A compression technique that decompresses data back to its original form without any integrity loss, as all pixel data is retained. The decompressed file and the original are identical. All compression methods used to compress text, databases, and other business data are lossless. For example, the ZIP archiving technology (PKZIP, WinZip, etc.) is the most widely used lossless method. Lossless compression is recommended for high-contrast images, line art, and text.
