Arithmetic encoding: This encodes the whole file as a series of characters with symbols assigned to them.Huffman coding: This algorithm assigns different values to characters and their frequencies.These are some of the most common algorithms used: Why Should You Use Lossless Compression?Īs we mentioned earlier, lossless compression uses an algorithm to compress images and other file types. Streaming giants Spotify, Apple Music, and TIDAL use this method to speed up content loading without reducing music quality. These are the most common lossless file formats:įurthermore, lossless compression is increasingly used for audio files. Lossless compression is most suitable for photos with transparent backgrounds and images with a lot of text. Therefore, this compression method creates more streamlined files without deleting their extra information. It also strips metadata from your images.

Then, it replaces this information with numbers and stores the original data in a separate index file. Lossless compression uses an algorithm that looks for repetitions of words, patterns, and other unnecessary data. However, the file has been made 12.24 percent smaller. It has been reduced in file size from 335KB to 294KB:Īs you can probably see, there is no discernible difference in image quality. It is also completely reversible.įor example, here is an image with lossless compression applied to the right side. This method can make files smaller without affecting their overall quality. Lossless compression can reduce file sizes by removing and isolating redundant data. Let’s get started! What Is Lossless Compression? Then we’ll explain how to apply this compression method to your images and files. In this guide, we’ll explore lossless compression and when you should use it. Fortunately, lossless compression can reduce file sizes without affecting their quality. However, including too many “heavy” elements could slow down your site and affect its overall performance. Using images, videos, and other files can improve the quality of your blog posts and enhance your WordPress website’s appearance.
