How to automate the resizing and cropping of product photos for 5 different e-commerce marketplaces at once?

Automation & No-Code, Design & Visuals

This task shows how to plan a batch image workflow that outputs correctly formatted images for five marketplaces. You will define target sizes and crop rules, then apply them in a safe, repeatable process.\n\nSet up validations to ensure every image meets minimum quality and category requirements before publishing.

Who is this for?

- E-commerce product teams\n- Freelance photographers\n- Marketing teams with multiple marketplaces\n- Ops teams handling catalog updates\n- Agencies managing product media

Before you start

- Source image collection ready\n- Target size/crop specs defined for each marketplace\n- Basic image quality standards documented

General Process (How it works)

  1. Capture requirements Collect target sizes and crop rules for each marketplace.
  2. Prepare source dataset Gather a representative set of product images for testing.
  3. Define output targets List width, height, aspect ratio, and file format per marketplace.
  4. Create batch processing plan Outline a single script that applies all rules in sequence.
  5. Implement image processing Implement resizing and cropping with a tool or code.
  6. Validate outputs Check image dimensions, formats, and cropping accuracy; fix failures.
  7. Automate and error-handle Wrap steps in a pipeline, add logging and retry logic.
  8. Documentation Document steps, parameters, and usage to reuse.
  9. Publish and monitor Release as a reusable task and monitor results.
