Frequently Asked Questions

Why convert MKV to MP4?
MKV is an excellent container format but lacks native support on many devices including iPhones, iPads, smart TVs, and game consoles. MP4 is universally supported across all devices, operating systems, and web browsers for seamless playback anywhere.
Will converting MKV to MP4 lose quality?
If both MKV and MP4 use H.264 video codec, the conversion is mostly a container change with minimal quality impact. Our converter uses high-quality encoding settings to preserve the best possible quality during conversion.
What about subtitles and multiple audio tracks in MKV?
MKV supports multiple audio tracks and subtitles, but MP4 has more limited support. Our converter includes the primary audio and video streams. For multi-track preservation, we recommend keeping the original MKV as an archive.
What is the maximum file size?
You can convert MKV videos up to 50MB in size. Since MKV files can be very large with high-quality content, you may need to convert shorter clips or lower resolution files.
Are my videos safe and private?
Absolutely! All MKV to MP4 conversion happens locally in your web browser. Your videos never upload to any server. Once you close the page, all data is permanently deleted.
