If you have WordPress site, compressing images is ridiculously easy thanks to a handy-dandy ShortPixel plug-in that is directly installed into your WordPress dashboard — just set it and forget it and it will automatically optimize your images!
While ShortPixel is patiently waiting for Shopify to approve the app ShortPixel created, you can use the “unofficial” ShortPixel app in the meantime by simply typing in your URL.
For some of you (hint: agencies), the best part of ShortPixel may be the sub-account feature.
With this feature, you can create sub-accounts for clients, allot X amount of pictures and gifs per month for them, and then charge them!
