So even those few extra seconds can be critical in engaging visitors as well as boosting overall sales.
Having a fast website is crucial. More than just boosting your rank in Google, it also drives in more conversions and boosts overall sales. Whether you sourced your photos from stock photography websites or you decided to DIY your product photos, optimizing images is very important to make sure that your website performs with speed.
Basically, image optimization is the process of compressing image files to reduce their existing file size, and yet maintain the image’s overall quality as much as possible.
You may wonder if the final result looks too different from the original image, why is there still a need to optimize? While compelling, high-quality images are a huge factor in drawing in visitors to your site, there is a downside to it. Images have big file sizes, which can significantly affect your site’s overall performance. After all, a slow-loading site will have higher bounce rates ‒ meaning people will leave your site even before they get to interact with it.
Here are four ways to reduce website loading speed through image optimization:
JPEG is the best format to create a lighter image. It compresses the image and you can choose the quality degree.
If you want an image to have a more transparent background, then you need to use a PNG file format. Although it creates higher quality images, it doesn’t compress images as a JPEG does and usually has heavier files. PNGs are used in smaller amounts and are for smaller images.
GIF is usually used for animated images.
If you want to know the best file format, usually, in most cases, JPEG will always be the better choice. If you need an image with a more transparent background, a PNG format will be a better fit.
Images can play a vital role on your website, and a high-quality photograph that is professionally-taken is an advantage. There are a lot of product photography guides on the internet so it’s not a big deal to have one for your website.
Almost 96% of the internet’s entire image traffic is from GIF, PNG, and JPEG formats. Note that if you’re using third-party tools will make the end product of your image much larger.
Since GIF and PNG are lossless formats, during the compression process, there will be no visual modification on the images. If you’re using still images, PNG does an excellent job with the compression ratio as well as the overall image quality. On the other hand, if you’re working with animated images, to achieve a better compression, a video element is preferred over a GIF.
