Simply put, lossless compression stores the same information in a more efficient way by removing redundancy.

But how does this type of file compression reduce file size?

Stated another way, there is no detail or content lost in the compression-decompression process and you can perfectly reconstruct the original file. Lossless: By this type of file compression, a decompressed file has the same size as the original file. There are two types of compression algorithm: Why does a file become smaller after compression? Do you know the working principle of file compression? File compression utilizes compression algorithm that is a mathematical formula used in compression and decompression of an electronic data file. So, compressing a file will retrieve the space on a storage drive. When you execute file expression, the compressed files often take up 50% to 90% less disk space than the original files. What is file compression? File compression is the act of reducing the size of a file while preserving the original data. This could help you understand why you enjoy the following benefits after file compression. What can you benefit from compressing a file? But before showing the advantages of file compression, let’s try to understand “how does file compression work” first. In today’s post, I would like to talk about “ what does a compressing a file do”. With the development of the Internet, the need for creating better compression schemes and reducing the size of files as much as possible keeps climbing. In the 1970s, computer scientists strived to find ways to reduce the file size and they succeeded-searching through computer code by using mathematical algorithms. tar, etc.įile compression can be date back to about half a century ago. Speaking of compressing a file, most of us are no strangers to that.
