SIZES

Shopify image sizes

Square product images should be 2048 × 2048 px. Shopify accepts anything up to 5000 × 5000 px and 20 MB — but the number that actually costs you money is file weight, not dimensions.

Every dimension, in one table

2048 px square is the figure to remember for products. It is what Shopify itself recommends, and it is the smallest size at which the zoom-on-hover behaviour still looks sharp on a high-density screen. Going bigger does not make it sharper; it only makes the page heavier.

The hard limits

• Maximum 5000 × 5000 px, or 25 megapixels.
• Maximum 20 MB per file. You should never come close.
• Formats accepted: PNG, JPEG, WebP, GIF, SVG, HEIC, PSD, TIFF, BMP — including animated GIF and WebP.

The limits are generous enough that almost nobody hits them. The constraint that actually bites is speed.

The number that matters more than dimensions

Aim for around 300 KB per product image. Shopify's own guidance puts a general page image at roughly 500 KB and warns that anything approaching 20 MB will visibly damage load times.

A 2048 × 2048 PNG straight out of an editor can easily be 4–6 MB. The same image as an 80%-quality JPEG or WebP is usually 200–400 KB and indistinguishable to a shopper. WebP is the better default if your workflow supports it.

This is not a pedantic point. Product pages are where the money is, and image weight is usually the largest single thing slowing them down.

Consistency beats precision

One thing matters more than hitting any exact number: every main product image should share the same aspect ratio.

Mixed ratios are what produce the ragged collection grids you see on unfinished stores — one product tall, the next wide, the row heights fighting each other. Shopify will pad or crop to fit, and neither result is what you intended.

What breaks when you get it wrong

• Too small — zoom looks soft, and on a retina display the whole image looks slightly out of focus.
• Too heavy — slow product pages, worse Core Web Vitals, and a measurable drop in conversion on mobile.
• Mixed ratios — uneven collection grids and unpredictable cropping.
• Transparent PNG where you wanted white — transparency renders as whatever the theme's background is, which is not always white.

A workable default

If you want one rule rather than a table: 2048 × 2048, JPEG or WebP at around 80% quality, under 400 KB, same ratio on every product. That is correct for the overwhelming majority of stores, and it is the setting to use unless you have a specific reason not to.

Generating images at these sizes

Worth stating plainly, since it is the reason this page exists: LAZY60 generates listing images from a single product photo, and its 2K output is 2048 px — exactly Shopify's recommended product image size. Aspect ratio is selectable per image, so a set can be produced at a consistent 1:1 for products and 16:9 or 3:1 for banners without resizing anything afterwards.
