer by entering the extension .mp4 or part of the file name. This will allow you to filter out unnecessary documents and find the video you need.
| Android version | Folder location | Availability |
|---|---|---|
| Android 10 and below | /Internal memory/Viber/Viber Video |
Direct access |
| Android 11 - 13 | /Android/media/com.viber.voip/Viber/Media |
Restricted access |
| Android 14+ | Depends on the manufacturer's shell | Permission required |
When you find the file you want, hold it with your finger for a few seconds to select it. From the menu that appears, select the “Copy” or “Move” option. Copying is safer, since the original will remain in the Viber folder in case you want to send it to someone else from there.
☑️ Search for a video file
The process of sending through the WhatsApp interface
After the video has been found and copied to an accessible location (or if it is already in the gallery), you can proceed to sending. Open the application WhatsApp and go to the chat with the contact or group where you want to send the video. Click on the paperclip (attachment) icon in the text input field.
In the menu that opens, select “Gallery” or “Video”. The system will prompt you to select a file from recent ones or view all albums. If you previously copied the file to another folder through File Explorer, you may need to select the Document option to get to the desired directory, although usually the video is immediately displayed in the gallery.
Before sending, pay attention to the preview panel. Messenger by default it offers to compress the video for quick sending. If quality is critical, click the HD icon at the top of the screen before clicking the submit button. This will allow you to transfer the file with minimal loss of detail, although the file size will increase.
⚠️ Attention: When sent through the “Document” item, the video will not have a preview in the chat and will be compressed less, but the recipient will have to manually download the file to view. Sending via Gallery gives an instant preview, but applies more aggressive compression.
Once you have selected a file, click the send button (green arrow). The download process will take time depending on the size of the video and the speed of your Internet connection. Do not close the application before the download is complete, otherwise the transfer may be interrupted and you will have to start again.
What to do if the video is not sending?
If the sending freezes, check if the data saving mode is enabled in the WhatsApp settings. Also try switching from Wi-Fi to a mobile network or vice versa. Sometimes clearing the application cache in the phone settings helps.
Size limits and video compression
One of the main problems when sending videos is the file size limit. Developers WhatsApp set limits so as not to overload their servers and user communication channels. Currently, the maximum size of a video message sent as a media file is about 16 MB (depending on region and updates), and up to 2 GB when sent as a document.
If your video is from Viber weighs more than the permissible limit, the system will automatically offer to cut it or refuse to send it. In this case, you will have to use third-party video editors or online services to compress the file before uploading it to the messenger. There are applications that allow you to reduce the resolution or bitrate of a video without any visible loss of quality for your smartphone screen.
- ✂️ Use the built-in WhatsApp editor to trim long videos to the desired duration.
- 📉 Use video converters to reduce the resolution from 4K to 1080p or 720p.
- 📦 Send very large files as “Document” to bypass media compression limits (up to 2 GB).
It is worth considering that compression algorithms Viber and WhatsApp work differently. A video that has already been compressed in Viber, when re-processed in WhatsApp, can significantly lose quality, becoming blurry or “pixelated”. Therefore, if the source is important, always try to find the original file in the phone’s memory, and not send the version already processed by the messenger.
Sending a video as a “Document” preserves the original quality and bypasses limits on the size of media files, but deprives the recipient of the ability to quickly view without downloading.
Solving problems with access and permissions
Sometimes users are faced with a situation where WhatsApp simply “does not see” a video saved from Viber. This is a common problem on modern versions of Android, where the rules for application access to the file system have been tightened. If an application does not have explicit permission to read a specific memory section, it will not be able to display files in the list of attachments.
To solve this problem, you need to check the permission settings in Android itself. Go to Settings → Applications → WhatsApp → Permissions. Make sure access to Photos & Videos or Files & Media is set to Allow. Without this step, the messenger technically will not be able to read data from the folder where you saved the video.
The problem may also be related to the file format. Although MP4 is the standard, some codecs inside the container may not be supported by the WhatsApp player. If the file is not sent or is not played, try renaming the extension or converting the video to standard H.264 format using any available converter on your phone.
⚠️ Attention: Settings interfaces and menu item names may differ depending on the model of your smartphone (Samsung, Xiaomi, Honor, etc.) and the version of the manufacturer's shell. If you do not find the item you need, use the search in your phone settings.
In rare cases, rebooting the device helps. This updates the index of media files in the system, and the new video saved from Viber finally appears in the WhatsApp gallery. If all else fails, try manually moving the file to the folder DCIM → Camerathat WhatsApp scans first.
Why is the video sent with a black screen?
This happens when the video codec is not supported by the recipient's device or the messenger itself. Convert the video to MP4 (H.264) format before sending.
Frequently asked questions (FAQ)
Is it possible to send a video from Viber to WhatsApp without saving to the gallery?
No, technically this is not possible without intermediate saving. The file must exist as a separate object in the internal memory of the phone so that another application can access it and send it.
Why does it become poor quality after sending a video to WhatsApp?
WhatsApp automatically compresses the video to save traffic. To maintain quality, use the “Document” sending function or enable the HD option before sending in the preview window.
Where are videos from Viber on Android 13 and higher stored?
On new versions of Android, the files are usually located along the path: Internal memory → Android → media → com.viber.voip → Viber → Media → Viber Video.
How to send a video larger than 2 GB?
WhatsApp has a hard limit of 2 GB for any files. To transfer larger data, use cloud storage (Google Drive, Yandex.Disk) and send a link to the file in the chat.
Will a video disappear from Viber if I send it to WhatsApp?
No, the operation of copying or sending a file to another messenger does not in any way affect the original in Viber. The file will remain in the chat and in the phone memory unless you delete it manually.
