For web design and web development, image size matters much. Image with web-quality is a great way to fill the need for smaller sized images for websites. You’ll find an image that directly comes from a DSLR, but it’ll issue on your website to load and crawl. Besides, an image with over-compressed can speed up your site after get rightly optimized by the website development services.
However, the quality of the image will get a slap. So, image optimization is very vital in this issue. There are two considerable things of an image that you need to deal with. Those are photos as well as icons or illustrations where the techniques of checking image quality are a great way to work well in most cases.
Now, let’s know some essential things regarding image optimization in advanced web development services.
Web Designer Toolbox
You’ll find there three types of image file that you can use while creating a website like .jpg, .png, and .svg. Among the types, jpg is the best to use when you have images for landscapes, scenery, and people. You need to use for 20kb to 70kb images for images in content like an image for the blog article. Also, you can use images with up to 500kb, but it’s good to stay up to 2000kb.
JPG is somehow a lossy image type as it degrades and recompresses the image quality when you export. Also, they don’t handle gradients nicely. Due to having an image with gradient, you can separate it into two parts. So, it’s easy to render the issue of a gradient in some other backgrounds if you use CSS gradients.
Besides, PNG format is ideal for icons and logo designing as they’re transparent. Another reason is that the icon and logo use a very limited color palette. But, SVG is best in these three formats and most designers use it for vector art as it’s scalable. Although this format is the best for logos, it works for rendering the browser to overcome the issue of page loads.
Optimization Techniques
You should optimize the images you’re going to use for your website to get the different benefits. There are three ways to optimize images like ImageOptim, ImageAlpha, and Scour. They respectively work for JPGs and PNGs, for PNGs, and for SVG format.
Optimizing JPGs
While using ImageOptim, you can reduce the file size of your JPGs and PNGs images. You can use 1600x1200px dimension for bigger images for background panels. When you have finalized the image resolution after resizing, you get its output in Photoshop for the high-quality. If you compress the image and found it loses its fidelity, you should use this tool for better output.
Retina JPGs
If you want to target retina or some other higher displays, it’ll work best to save in JPG format with double resolution. But, when you’ll use a higher compression rate like 50 to 60, it also provides you good looking high-quality retina image.
Also, the image will be as standard as lower-density. This is a well-appreciated technique that allows you to use a particular asset for standard and retina displays.
