The loading speed of you website is one of its key features. Even if your site has a great look, content, and functionality you might still be losing visitors. If you want to provide a positive experience to your audience, you need to look for ways to optimize the load time. Amazon reported a 1% rise in revenues for every 100 milliseconds increase of their site speed.
Images will help you to make your site look better and add value to it. Besides, with meaningful images with the contents, you will be able to connect better with the visitors. But on the other hand, images take a lot of bandwidths and that increases the loading time of your website. Here are few tips for the images of your website to optimize the loading time.
- Mentioning image dimensions will let you cover other non-replaceable elements. You should specify the height and width tags in <img> elements.
- Scale your images properly and scale them down before uploading to the website. If you upload the full image and later scale them down with CSS, it will ultimately make the browser load them in full size and will not optimize time.
- Some images have extra colors and added comments. You need to remove the extra comments and reduce the color depth as much possible. You can also take help of different editor and optimization tools.
- For the images in your website, the best option is to use JPEG formats. If you are using PNG format, make sure your browser supports the format.
- Do not use BMP or TIFF formats for your site.
- If you want to add GIF, use smaller and simpler graphics of less than 10*10 pixels.
