Videos take up a lot of space, especially as the resolution has progressed over the years. We went from a modest 360p to 4K in a short period. The video quality comes with a bigger file size.

Uploading and downloading a video of enormous size is a headache, to begin with. Copying it to a flash drive/external HDD is also time-consuming. Storing it in your already full partitions is another story altogether.

Reducing video size can help in various ways. When doing that without prior knowledge, you would compromise the video quality. That’s not on the table, as the quality is of umpteen importance.

Even a video editor can sabotage the quality by rendering and exporting it with an underwhelming set of codecs. This is why you need a dedicated video converter that can reduce video size without losing quality.
