Introduction

Mobile internet is huge and it brings back old “friends” like flaky latency and slow downloads. A faster site is a greater joy, so time for us to improve and add both Brotli and WebP support to our hosting platform..

codar is web performance, always looking for ways to improve your website speedindex. In this blog I’ll describe our experience with Webp and Brotli, both web techniques that create smaller files for a faster website. (and a better SEO score!)


What is WebP?

WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.

WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.

Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. For cases when lossy RGB compression is acceptable, lossy WebP also supports transparency, typically providing 3× smaller file sizes compared to PNG.

What is Brotli?

Brotli is a modern open-source compression algorithm developed by Google to help further reduce the size of files. It is used as a server technique to transparently compress files for the visitor to allow smaller, and thus quicker, transfers.

Here are a few of the highlights that make Brotli a leader in compression:

  • Brotli is independent of CPU type, operating system, file system, and character set.
  • It can produce a compression ratio that is comparable to the best compression methods currently available and most importantly is considerably better than Gzip.
  • It decompresses much faster than current LZMA implementation.

Supported by all modern browsers enabled by default

Brotli and WebP will make your website faster and increase your Google speedindex score!

Recently we transparently enabled both WebP and Brotli support on our hosting platform. The results have been great, at least 20% smaller files on average and a big improvement on our Google Insight score!

Speed-as-a-Service

But the best thing is that you don’t need to do anything when hosting on our platform! We updated our systems to transparently encode all applicable images to the smaller and more efficient WebP format while retaining your original images. Our webservers will serve WebP to modern browsers while preserving original images for incompatible browsers. This works for all websites and webshops, no plugins needed! (note: you can always enable and disable this feature.)

So sit back, relax and enjoy technology!
