How to Convert PNG to WebP for Shopify and Speed Up Your Store Instantly

Is your Shopify store slow to load? Are you losing customers because of long image load times?

Large PNG images are one of the biggest performance killers on Shopify. The fix? Convert PNG to WebP — the modern, lightweight image format preferred by Google and all modern browsers.

In this guide, you’ll learn how to use pngtowebp.org to easily convert your images and dramatically improve store performance — no apps, no coding, and no extra cost.

🛒 Why Shopify Store Speed Matters

In eCommerce, speed = sales.

• 📉 1-second delay in load time can reduce conversions by up to 20%
• 🚀 Faster stores rank higher in Google
• 📱 Mobile users bounce quickly if images load slow
• 💰 Fast sites build trust and increase purchases

Image optimization is the fastest way to speed things up — and converting PNG to WebP is a powerful, free upgrade.

📷 Why WebP Is Better Than PNG

• ✅ 25–40% smaller file sizes than PNG
• ✅ Supports transparency (just like PNG)
• ✅ Maintains visual quality
• ✅ Loads faster across mobile and desktop
• ✅ Helps you pass “Serve images in next-gen formats” in PageSpeed Insights

Shopify doesn’t automatically convert your images to WebP — you need to do it yourself or use a tool.

💡 Expert Tip: Use WebP + Lazy Load

If you're comfortable editing your Shopify theme code, you can combine WebP images with lazy loading to get maximum speed. You can also add a <picture> tag for fallback PNGs (for rare unsupported browsers).

<picture>
  <source srcset="image.webp" type="image/webp">
  <img src="image.png" alt="product image">
</picture>

🎯 Final Thoughts: Every KB Counts in Shopify
