Best image format for web scaling code#

These images are often 2-3x smaller than the legacy formats we know and love (jpg, png). Happily, there's some pretty low-hanging fruit! In this tutorial, we'll see how we can leverage 'next-gen' image formats like WebP. Many developers (myself included!) tend not to think about media size much at all. So the raw number of bits over the wire is super important right now!ДЄnd sites typically have way more than 200kb worth of images it's not uncommon for a page to have several megabytes of images. Our devices can still parse and compile javascript at the same speed they could a couple weeks back, but network speeds have gotten slower. This shifts the calculation a little bit. Fortunately, because Site Reliability Engineers are both brilliant and tireless, most of the internet is still up and running, but there's definitely something going on-I have a 100mbps connection, but it feels more like 3G at the moment. With a pandemic sweeping across the globe, I've found that my internet has gotten pretty choppy. This is still very true, but it's a little less significant at this exact moment in history.

Just be aware that these costs are not quite equivalent. A JavaScript bundle needs to be downloaded and then parsed, compiled, executed -and there are a number of other steps that an engine needs to complete. Even if your website is only displaying them at a smaller size, the URL for the original images can often be reverse-engineered from the source code, and your images can get stolen. From the article:ДЄ JPEG image needs to be decoded, rasterized, and painted on the screen. But first, regardless of file formats (JPG, PNG, GIF, TIF, etc.), you should never upload high-resolution images to your site just for display purposes. For this reason, we recommend making use. The three options weвЂ™re going to introduce below are some of the most popular and useful formats, which makes them perfect picks for almost any website. It can be tempting to serve high-resolution images to all users when catering for displays of varying pixel density.

In The Cost of JavaScript, Addy makes a really good point: 200kb of JavaScript is more 'expensive' than 200kb of images, because the browser needs to do more work to use code compared to images. The 3 primary image formats used on the web: JPEG vs PNG vs GIF As we mentioned earlier, there are some image formats that are used much more commonly online than others.
