Lossless compression tools generally use either Huffman coding or Lempel-Ziv-Welch (LZW) coding. Supports a large number of colors -- the format is suitable for different types of digital images, including photographs and graphics. That said, compressed TIFF files can be slightly slower to work with because they require more processing effort to open and close them. While you can choose between large, medium, and small file sizes, the result is very similar as they’re all lossless compression options. Compression reduces the size of a file, often without appreciable loss of information. An approach can be considered based on the acceptable quality and size of the output data. Lossless reduces file size by removing unnecessary metadata. Lossless compression results in a closer representation of the original media, and thus a higher quality end product. This compression results in smaller file sizes, typically around 50-60% smaller than the original WAV file. Since then, they’ve become widely used and accepted as a standard image format.
