How to add & optimise product images on Shopify

Great Shopify product images are square, high-resolution, on a clean background, and consistent across the catalogue. Here's how to get them right — and how to stop doing it by hand.

Shopify product image specs

• Shape: square (1:1) is the safe default — it lines up in collection grids.
• Size: Shopify supports up to 4472×4472 px (20 MP). Around 2048×2048 px is the practical sweet spot for zoom + fast loading.
• Format: Shopify serves WebP automatically; upload high-quality JPG or PNG (PNG for transparency).
• Background: clean white or transparent for a consistent catalogue look.
• Alt text: describe the product — good for accessibility and SEO.

Adding images to a Shopify product

1. Prepare a square, high-res image on a clean background (~2048 px).
2. Upload under Media on the product, or push via the Admin API for automation.
3. Add descriptive alt text.
4. Reorder so the best shot is first — it becomes the featured image.

The problem with doing it manually

For a handful of products this is fine. For a growing catalogue it isn't: shooting, editing out backgrounds, exporting, naming files, finding the right product and uploading — for every SKU, every time stock changes — is slow and drifts out of consistency.

Automate it with the Shelfshoot Shopify app

The Shelfshoot Shopify app installs in two clicks and removes the manual steps entirely. Scan a product's SKU, shoot it with any phone, and Shelfshoot removes the background, crops to a consistent square and publishes the finished image straight onto the matching Shopify product — no folders, file names or uploads. You're billed per image through Shopify Billing, so there's no separate subscription.
