Typically, depending on the image, lossless compression ratios range from about 1.5:1 to 3:1. On the other hand, state-of-the-art lossy compression techniques give compression rations in excess of 20:1 with virtually no loss in visual fidelity.

What are examples of lossless compression?
Lossless compression methods are reversible. Examples of lossless compression include GZIP, Brotli, WebP, and PNG, Lossy compression, on the other hand, uses inexact approximations by discarding some data from the original file, making it an irreversible compression method.
What is the best lossless compression?
ZIP and RAR are popular lossless file formats for file compression. In a web context, GZIP compression is often used to make JavaScript and CSS files smaller. In image compression, PNG is a well-known lossless format.
What are different lossless compression methods?
The algorithms used in lossless compression are: Run Length Encoding. Lempel-Ziv-Welch (LZW) Huffman Coding.
What is a good compression ratio percentage?
Tests have shown that a compression ratio between 85% and 95% can be achieved for highly compressible data.
