Brotli Compression vs GZIP CompressionĪs mentioned, both Brotli and GZIP use the DEFLATE method to compress (and decompress) data. In the next section, we’ll talk about what makes Brotli stand out. From there, an INFLATE process will decompress the files again when necessary.Īlthough Brotli is currently GZIP’s main contender, there are other similar technologies out there that also use DEFLATE. In short, uncompressed files run through the LZ77 and Huffman algorithms as part of the DEFLATE process to compress them into a Brotli format. It’s something we go into with extreme depth in our post on GZIP compression. In fact, if you combine these two technologies, you get the DEFLATE format that serves as the foundation for both GZIP and Brotli compressions. The company is often at the forefront of web-advancing technology, so it’s no surprise that Brotli looks to take what GZIP does, improve on it, and offer an enhanced experience to users and sites.īrotli compression uses the same core base technologies as GZIP compression, namely: It provides “lossless” compression and is developed by Google under an MIT license. However, if this is all we’d have to say, there would be no reason to investigate it. In a nutshell, Brotli is a data compression algorithm. We’ll talk more about why an alternative should exist later, but first let’s introduce you to GZIP’s “competitor.” Brotli Compression But up until now there were no real alternatives. GZIP compression is a standard way to minimize the size of bundles of files - think packages such as ZIP or Linux. For example, images often take lots of compression to reduce in size without much degradation of the image itself: An example of an optimized image. You’ll find that other file types have ways to compress data. However, the fundamentals of what this code does are still the same. If you minimize this code, it looks completely different: define( 'WP_INSTALLING', true ) /** Sets up the WordPress Environment. What’s more, these batches of whitespace and line breaks will take up precious room that, removed, can give you a performance boost. The above code uses elements like spaces and carriage returns to make it human-readable, but a computer doesn’t need these to understand the core code. $valid_error_codes = array( 'already_active', 'blog_taken' ) For example, take this suite of code: define( 'WP_INSTALLING', true ) However, it does make things more straightforward for the computers that have to compile and render the code. Removing these elements doesn’t affect the user experience (UX) in most situations. Ready to look into Brotli compression and see how to enable it on your own site? □ The answers are here □ Click to Tweet The idea is that aspects such as indents, comments, whitespace, and more will increase file sizes, and therefore loading times. You’ll find there are lots of ways to compress the data depending on the file type you’re working with.Ī common approach is “minification.” This is where an algorithm strips your site’s code of some of its superfluous elements. This gives you lighter files to move around the web and reduces the time it takes to load and render a website. In its most basic form, data compression takes the code for a website or app, and minimizes the file size. First, we’re going to place Brotli within the compression algorithm space, and talk about why you’d want to use it over other solutions. Check Out Our Video Guide to Brotli Compressionįor this tutorial, we’re going to look into Brotli compression and show you how to check whether your site uses it, and how to enable it if you need to. The details in this article will go into exactly what the technology offers, but Brotli compression is fast and efficient - which ticks all the boxes you need to investigate it. It’s a Google-developed solution that looks to provide a number of benefits over (as well as an alternative to) GZIP compression. GZIP compression is one way to do this, but Brotli compression is an alternative fledgling method that commands attention. One approach is to minimize the underlying code your site will use without affecting how it functions. In the web’s pursuit of fast loading times, we have a number of different technologies to help us. ![]()
