In this blog post, we’ll explore the causes of this issue and provide step-by-step solutions to ensure your product images remain crisp and clear.

Understanding the Blurry Image Problem

Why Do Images Become Blurry?

When upgrading to a Shopify 2.0 theme, store owners might notice that their previously sharp product images suddenly appear blurry. This issue can occur due to various reasons:

1. Theme-specific image rendering settings
2. Conflicts between old and new theme code
3. Changes in image processing algorithms

Impact on User Experience

Blurry images can have a significant negative impact on your store:

1. Reduced product appeal
2. Lower customer trust
3. Potential decrease in conversion rates

Identifying the Problem

To determine if you’re facing this issue:

1. Check multiple product pages
2. Compare image quality before and after the upgrade

Before diving into more complex solutions, start with these basic checks:

3. Modify the image size parameter (e.g., change ‘300x’ to ‘master’)

Different image formats suit different needs:
