How to Convert PNG to WebP Online Free (Smaller Files, Same Quality)
Convert PNG images to WebP format for up to 80% smaller file sizes. Free online converter — no signup, works on any device.
Why Convert PNG to WebP?
PNG is excellent for quality but produces large files. WebP is a modern image format developed by Google that achieves:
- 50–80% smaller file sizes than PNG at the same visual quality
- Transparency support — unlike JPG, WebP preserves transparent backgrounds
- Universal browser support — Chrome, Firefox, Safari, Edge and all modern mobile browsers
If your PNG images are used on a website, converting to WebP is one of the easiest ways to speed up your pages.

PNG vs WebP vs JPG: Which to Use?
| Format | Transparency | File size | Best for |
|---|---|---|---|
| PNG | Yes | Large | Logos, graphics, screenshots |
| JPG | No | Medium | Photos, hero images |
| WebP | Yes | Small | Everything — especially web |
For web images, WebP is the clear winner. It is smaller than both PNG and JPG while supporting transparency.
Does WebP Work Everywhere?
Yes — for web use. All modern browsers have supported WebP since 2020 including Safari on iPhone. The only exception is very old browsers (IE11) and some older image editors.
For documents and print, PNG or JPG are safer choices since not all software supports WebP yet.
How to Use WebP on Your Website
If you are using WordPress, the WebP Express or Smush plugins convert and serve WebP automatically. For custom sites, the HTML picture element lets you serve WebP with a JPG fallback:
```html
<picture>
<source srcset="image.webp" type="image/webp">
<img src="image.jpg" alt="Description">
</picture>
```
