The need to Optimize Images
The web page includes images whose presence is one of the main factors that affect load time, especially in websites that contain a lot of images such as photographer websites. As an example, a blog site that had 100 images each approximately 2MB in size would need to download 200MB of image data, which assuming average user internet bandwidth of 18-19MB/s would take an average user around 4-5 seconds to download, before any other content is loaded. A single page with 12 pictures working out to be approximately 1.5MB each could make a load time one second longer, and twice as many pictures would make that wait one second longer as well. This explains the reason why pages that include image galleries take longer to load. In sum, photographer SEO professionals suggest that, to optimize load times and search engine rankings, image files should never exceed 500kbs though preferably should be much lower at 300kbs. Improving Core Web Vitals is important to achieving faster loading times, and this is extremely vital to sites such as WordPress blogs.
Major steps to optimize images
1. Pre-Upload Optimization
Images should also be optimized before adding it in your media library both in terms of quality and file size.
This preemptive early action could really go far towards influencing the performance of your website.
2. Pick the correct Image Format
The choice of the image format is one of the significant essentials of image optimization. Although no universally in stone rule exists, common advice goes that JPG should be used to store photography, PNG to images with plain colors or gradients and logos and graphs, and scalar images with plain colors or gradients should go into SVG. In the case of animations, one may use CSS animations instead of animated GIFs which may become heavy. The next-gen image formats such as WebP may also be served to speed up page load.
3. Reduce the Size of your Photos
It is important because image compression is important when one wants to decrease the size of a file without a major compromise in quality. This may include such features as the use of tools such as Photoshop save for web but other lossless compression methods need to be explored. Compressing JPEGs entails whether small compression artifacts are acceptable and whether the color profile on every picture needs to be added. It can also help to save files and make them RGB not CMYK and having the optimized JPG turned on.
4. Reduce the size of your pictures.
Another important step is to resize the images to the size they are required. One should evaluate whether it is necessary to fit the entire size or whether a smaller dimension can be expanded, even covered by some kind of decor or smear. Another thing you need to think about is whether or not that image necessarily has to be high-res. When using various types of screen devices, it is worthy to come up with adequate media queries to make sure that the size of the images is suitable to each device.
5. Responsive and Lazy Loading
Letting the images naturally appear by implementing a lazy loading will streamline images only when they are about to appear as compared to when the page has loaded.
This is capable of drastically reducing opening page load times. Speed of loading is further enhanced by responsive image techniques, which deliver different sizes of the images depending on the device of the user and the sizes of the screen.
Final Optimization.
Optimizing images should envisage more than a basic compression. Begin by asking yourself whether you really need an image file, whether you could accomplish the same appearance using a background color or a CSS gradient to more efficiently accomplish the same visual effect. When it comes to photographers, it is fine to have larger image files but again moderation is the word of the day; the more pages have images the greater the need to trim down on the size of each image file to ensure a decent load time. On some platforms such as Showit images used on pages are automatically optimized but with blogs we have to do it manually before uploading. There is always more progress that an optimization tool will propose, however, the plateau of the valuations frequently varies on the faithfulness between quality and file size.
