How do I make an MKV file smaller?

Why are MKV files so big?

An MKV file is typically larger than an MP4 because it can contain multiple audio and subtitle tracks. You may notice that when you save a video as MKV, you will end up with a larger file size than when you save the same video as MP4.

How do I convert from MKV to MP4?

VEED automatically converts your MKV videos to MP4 format after compression. You can also convert your MKV files (without compressing them) by uploading to VEED and simply hitting the ‘Export’ button.

Will I lose image quality if I convert my MKV file to MP4?

No. Converting an MKV file to MP4 will not result in loss in image quality. Both MKV and MP4 are ‘container’ formats which means they can ‘contain’ and play the same video and audio in the same resolution.

How can I send a large MKV file via email?

Mail servers tend to limit the file attachments you can send between 20 and 25MB. It’s best to compress your MKV videos before sending them.
