Convert MKV to MP4 on Android
Master the complete Android workflow for converting MKV videos to MP4 format. This comprehensive guide covers browser conversion, file management, offline apps, and performance tips for all Android devices from phones to tablets.
Android Conversion Quick Start
Get your first MKV to MP4 conversion done in minutes using Chrome and your file manager.
Find your MKV file in Downloads, Gallery, or file manager. Make sure it's accessible to your browser for upload.
Open Chrome, visit our converter, select the MKV file. Keep the browser active and avoid switching apps during conversion.
Download the MP4, then share to Gallery, Google Drive, or other apps. Use the Downloads notification for quick access.
Method 1: Chrome Browser Workflow
Best for most Android devices with reliable internet connection and standard file sizes.
- Connect to Wi-Fi or ensure you have sufficient mobile data. Disable data saver mode in Chrome settings temporarily.
- Open mkv.to in Chrome, scroll to the converter section, and tap Select File.
- Choose your MKV file from Downloads, Internal storage, or cloud storage. Grant file access permission if prompted.
- Tap Start Conversion. Keep Chrome in the foreground to prevent Android from suspending the tab.

Troubleshooting Android Issues
Solve common problems when converting MKV to MP4 on Android devices.
Browser tab gets refreshed or killed
Enable "Desktop Site" mode in Chrome, disable battery optimization for Chrome, and keep the app in foreground. Consider using Chrome Beta for better memory management.
File upload fails or shows permission error
Grant storage permissions to your browser, try moving the MKV to Downloads folder first, or use a different file manager to access the file.
Conversion is very slow on older devices
Try reducing video quality settings, use an offline app instead of browser conversion, or consider using a desktop computer for large files.
Download fails or MP4 file is corrupted
Clear browser cache and cookies, try a different download location, or restart the conversion with a more stable internet connection.
Converted MP4 won't play in gallery
Install VLC or MX Player for better codec support, or try re-converting with different quality settings. Some gallery apps have limited format support.
App crashes during large file conversion
Free up RAM by closing other apps, restart your device before conversion, or split large files into smaller segments first.
