Generate on-brand, high-resolution product images tailored for your Shopify store. Consistent styling, perfect backgrounds, and theme-ready photos — no photographer needed.
5 free images every month. No credit card required.
Your Shopify store theme dictates specific image aspect ratios and presentation styles. Whether you use a minimalist theme with white backgrounds or a lifestyle-forward layout, Katalyst AI generates images that slot straight into your collection and product templates. Consistent product photography across your collection pages creates a premium shopping experience that increases average order value and reduces bounce rates.
Shopify recommends square images at 2048x2048px for optimal display across devices, with a maximum file size of 20MB. Katalyst outputs images at the ideal resolution and automatically optimises them for fast page load times. Faster-loading product pages improve your store's SEO ranking and reduce the abandoned cart rate from impatient mobile shoppers.
Shopify merchants adding new products weekly need a scalable photography solution. Traditional product photography costs between fifty and three hundred pounds per product, making it prohibitive for growing stores. Katalyst lets you generate unlimited product image variations from a single phone photo, so you can launch new products and test new collections without photography bottlenecks.
The best Shopify merchants constantly test their product pages. With Katalyst, you can generate multiple image styles — white background, lifestyle, in-context — and A/B test which version drives the highest conversion rate. Data-driven image selection can improve your product page conversion rate by ten to thirty percent.
Every image and listing Katalyst generates respects Shopify's current rules, dimensions, and content policies. Spec version 2026-04.

Compliance notes
Shopify has no central image policy. Merchants set their own rules. The spec here reflects modern best practice.

Every image Katalyst generates targets Shopify's current image spec: 2048 x 2048 px minimum, WEBP, PNG formats, and the product fill and background rules Shopify enforces. Spec version 2026-04 is pinned in our compliance database and updated whenever Shopify changes its guidelines.
Our compliance database is versioned per marketplace. When Shopify updates dimensions, formats, or content policy, we update the spec centrally and every image generated after that uses the new rules. You do not have to rebuild your listings manually.
Katalyst respects Shopify's 80-character title limit and 8000-character description limit when it generates listing copy. Compliance warnings surface before you publish so you never hit a rejection after upload.
No. The generator, the listing copy engine, and the export step all read from the same Shopify spec, so the output is ready to paste into Seller Central, the bulk uploader, or your catalogue sync without manual tweaks.
