![]() Compression speed – this is how quickly it takes to compress and decompress the file.Compression ratio – this is how big the file size savings are.Here, we’ll turn to some public benchmark tests.īefore we dig into the data, it’s important to understand that there are multiple parts to compression and web performance: Ok – now for the important question: Brotli vs GZIP compression – which performs better? ![]() Level 11 – maximum file size savings, but comparatively slow compression speed.īrotli vs GZIP Benchmarks: Which Performs Better?.In total, it has eleven different levels that follow a similar pattern as GZIP: Like GZIP, Brotli also has different compression levels. While it took some time for adoption, Brotli is now supported by all major web browsers in 2019. It was initially released in 2013 by software engineers from Google, though it didn’t focus on HTTP compression until 2015. BrotliĬompared to GZIP, Brotli is much younger. Level 9 – maximum file size savings, but comparatively slow compression speed.Īll major browsers support GZIP and most web hosts also support GZIP out of the box.Level 1 – small file savings, but very fast compression speed.In total, GZIP has nine quality levels that balance compression level vs speed: GZIP is based on the DEFLATE algorithm and, while people usually just refer to it as a single compression tool, there are actually different “levels” of GZIP compression. It still retains that position today – according to W3Techs, 78.6% of websites use GZIP compression at some level. Since the ’90s, GZIP has been the dominant format for web compression. GZIP’s initial release was all the way back in 1992. The difference, of course, is in how they go about compressing your site and how effective they are.īefore we compare performance benchmarks, though, let’s cover the basics of GZIP and Brotli. So at a high-level, both Brotli and GZIP are quite similar with respect to their core purpose. Brotli vs GZIP Compression: What’s the Difference?īoth Brotli and GZIP are methods to compress your website’s files. In addition to comparing both methods, we’ll also show you how to use both Brotli and GZIP compression on your WordPress site. So when it comes to Brotli vs GZIP compression for your WordPress website, which one should you be using? More importantly, does that question actually matter, or is either compression method fine? Let’s find out! But it’s not the only compression game in town – Brotli is a newer, Google-backed compression method that was released in 2013 and is quickly picking up steam. Compressing your WordPress site’s files is a great way to shrink your page sizes, speed up your site and improve your Core Web Vitals performance.įor a long time (since the 90s), GZIP compression has been the gold standard for web compression.
