​If your site takes approximately 2-3 seconds to load, you have a FAST WEBSITE.

For your information, a normal site can take 5 to load and still get no problem. You n find more information here : https://www.hobo-web.co.uk/your-website-design-should-load-in-4-seconds/

Now, If your website really takes a longer time for loading, let's look at the diagnosis:

There are many factors affecting the speed of a website, such as javascript, 3rd party app, lazyload, and image size. Please know that image compression will play a part in increasing site speed, but it isn't the only deciding factor.

We can assure you that Smart Image Optimizer greatly reduces the total image weight on the total page weight. According to Speedboost statistic, page weight is a key factor in load speed. Try to keep your pages under 4MB max. 2MB and under 2MB is a good goal to shoot for.

However, there is one issue related to images that the app hasn’t been able to solve yet - OVERSIZED IMAGES. Oversizing means that the dimension of the images (height and width) exceeds the standard size recommended by Shopify. (2048 x 2048 for square images, ideal for display product images). You can manually resize your images with Photoshop, Paint or a free online tool like this https://picresize.com/

There are many successful cases of stores that increase website speed by using the image compression solution by Smart Image Optimizer app. So please ensure that all the other factors that slow down your website are completely solved before optimizing images for the best result.

A quick checklist to make the most of our app:

• Choose the right compression type: Lossy 85% recommended.

• Compress all image types: product, collection, asset, blog featured images.

• Custom Upload features to optimize banners, homepage images, about us page image, images within the product description...

• Check how much the image size saved after optimization.

There are several cases that used our app but doesn’t have good results on the speed:

• Too many issues that negatively affecting site speed: javascript, webfont, CSS, lazyload... (In that case, our app alone can’t boost the whole site).

• Not fully optimize all images or Not select the right compression type.

• The image size is already lightweight. For example, your original image is 140KB, optimizing it will get it down to 80KB. But you won’t be able to notice big changes.

However, many stores have successfully implemented the app. Hear their feedback in the review:
