Google optimize images how to#

If you have a responsive website, and are wondering how to load the correct size of an image across different devices, then you should consider implementing the srcset and sizes attributes of the img tag instead of the plain src tag. To resize image to 400 width and 200 height, you can use tr=w-400,h-200 400x200 image To get a 200px wide image, use tr=w-200 query parameter 200px wide image

A real-time solution allows you to quickly adapt your images to changes in layouts.įor example, the original image is 1280×853px.

You do not have to do this resizing manually or write any code of your own to do it.

It is best to use a real-time image resizing solution like ImageKit for this, which allows you to resize and crop image to any dimension using URL parameters. So, you must resize and crop your original image, which measured about 5000×3000px to the above three sizes. Suppose, you probably need this image on three different pages on your website, each with a different size requirement. Once the image has been converted to the right format, it is also important to bring it down to the right dimensions that are actually required on the page.Īn image clicked using a DSLR camera could be more than 5000×3000 pixels, which is not what you need on your website. Learn more about how ImageKit can serve images in AVIF format on the same image URL, without you needing to change anything in the backend.Īdditionally, ImageKit also takes into account other factors like image content type, compression level, etc., to deliver the best format that returns the smallest possible image size. It supports conversion to next-gen image formats like AVIF and WebP. You can use ImageKit to deliver the images in the right format automatically. Google’s PageSpeed tool also does not report cases where JPEG2000 and JPEG XR are not used. With such low adoption numbers, you can skip doing these entirely to save some effort. JPEG2000 is supported in Safari, whereas JPEG XR is supported in IE browsers. However, both JPEG2000 and JPEG XR have not really caught up with browser support at 13% and 4%, respectively. With Firefox also adopting it, it is now supported in over 80% of devices. Higher compression while maintaining the visual quality means your images consume lesser data over the network and are downloaded faster.Īmongst these formats, WebP is the one that has seen the maximum adoption. WebP, AVIF, JPEG2000, and JPEG XR are modern image formats supported in the browser providing better compression and visual quality as compared to the older JPG and PNG formats. Let’s have a look at them and how you can solve each using different techniques. So, it’s usually the first and easiest thing to provide a solution for.ĭownload cheat sheet What are the issues with images reported by Google?Īs of the date this article was published, Google PageSpeed Insights reports 5 issues with images on the website. And you can solve these problems, that too, without any extensive changes from your end in your code. Image optimization is now available as a standard from a lot of tools like ImageKit. Most often, images are the lowest hanging fruit in your goal towards overall page performance improvement. And now, with the use of Lighthouse, it gives some stellar suggestions for improving the image-related assets on your website.

And since images are a part of the page, those get included in the report as well. Google PageSpeed generates a report for the entire page.

Does this PageSpeed also give reports for images? This is done by taking into account many different reports and analyses using Google Lighthouse, details of which can be found here. PageSpeed Insights analyzes the content of a web page and then generates suggestions to make that page faster. It is a free-to-use tool by Google that gives you a lot of insight and performance suggestions for improving the page load time. And Google knows it.Īnd if that wasn't enough, as per Google, there's a direct relation between conversion rates and page load time. And they don't have the time or tolerance for a website that doesn't respect that. They're an impatient bunch with a very short attention span. Page speed affects load time and meddles with user experience, something Google gives a lot of weight to and has even mentioned.įor a user, there's absolutely nothing as annoying as a slow website. While no one knows what all the factors go in determining Google ranking, it is a well-known fact that page speed is one of the primary ones. Thus, it is critical for anyone pursuing business seriously to rank well on Google. Google is a major source of traffic for most businesses.
