Speed Up Your WordPress Site by Converting PNG to WebP (No Plugin Required)

If your WordPress website is loading slowly, large PNG images might be the culprit — especially if you're using Elementor, WPBakery, WooCommerce, or any image-heavy theme.

The fastest way to boost your site's speed and performance? Convert those PNGs to WebP format.

With pngtowebp.org, you can do it without installing any plugins or writing a single line of code.

🚀 Why PNG Images Slow Down WordPress

PNG is great for quality and transparency, but it's a heavyweight format. On WordPress sites, PNGs often cause:

• ❌ Poor PageSpeed Insights scores
• 📉 High LCP (Largest Contentful Paint)
• 🐌 Slow mobile loading
• ⚠️ SEO penalties from Google

If you've seen “Serve images in next-gen formats” in Lighthouse or PageSpeed — this is why.

✅ Why Convert PNG to WebP for WordPress

• ⚡ WebP files are 30–40% smaller than PNGs
• ✅ WebP supports transparency (just like PNG)
• 📱 Loads faster across mobile and desktop
• 📊 Improves your Core Web Vitals (LCP, CLS)
• 📈 Helps you rank higher in search engines

Most WordPress image optimization plugins don’t let you control exactly what gets converted. pngtowebp.org gives you full control — instantly.

🛠️ How to Convert PNG to WebP for WordPress (The Easy Way)

1. Go to pngtowebp.org
2. Upload one or more PNG images from your media library or local system
3. Click “Convert”
4. Download the WebP version of each image
5. Upload them to your WordPress Media Library
6. Replace PNG image links with the new WebP ones in Elementor, Gutenberg, or Classic Editor

No need to bloat your site with yet another plugin.

🧠 Pro Tip: Use <picture> Tags for Compatibility

To support all browsers (even older ones), use a <picture> tag:

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

This tells modern browsers to use WebP — and fall back to PNG for legacy ones.

💡 Where to Replace PNG with WebP in WordPress

• 🖼️ Hero images and headers
• 🛍️ WooCommerce product images
• 📰 Blog post featured images
• 🎨 Icons, logos, infographics
• 📋 Background images and banners

Every kilobyte saved improves your load time.

📈 Real Results: PageSpeed Before vs. After

Before: PNG hero image — 850KB, LCP score: 3.6s After: Same image in WebP — 520KB, LCP score: 2.1s

This single change improved load time, SEO score, and mobile performance — all without plugins.

🎯 Final Word: Simple Speed Wins

Most WordPress users overlook image formats — but that’s exactly where speed gains are hiding.

pngtowebp.org gives you a free, powerful way to convert PNG to WebP — instantly, and without the need to install or configure anything.
