Shopify product photo requirements & best image size (2026)

Shopify is forgiving on technical specs but unforgiving on visual consistency. The platform accepts a wide range of formats and resolutions, but conversion rate is driven by image consistency across SKUs, mobile-first sizing, and matching the storefront aesthetic. This page is the quick reference plus a few production tips most theme docs skip.

Shopify image requirements (2026)

Recommended dimensions	2048 × 2048 px (square) — Shopify recommends this for zoom and Retina displays
Maximum dimensions	5760 × 5760 px (the hard cap; bigger uploads get rejected)
Maximum file size	20 MB per image
Accepted formats	JPG, PNG, WebP, GIF, HEIC (auto-converted server-side to WebP/AVIF)
Aspect ratio	Square (1:1) is the safest; Shopify themes crop non-square images to fit grid cells
Background	Any — but white or transparent is standard for product page primaries
Color profile	sRGB (Shopify converts on upload but starting in sRGB avoids color shifts)

Best practices that move conversion

→Use a consistent background across every SKU on a collection page — visual noise on a grid kills conversion
→Upload at 2048×2048 minimum even if your theme renders smaller; Shopify generates srcset variants automatically and zoom needs the raw pixels
→First photo = primary (storefront thumbnail). Make it the cleanest cutout or white-background shot you have
→Photos 2-5 = lifestyle / context. This is where conversion lives on mobile because they swipe past the primary fast
→Alt text matters for SEO and accessibility — write what's in the photo, not your keyword stack

How Palmou AI lines up with Shopify's specs

Generate listing-ready images in seconds. Here's how each part of the output maps to Shopify's requirements.

Native source resolution

The cutout flow preserves your source's native resolution — a 4K phone photo gives a 4K transparent PNG, easily above Shopify's 2048 recommendation.

WebP output

All scene-gen output is WebP quality 92 — Shopify accepts it natively without re-encoding.

Consistent backgrounds

Pick one scene (e.g., White Studio) and apply it to your whole catalog for grid consistency. 1 credit per image, predictable cost.

Square aspect ratio

Scene-gen output is square (1:1) by default — exactly what Shopify themes expect.

FAQ — Shopify images

Does Shopify accept WebP product images?▾

Yes. Shopify accepts WebP uploads directly and serves WebP/AVIF to compatible browsers via its CDN. Palmou AI outputs WebP quality 92 by default.

What's the best image size for Shopify in 2026?▾

2048 × 2048 px is the sweet spot — high enough for Retina zoom, low enough that your CDN bills stay reasonable. Shopify's max is 5760 × 5760 but that's overkill for product photography.

Will Palmou AI output work with my Shopify theme?▾

Yes. WebP square images at 1024px+ work with every modern Shopify theme (Dawn, Sense, Trade, and the popular paid themes). For higher resolution on the primary image, use the cutout-only flow which preserves source resolution.
