"Web29 ian. 2014 · On 8-bit TIFF files the difference in file size between LZW and ZIP is negligible, but ZIP takes 2-3x as long to save. On 16-bit TIFF files LZW often makes files that are larger than both ZIP or uncompressed TIFF files, so if you're going to use compression on 16-bit TIFF files skip LZW and use ZIP instead.
