Process of reducing the size of a file

Detailed explanation-1: -Compression reduces the size of a file, often without appreciable loss of information. It can be either lossless or lossy. A smaller-sized compressed file can be restored to its larger form–in its entirety or with some data loss, depending on the compression type–by decompression.
Detailed explanation-2: -By compressing a file, data takes up less space, and files can be sent and received a lot more quickly.
Detailed explanation-3: -File compression is a type of data compression that creates a smaller version of a file to allow for easier sharing over a network or internet connection. Generally, it will have a greater impact on image-based PDFs or image files like JPEGs and PNGs, rather than text-only documents.
Detailed explanation-4: -Definition(s): A file reduced in size through the application of a compression algorithm, commonly performed to save disk space. The act of compressing a file makes it unreadable to most programs until the file is uncompressed.
