Compression differs from archiving in that it compresses stronger files, but cannot be seen without zipping in a special program. When compressed, files are not compressed too much, but can be seen and transferred in any format. Compression is now popular, because many people want to have lots of videos on the computer and on the phone, can watch it at any time, but it doesn't take up much space.

Besides the fact that you might need to compress video file so it doesn't store large file on your computer or cell phone, there are a number of reasons why you might need to compress or reduce video size in other ways.

- To send by email or download to a file hosting service. It takes time to upload videos to a file hosting service or attach them to an email. And sometimes it's faster to compress a video and then add smaller copies than to load a large file.

- To upload to YouTube. Now this is the most popular site for downloading and watching videos. However, to upload videos to the site, you need a lot of time. If you don't want to wait, you can quickly compress the video without losing quality, and then upload the reduced version to video hosting. Even if you have time - in some cases, YouTube may not allow you to upload videos that are too large. Then the problem will be solved by compressing or changing the file format.

- To carry external media. Sometimes the flash drive is too small to record video in it, or there is too little space in it and nothing can be deleted. When compressed, the size is reduced - and it is possible to write to external media.

- To watch videos on a smartphone. On some smartphones, the screen is too small to comfortably watch large format videos. Also, some phones do not support large video sizes. If you want to watch videos on your mobile - you can simply compress videos online - and drop them yourself, then you can watch them on any phone without problems.
