Glossary Of Photography Terms [1]

Lossless Compression Lossless compression is a data compression technique used to reduce the file size of digital images without sacrificing image quality or detail. Unlike lossy compression, which discards some image data during the compression process, lossless compression algorithms preserve all original image information, allowing the image to be reconstructed perfectly when decompressed. Lossless compression is achieved by identifying and encoding redundant or repetitive patterns within the image data, resulting in smaller file sizes while maintaining pixel-by-pixel accuracy and fidelity.

Lossless compression is commonly used in professional photography workflows, archival storage, and image editing applications where preserving maximum image quality is a priority. Examples of lossless compression formats include TIFF (Tagged Image File Format), PNG (Portable Network Graphics), and some variants of RAW image formats used by digital cameras.
