Here are a few tips to help you optimize your customizer's speed if you feel that it does not load and run as quickly as you would like it to.
Reducing your canvas and image sizes
Smaller dimensions mean lighter weight and faster loading times.
Reduce your customizer canvas size, the maximum recommended size is 1200 x 1200 pixels.
Resize and save your product images to match your new canvas size with Photoshop.
Reducing your thumbnail image sizes
Make sure your thumbnail images are not too big (minimally 50px x 50px but no larger than 300px x 400px).
Compressing your png images
Compress your PNG images using TinyPNG.
Re-upload your compressed images in Kickflip's product builder.
Use a Shopify product template
If your customizer feels slow to load, Shopify product templates can help improve performance. By keeping your customizable product pages as lightweight as possible — especially by limiting the number of apps and scripts running on the page — you create a faster, smoother experience.
Is it taking a long time before the Kickflip loading icon appears?
In some cases, longer loading times are not related to the Kickflip app. The problem could be happening on your ecommerce store, before the Kickflip Iframe is loaded. This article explains how to find the cause of a slowness on your site using Google Chrome.
