Shopify product image size and requirements

2048 x 2048 pixels, square, for every product photo.

That is Shopify's own recommendation for square images, it clears the 800 x 800 zoom threshold with room to spare, and it gives modern high density screens enough pixels when a theme renders the image at 1024 points wide.

The important word is every. Consistency matters more than the exact number. A store that standardises on 1600 x 1600 throughout looks better than one that mixes 2048 squares with 3000 x 2000 landscapes, however good the individual photos are.

If your products are genuinely different shapes, such as a mix of rings and rugs, keep the canvas square and let the padding around each product vary. That way the grid stays even.

Resize before you compress, and compress once.

• Resize to 2048 pixels on the long edge. Most of the weight in a camera or phone file is pixels you are never going to display.
• Export JPEG at 80 to 85 percent quality. For a product on a plain background that usually lands between 150 KB and 400 KB.
• Strip metadata. Camera profiles and embedded previews add weight and display nothing.
• Do not re-save a JPEG repeatedly. Each save discards more detail, and it compounds.

Use PNG only when you actually need transparency, such as a logo or a product that has to sit on a coloured section. A photographic PNG is often five times the size of the equivalent JPEG for no visible gain.

Upload at more than 800 x 800 pixels and then test it on a real product page.

Zoom failing is quiet: the image simply does not magnify, and there is no warning anywhere in the admin. If you have imported a catalogue from another platform or from a supplier feed, it is worth checking a sample, because supplier images are often 600 x 600 or smaller.

Where the source images are too small, upscaling with a model that reconstructs detail is more useful than a plain resize, which only makes a soft image bigger. Photomop is a photo studio that runs on your own device and its upscale tool is aimed at exactly this, though a genuinely low quality supplier photo will still look like a low quality supplier photo.

Shoot to the strictest rule you will ever need, then relax it per channel if you want.

• No promotional text or badges burned into the product image. Google Merchant Center disapproves items for this and Meta's catalogue rules are similar.
• Keep a clean version of every product photo alongside any styled version, so the feed can point at the clean one.
• Square, at least 1000 pixels covers the minimum for the major feeds comfortably.
• Fill the frame. A product lost in whitespace looks worse in a Shopping result than it does in your theme, because the surrounding context is gone.

Pick the target ratio first, then work through in batches rather than product by product.

Decide on square at 2048, then process each collection as a batch: resize the long edge, pad to square on a consistent background, and export at a consistent quality. Doing it collection by collection means the grid looks right as you go, rather than being uniformly wrong until the last product is done.

Batch processing is the only sane approach past about thirty products, and it is worth resisting the temptation to hand tune individual images. Consistency is the thing you are buying.
