PNG vs WebP: Which Is Better for Websites in 2025? (And How to Convert for Free)
Images play a huge role in how fast your website loads — and how well it ranks. In 2025, choosing the right image format is no longer optional.
The most common question we hear is: “Should I use PNG or WebP for my website?”
In this article, we’ll break down the differences between PNG and WebP, and show you how to convert PNG to WebP for free using pngtowebp.org.
📷 What Is PNG?
PNG (Portable Network Graphics) is a popular image format that supports lossless compression and full transparency. It’s great for:
- ✅ Logos and UI elements
- ✅ Images that require sharp edges and transparency
- ✅ Lossless quality (no blur)
But the downside? PNG files are huge. Especially with large images, they can significantly slow down your website.
🖼️ What Is WebP?
WebP is a modern image format developed by Google. It provides the same features as PNG — including transparency — but with drastically smaller file sizes.
- 🔥 25–35% smaller than PNG (on average)
- 💨 Faster loading time = better SEO
- 📱 Perfect for mobile-first performance
WebP supports both lossy and lossless compression, plus alpha transparency. That makes it ideal for almost all use cases where you would traditionally use PNG.
