Step-by-Step Guide
4 steps · takes under 1 minute
Resize to 2048×2048px square
Shopify recommends square product images at 2048×2048px. Use the Resize tool to hit this dimension. Crop to square first if needed.
Convert to WebP
Shopify now supports WebP natively. WebP is 25–35% smaller than equivalent JPG — significant for pages with many product images.
Compress to under 1MB per image
Target under 1MB per product image. Most 2048×2048px WebP files at 85% quality are 200–600KB.
Upload and verify in Shopify
Upload to your Shopify product listing. Use Google PageSpeed Insights to confirm your product page loads in under 3 seconds.
100% Private — Zero Uploads
ImgToolkit runs entirely in your browser using the Canvas API. Your images are never sent to a server, never stored in the cloud, and never seen by anyone else. This makes it safe for sensitive documents, client work, medical imagery, and confidential screenshots.
Pro tip
Pre-optimizing images before uploading to a platform gives you more control than relying on the platform's automatic (and often aggressive) compression.
