Why convert JPG to WebP?
WebP is an image format created by Google for the web. At the same visual quality, a WebP file is typically 25–35% smaller than a JPG and up to 80% smaller than a PNG — and it supports both transparency and animation. Smaller images mean faster pages, better Core Web Vitals (LCP) and a higher score in Google PageSpeed Insights.
Every modern browser supports WebP: Chrome, Edge, Firefox, Safari (since iOS 14 / macOS Big Sur), Opera and Samsung Internet. WordPress, Shopify, Wix and most CMSs accept WebP uploads too.
Sometimes you need the opposite: a WebP image downloaded from a website that will not open in an older app, or cannot be uploaded to a form. Select JPG or PNG above to convert WebP to JPG for maximum compatibility — animated WebP files can be turned into a GIF.
WebP vs JPG vs PNG vs GIF vs AVIF
| Format | Typical size | Transparency | Animation | Best for |
|---|---|---|---|---|
| WebP | −25–35% vs JPG | Yes | Yes | Websites, online shops, blogs |
| JPG | Reference | No | No | Photos, email, printing, universal sharing |
| PNG | +200–500% vs JPG | Yes | APNG | Logos, screenshots, graphics |
| GIF | Large | 1-bit | Yes | Simple animations, old platforms |
| AVIF | −40–50% vs JPG | Yes | Yes | Modern websites, HDR photos |
Serve WebP with a JPG fallback
To be safe with very old browsers and email clients, publish both files and let the browser pick. Open any converted image and use Copy HTML to get this snippet with the right size filled in:

<source srcset="photo.webp" type="image/webp">
<img src="photo.jpg" alt="…" width="1200" height="800" loading="lazy">
</picture>Pro tips
- A quality of 75–82 is visually indistinguishable from the original for most photos — try the before/after slider at 200% zoom.
- Use Lossless for logos, icons, screenshots and PNG graphics with sharp edges or text; lossy WebP is better for photos.
- Converting an already compressed JPG to WebP cannot restore lost detail, but it still saves space. Start from the highest-quality original you have.
- Resize to the size your website actually displays (for example 1920 px wide) — that often saves more than the format change itself.
