Does using CDN files increase website speed?

Hi all. My website is very slow. Speed 16. I am now editing the images to be smaller, but someone told me that instead of uploading them while in the customization theme, I should make paths from CDN files as this will make my website faster.

Is this true?

I tried this on my slide but I ended up with an image I cannot customize. Please see the printscreen. Any advice is welcomed.

If you’re uploading images into your theme they are already on CDN’s and will be loaded directly from your website, so you’re all good there.

Making images smaller will help, but also make sure you’re compressing images. Here’s a guide with a couple ways to do that: https://speedboostr.com/how-to-compress-images-on-shopify.

To see what images can be compressed, along with any other optimizations you should perform, run your site through the Shopify Analyzer. That’s a free tool my team (Shopify optimization experts) built for the community.
