Optimize images and improve SEO

Applies to: All Krown themes. Last checked: 2026-10-13.

Large images slow your store down, and images without alt text tell search engines little. Shopify and Krown themes already handle part of this; an app such as Tiny SEO Speed Image Optimizer helps with the rest.

Where to find it: image alt text in Shopify admin → Products (each product's images) and Shopify admin → Content → Files

What Shopify and the theme already do for your imagesCopy Anchor Link

• Shopify's image server sends each image in WebP or AVIF to browsers that support them, without any action from you.
• Krown themes ask Shopify for several image sizes, so a phone downloads a smaller file than a large desktop screen.
• Krown themes load images further down the page only when the customer scrolls near them (lazy loading).

So you do not need an app for lazy loading or image formats. What still helps: compressing very large uploads, writing alt text, and giving image files meaningful names.

Do I need an app to add image alt text?Copy Anchor Link

No. You can write alt text yourself: open a product in Shopify admin, select an image and fill in its alt text. Other images have their alt text in Content → Files. An app saves time when you have many products.
