lossless compression
Lossless compression is a method of reducing the size of a file without losing any information, so the original data can be perfectly restored when decompressed. It works by identifying and efficiently encoding repeating patterns or redundant data within the file. Common in text, spreadsheets, and certain image formats, lossless compression ensures that every detail remains intact, making it ideal for situations where accuracy is crucial. Examples include ZIP files and PNG images, which compress data without sacrificing quality. This process balances smaller storage/use with complete data integrity.
