Shopify productimage size.

The sizes, file types and limits Shopify’s help centre gives for product photos, and how to bring a catalogue of small ones up to standard.

Updated 10 November 2026

Pick one aspect ratio and keep it.

Collection pages put product images next to each other. When featured images come in different shapes, they show at different sizes, so Shopify advises using the same aspect ratio for every featured image. Square is the easy choice.

Themes can crop for you as well. Open an image under Content, then Files, and set a focal point: the part of the photo a theme should keep when it crops.

Switching ratio later means re-cropping every featured image in the store. Settle it before your first big upload.

File names Shopify trips over.

Shopify’s file rules hide one naming quirk that catches stores out:

  • A file name must not start with a full stop.
  • Avoid ending a name with pico, icon, thumb, testing, small, compact, medium, large or grande.
  • The Shopify CDN reads those endings as resize requests, so a file like test_medium.png gets a suffix added.
  • Letters, numbers, spaces and symbols are fine.

What Shopify does after you upload.

  • Serves the right format

    Shopify’s Imagery service checks which formats a shopper’s browser supports and shows the best one.

  • Keeps your original

    In Content, Files, the download button saves the original, unoptimised file.

  • Works with any theme

    Every theme supports product images, though each one lays them out its own way.

Bring small photos up to size in bulk.

Supplier photos of 500 or 600 px look soft against a 2,048 px target. Sizzle Photo runs inside the Shopify admin and fixes them in batches. Each clean-up removes the background and upscales 4×, so a 512 px image comes back at 2,048 px.

  1. Open Sizzle in Shopify

    It sits in your admin next to your other apps.

  2. Select the small photos

    A few products, a collection or the whole catalogue.

  3. Choose white or transparent

    The 4× upscale comes with it. 2 credits a photo, charged to your Shopify bill.

  4. Compare and save

    Check before and after. Your originals stay until you replace them.

Shopify image size, briefly.

What is the best image size for Shopify products?

For square photos, 2,048 × 2,048 px. Shopify says that size usually looks best.

What is the maximum image size on Shopify?

5,000 × 5,000 px or 25 megapixels, in a file smaller than 20 MB.

Why are my Shopify product images different sizes?

Your featured images probably have different aspect ratios. Give them all the same ratio and the collection grid lines up.

Should I upload PNG or JPEG to Shopify?

Shopify calls PNG the best file type for most product images, with JPEG second. It then serves each browser the best format it can show.

Does Shopify resize product images automatically?

Yes. Every upload is saved in several sizes for product pages, collection grids and other parts of the theme.
