MKV to MP4 Converter

Convert video on your device. Codec support affects compatibility; choose quality, bitrate and audio after selecting a file. Re-encoding may change quality and large files need time and memory. A requested file size is not guaranteed.

Files, text, edits and results are processed on your device and kept only in the open page. They are not uploaded for processing. Reloading or closing the page clears the workspace. Files you download to your device remain there until you delete them.

MKV to MP4 is perfect when you have an MKV file that won’t play on certain devices or won’t upload to certain platforms. MP4 is widely accepted and easy to share.

If you want a smaller web-first output, convert to MP4 first, then consider MP4 to WebM.
