Shopify Image Too Large: How to Fix Megapixel and Byte Upload Errors

Direct Answer: Shopify rejects product images if they exceed 20 Megapixels (20 million pixels) or 20 Megabytes (20 MB). The error "Image exceeds 20 megapixels" commonly occurs when uploading raw smartphone photos (e.g. iPhone 48 MP ProRAW captures or high-resolution mirrorless DSLR files). Even if the file was compressed to 1.5 MB, Shopify will refuse the upload if the dimensions exceed $Width \times Height > 20,000,000$.

The Official Shopify Recommended Image Settings

According to official Shopify documentation:

• Optimal Dimensions: 2048 × 2048 pixels (1:1 square). This provides sharp high-DPI clarity for customer zoom-in inspection while loading rapidly on mobile.
• Maximum Resolution: 4472 × 4472 pixels (or any dimension multiplying to $\le 20\text{ MP}$).
• Recommended Formats: WebP or JPG.
