What main feature distinguishes a Lossless Compression from a Lossy Compression?

Lossless compression is characterized by its ability to reduce file size without sacrificing any quality of the original data. This means that when the data is decompressed, it will be identical to the original, ensuring that no information has been lost in the process. This type of compression is crucial for applications where preserving the exact quality of data is necessary, such as in text files, certain image formats, and audio files where every detail is essential.

The other features mentioned in the options serve different purposes or characteristics. While options related to higher quality and larger sizes pertain to the nature of lossy compression—where some data is permanently removed to achieve smaller file sizes—they do not define the distinction of lossless compression. Additionally, while the elimination of redundant data is a technique used in both types of compression, it is not exclusive to lossless compression and does not capture the essence of maintaining original quality.
