WebP Images: How to Convert To and From WebP Format
Everything you need to know about WebP — what it is, why it makes pages faster, and how to convert JPG, PNG to WebP and back.
WebP is the web's most efficient image format — and it is now supported by every major browser. Switching from JPG and PNG to WebP is the single most impactful change most websites can make to improve page speed scores. Here is everything you need to know.
What Is WebP?
- WebP was developed by Google and released in 2010. It uses both lossy and lossless compression techniques, supports transparency (like PNG), and supports animation (like GIF). The result is files that are:
- 25–34% smaller than equivalent JPG files
- 26% smaller than equivalent lossless PNG files
- Fully supported by Chrome, Firefox, Safari, Edge, and Opera
Why WebP Makes Your Site Faster
Page speed directly affects SEO rankings. Google's Core Web Vitals — specifically Largest Contentful Paint (LCP) — is heavily influenced by image load time. Switching a 500KB hero JPG to a 350KB WebP file saves 150KB on every page load. Across a full website, this adds up to significantly faster pages and better search rankings.
How to Convert JPG to WebP
1. Open the JPG to WebP converter 2. Select your JPG files 3. Convert runs in your browser — no upload 4. Download as WebP For PNG files, use the PNG to WebP converter instead.
How to Convert WebP Back to JPG
Some older software and email clients still do not handle WebP. To convert back: 1. Open the WebP to JPG converter 2. Select your .webp files 3. Download as JPG This is completely lossless for the conversion step (though the original lossy compression from when the WebP was created cannot be reversed).
WebP vs JPG vs PNG: Quick Comparison
| Format | Transparency | Animation | File Size | Compatibility |
|---|---|---|---|---|
| JPG | No | No | Medium | Universal |
| PNG | Yes | No | Large | Universal |
| WebP | Yes | Yes | Small | Modern browsers |
| AVIF | Yes | Yes | Very small | Partial |
Should You Use WebP for Everything?
For web use — yes. For anything that needs to be opened in desktop software, printed, or sent as an email attachment — stick with JPG or PNG. The rule: WebP for web delivery, JPG for everything else.
Can I Compress WebP Files Further?
