If you run a word press site audit through pagespeed insights, you can recommend that lighthouse encode images efficiently. Pagespeed insights (PSI) is a tool for generating performance reports for the entire word press page. If it is detected that the image can be better optimized, the \
Jump in! What does it mean to encode images efficiently? Encoding images efficiently means optimizing images and reducing file size without affecting quality. How does lighthouse display images as optimized? What is the cause of this problem? Lighthouse scans all images on the page being audited and sets the compression level to 85%. If the potential savings exceed 4KB, report the image and mark it as an error in the performance report. The potential saving effect is better than 4B (24.6kb), so lighthouse shows the image. High quality uncompressed images tend to increase the file size. The larger the image, the longer it takes to and render it to visitors. If this happens to all images, the total load time may increase and the website may slow down.
To avoid this, we share six optimization techniques that can appropriately provide images on the web. WordPress provides six methods to efficiently encode images: including the following six steps, which can be used to efficiently encode images and process this pagespeed insight suggestion: Let’s take a look at each step of image compression delay loading to convert images to webp (next generation format) and provide images of the correct size. CDN uses animated GIF to convert images to video. 1. Image compression the goal of image compression is to reduce image files without damaging too much quality. Pagespeed insights is very satisfied because it can store and render images in the most efficient format and encode them appropriately. There may be loss in image compression, but there is no loss if you don’t want to affect the image quality.
However, if the correct tool is used, the lossless compression is not visible to the naked eye. In the following example, one is a source file and the other is a compressed file. Can you see the difference? I can’t make it. The image of the driveway has a great impact on the page speed and will reduce the speed of the WordPress website. The easiest way to avoid performance problems is to use the word press plug-in. never mind. We have done a lot of work for you and compiled a list of image compression plug-ins that are most suitable for WordPress. This also applies if you prefer to compress images manually. If Photoshop and lighthroom are burdensome, there are many alternative optimization tools available.
2. Delayed loading implementation delayed loading is an optimization technology. Its goal is to display images only when needed, so it helps to encode images efficiently. If the user is viewing the image, render the image in the browser. Otherwise, the load is delayed to specify the priority of the most important content. Google recommends that pagespeed \

If you don’t want to manually delay loading the content you can see without scrolling, please use the free WordPress plug-in such as lazy load by WP rocket, or check the best delayed loading plug-in of WordPress. 3. Convert the image to webp (new generation format), which is a new generation image format developed by us to provide better lossless and loss compression for the image. As a result, WordPress sites can better encode images and pass pagespeed audits. In fact, Google says, \
Small file size webp – source: greeninspector are you sure? The imageify plug-in can convert images to webp directly from the WordPress dashboard. To learn more about this new generation format, we recommend that you read how word press uses webp format. 4. Provide lighthouse with images with correct size, and you can easily find images with incorrect size on WordPress site. If you audit the page and find the \
You can also use the devtools elements panel to view the display size of the image. Identify my image size on the Elements tab – source: devtools this part sounds easy, but given the various screen sizes available in 2022, the situation can quickly become complex. One rule: ideally, a page cannot provide an image larger than the user’s screen. The average desktop screen size is 1920 x 1080 pixels. Most mobile phones have a device width of 400 pixels. For WordPress sites, images can be uploaded to the page through the media library or directly. Google recommends using the best image size (including reaction breakpoints). The core is to adjust the size appropriately without using the full-size image.
Keep the image file size less than 200 KB. For most images, a maximum width of 800 pixels is sufficient. If you keep the image between these numbers, it will be quickly loaded on your device. In sketch, you can further optimize the image based on each device, as follows: Male Apple device size – source: there are many options to adjust the size of sketch software image appropriately to prevent the website from slowing down.
