A catalogue in one pass
Shop photos arrive in every shape. One rule pads them all to the same square on white and names them by product, and the plan lists every file before the run so a mis-filed photo shows up in the wrong folder before it is written.
Questions about shopify image resizer
What does Shopify accept?
Shopify's help centre says uploads must not exceed 20 megapixels or 20 MB, and recommends JPEG for product photos and PNG for transparency. It was read on 2026-10-18.
Why pad instead of crop?
A product cut off at the edge looks like a mistake in a grid. Padding keeps the whole product and makes every tile the same square.
How do I get a folder per product?
Drop a folder with one sub-folder per product. The name template starts with {parent}, so each product's photos land in a folder of the same name.
What about Amazon, Flipkart or Etsy?
They are not shipped as named presets until their seller documentation is checked. The Marketplace square preset (2000 × 2000, white) is there with the note to check your seller dashboard.
