What Is File Decompression?

File decompression is the process of restoring a compressed file to its original, uncompressed state. Compression reduces the size of files or data archives for efficient storage, speeding up file transfers over the internet and bundling multiple files into a single compressed archive for easier management. Decompression is the process of restoring compressed data to its original form.

There are various compression algorithms and formats, each with its own method of reducing file size. To decompress a file, you need a corresponding decompression tool.
