Best Free Tool to Convert PNG to WebP and Instantly Boost Website Speed (No Login, No Limits)
Let’s be honest — slow websites kill conversions, rankings, and reputation.
And one of the biggest reasons your site is underperforming? Heavy PNG images that haven’t been optimized.
The solution is simple, fast, and completely free: Convert your PNGs to WebP using pngtowebp.org.
⏱️ Why Website Speed Matters (A Lot)
Here’s what happens when your site takes too long to load:
- 📉 Your bounce rate skyrockets

And most of the time, it’s not your server — it’s your images.
🎯 Why WebP Is Better Than PNG

| Feature | PNG | WebP |
|---|---|---|
| File Size | Large | 🔽 Up to 40% smaller |
| Transparency | ✅ | ✅ |
