Good day, dear readers of my blog. To say that today's experiment surprised me to say nothing. You just can't imagine how amazing it is to do a little "lab" study on video conversion.

It is clear that anyone working on the Internet wants to create high-quality, small videos. This significantly reduces the download speed. If the video is made for the site, this is even more relevant because the file has a lower load on the server. In addition, a large document is much more difficult to transmit over the Internet, as this time is also relevant for regular users.

By converting and compressing files, you can get space. These methods reduce the need for space. Movie users collect hundreds of valuable videos, graphics of thousands of image files, office users of important office documents. But even home sound recordings absorb space. If you need more memory, you have two options: lossless compression or file optimization.

Do you think how to make a MP4 file smaller to store on your PC, compress mp4, reduce mp4 size, or lighten mp4 to save PC memory? Here, we will show you various ways to reduce MP4 size on Windows and Mac, and also recommend free and easy video reduction software!

MP4 is a popular file format because it is compatible with almost all smartphones, tablets, physical media or media players. As I continued to save videos, movies, tutorial videos, etc. downloaded from video sites such as YouTube to the HDD of my computer one after another, the memory space of the HDD became low. Besides, the operating speed of the personal computer may slow down.

However, I love the saved MP4 videos and want to cherish them, so I can't delete them. In this case, start looking for ways to reduce MP4 size, mp4 compression, mp4 lighter, that is, reduce video capacity.

To reduce the size of MP4 video files, it is widely used to reduce the bit rate and use tools for MP4 compression. There are many MP4 size down tools online, among them free software that reduces MP4 capacity but does not significantly reduce quality.
