Frequently Asked Questions
What is MKV and why convert to MP4?
MKV (Matroska Video) is a flexible container format popular for high-quality video. However, many devices, smart TVs, and social media platforms do not natively support MKV. Converting to MP4 ensures your video plays everywhere.
Will I lose video quality converting MKV to MP4?
There is minimal quality loss. The converter uses H.264 video encoding with AAC audio, which is the industry standard. The output is optimized for broad compatibility while maintaining excellent quality.
Can I play the MP4 on my phone or smart TV?
Yes! MP4 (H.264) is universally supported by iPhones, Android devices, smart TVs, game consoles, and every major media player. This is one of the main advantages of converting from MKV.
What about subtitles in my MKV file?
MKV files often contain embedded subtitle tracks. During conversion, the video and audio streams are re-encoded but embedded subtitle tracks are not carried over. You may need to use the subtitles as a separate SRT file.
How long does conversion take?
It depends on the file size and your device speed. A 1-minute clip typically converts in 15-45 seconds. MKV files can be large, so longer videos will take more time as all processing runs in your browser.
Is my video uploaded to a server?
No. Everything runs locally in your browser using WebAssembly technology. Your video file never leaves your device, ensuring complete privacy.
