How to Optimise Images for Web Design?
Website design is a very detailed and creative process that involves many components such as images, videos, and content that should be informative, aesthetic, and technically sound. Whether you have a business website, an online store, or even a blogging site, it pays to optimise every image you upload on your website. Optimising images for the website mainly involves three things- making images look good, optimising loading time, and making images easy for search engines to index. If you are a beginner in web development and want to know more about image optimisation for the web, then read this guide.
#1 Choose the correct file type: JPEG or PNG
If you are wondering which image file type to use, remember that your website will work better with a JPEG or PNG format.
JPEG- This file type can compress all the colours in a photograph in a relatively small file size. With JPEG’s you won’t end up with a large file size that you may get if you save a file in PNG format.
PNG- Graphics that contain large flat areas of colours should be saved as a PNG file. Designs, infographics, logos, etc., should be uploaded in PNG file format.
#2 Resize images to optimise page speed and appearance
While using images during web development, you have to find the right balance between image size and resolution. Higher resolution will occupy a larger file size. Using a large file size will increase the file size of your website, slowing down its loading speed. You need to compress large images into smaller file sizes not exceeding more than 200kb. Many images resizing software and tools will get you optimum image quality within a compact file size.
#3 Make images the same size and style
A good website design practice is to use images of a consistent style and size. Consistency will come in handy when lining up your text, columns, and other information on the website. When the photos are all of the same sizes and oriented in a similar fashion, it makes web pages look aesthetic and organised.
#4 Use keywords to name the image file for better SEO
Website design teams often don’t think much about the file names of images. It is usually a part of SEO. But as a standard practice, web designers must take a moment before naming an image that is to be uploaded on the website. This is because images should be optimised through keywords for better search engine optimisation at a later stage. Also, naming image files makes them easier to manage in the backend.
#5 Fill out captions and Alt texts
Filling out additional information about the images on your website gives some added juice to your SEO efforts. Alt texts are important as it gives the search engine a basic idea about the image. Alt text should be a keyword phrase that describes what the image is showing. Alt text also gives information about the image when it fails to load on a user’s browser.
