WebP files from Chrome, Android, and websites can't be opened everywhere. Here's how to convert them — and when to convert to WebP for better performance.
You right-clicked an image on a website to save it — and your computer saved a .webp file instead of a .jpg. Now nothing can open it. Or you're a web developer trying to switch your site to WebP for better performance. Either way, this guide covers everything about WebP conversion.
WebP has become the default format for images on modern websites. When Chrome downloads or saves an image, it saves it in the format the server served — which is increasingly WebP. Other common sources of WebP files:
Converting WebP to JPG is the most common reason people need a WebP converter. JPG works everywhere — in Photoshop, on older Windows systems, in email attachments, and on every platform on earth.
How to convert WebP to JPG with PNGtoJPG:
The entire process takes under 10 seconds. All conversion happens in your browser — no file upload, complete privacy.

If you're a web developer or website owner, converting existing JPG images to WebP is one of the easiest ways to improve page speed. WebP files are typically 25-35% smaller than JPG at equivalent visual quality.
Google's PageSpeed Insights often recommends "Serve images in next-gen formats" — WebP is what they mean. Converting your site's images to WebP can significantly improve your Core Web Vitals scores and Google ranking.
Batch convert JPG to WebP:
WebP supports alpha transparency — just like PNG. Converting transparent PNG files to WebP typically saves 30-50% on file size with zero quality difference. For website logos, icons, and UI graphics with transparency, PNG to WebP is a significant optimization.

PNGtoJPG supports batch conversion for all WebP-related conversions. Instead of converting files one by one, select up to 50 files simultaneously:
Windows 10 and 11 can open WebP files in Microsoft Edge and Chrome natively. However, Windows Photo Viewer (the default photo viewer in older Windows versions) cannot open WebP files. Solutions:
Most email clients — including Outlook — do not display WebP images inline. If you're attaching images to emails, convert WebP to JPG first. JPG attachment emails display correctly in all email clients worldwide.
When converting to WebP, quality settings work similarly to JPG:
| Quality | Use Case | File Size vs JPG |
|---|---|---|
| 90-100% | Archiving, print prep | Similar to JPG |
| 80-90% | High quality web images | ~20% smaller |
| 70-80% | Standard web images (sweet spot) | ~30% smaller |
| 60-70% | Thumbnails and previews | ~40% smaller |
