Frequently Asked Questions

Why convert MKV to MP4?
MKV is a brilliant container format, but it struggles with native support on many devices like iPhones, iPads, smart TVs, and gaming consoles. MP4 is accepted everywhere—whether you're streaming on a TV in Melbourne or watching on your phone in Perth—ensuring seamless playback.
Will converting MKV to MP4 lose quality?
If both MKV and MP4 use the H.264 codec, the conversion is essentially a container swap with negligible quality loss. Our converter uses high-quality encoding settings to keep your footage looking sharp.
What about subtitles and multiple audio tracks in MKV?
MKV supports multiple audio and subtitle tracks, whereas MP4 is a bit more limited. Our tool includes the primary audio and video. If you need to preserve commentary tracks or multiple languages, it's best to keep the original MKV as a backup.
What is the maximum file size?
You can convert MKV videos up to 50MB. Since high-quality MKV files can be quite large, you might need to convert shorter clips or compress the resolution for longer movies.
Are my videos safe and private?
Absolutely! All conversion happens locally in your web browser. Your videos are never uploaded to a server. Once you close the tab, all data is permanently deleted from your device.
