Lossless compression is a digital image-compression method that preserves all original image data. Formats such as TIFF or PNG use this type of compression, ensuring that when the image is decompressed, it is identical to the original version with no loss of detail or quality.
Understanding lossless compression is important for photographers, graphic designers, and digital archivists who require maximum image fidelity. This method is ideal for professional photography, archival storage, and situations where image quality cannot be compromised, such as high-resolution printing and scientific imaging.
