PLATFORM REFERENCES

Check the platform rule before choosing a preset.

Upload support, image dimensions and storefront presentation are not the same thing. These references separate documented platform facts from independent preparation advice and link to the original help pages.

Question	Etsy	Shopify
Where to verify	Current listing-image and Search Visibility help pages.	Current product-media documentation and your store theme.
What can change the result	Upload conditions, thumbnail editor and the listing surface.	Theme crop, collection-card ratio and responsive layout.
Final check	Inspect the saved draft and its actual thumbnail preview.	Inspect the uploaded product in the live theme on phone and desktop.

This comparison is a navigation aid, not a complete list of platform rules. Follow the linked official documentation for the current details.
