How to convert mkv to mp4 without losing quality in windows 11?

Make sure the converter supports the codecs in your MKV file. I once tried converting a high-bitrate 4K movie with an outdated tool, and it choked or gave me a corrupt MP4. Sometimes, the audio and video go out of sync after conversion. I’ve seen this happen when I tried custom settings. To avoid it, stick to default profiles or test a small clip first before converting the whole thing.

Converting MKV to MP4 can sometimes blow up the file size or make it too small. Be mindful of your output settings—don’t just pick the highest quality without considering the size. I learned this the hard way when my MP4 ended up way too big to store on my drive. Always keep your MKV file safe before you start. I’ve accidentally overwritten an original, and then I was bummed. Better safe than sorry, especially if you’re doing batch conversions.

Make sure the process of convertting MKV to MP4 completes fully. Interrupting it midway can corrupt your MP4. I’ve had to redo a few because my PC froze or I closed the app too early. Don’t download sketchy converters from shady sites—they might be bundled with malware.
