Theme speed and consistent squares still win on mobile storefronts. Resize a whole export to Shopify-friendly dimensions, compress in one pass, and ZIP back out before you touch Admin.
Use the step-by-step Shopify catalog workflow (upload → resize → compress → checks → ZIP) so merchandising and studio teams share the same order of operations.
Preset and guide: Shopify image resizer — then open Bulk Resize and pick Shopify Product (2048×2048) before compressing.
If bytes—not pixels—are the blocker, run Bulk Compress after resize. Compare batch vs one-file tools: batch vs one-file compressors.
