Yes, you can easily convert MKV to MP4 using WALTR PRO, which offers the fastest and most seamless way to transfer videos to your iPhone, iPad, or Mac. Unlike VLC or online converters, WALTR PRO automatically converts MKV to MP4 with no quality loss and direct playback in the native Videos app.

How to Convert MKV to MP4?

Let’s start by understanding what MKV and MP4 formats are. MKV (Matroska Video) is a powerful file format capable of storing multiple video, audio, and subtitle tracks. However, it is not natively supported on Apple devices, making it difficult to play on Mac, iPhone, or iPad without third-party apps. MP4, on the other hand, is widely compatible with Apple’s ecosystem and other devices.

Key Benefits of MP4 Over MKV:

• Universal Compatibility – MP4 files work seamlessly on most devices, including iPhones, Android phones, Smart TVs, and video players like VLC and Windows Media Player.
• Smaller File Size – Better compression (like MPEG4 and H.264) ensures high-quality videos with less storage.
• Streaming-Friendly – Preferred format for YouTube, TikTok, and Vimeo.
• Optimized for Apple Devices – Plays smoothly on QuickTime, without extra apps.

Now, let’s explore the best way to convert MKV to MP4 quickly and easily using WALTR PRO.
