Understanding File Compression

File compression is the process of reducing the size of one or more files or folders. This is achieved by using various algorithms that eliminate redundancy, thereby making the files smaller without losing their original quality. There are two primary types of file compression: lossless and lossy.

  1. Lossless Compression: This type of compression reduces file size without any loss of data. The original file can be perfectly reconstructed from the compressed file. Common formats include ZIP, RAR, and 7z. Lossless compression is ideal for text documents, software, and any data where preserving the exact original content is crucial.

  2. Lossy Compression: In contrast, lossy compression reduces file size by permanently eliminating certain information, especially redundant data. While this can significantly reduce file size, it can also degrade quality. This type is commonly used for multimedia files such as images, audio, and video. Formats include JPEG for images, MP3 for audio, and MP4 for video.
