How to convert JPG to WebP
- Choose your JPG photos or drop them on the page.
- Set the quality – 75–85 % is a good range for websites – and, optionally, a maximum width such as 1920 px.
- Download the WebP files one by one, or all together as a ZIP.
How much smaller is WebP?
In Google's comparison, lossy WebP images are 25–34 % smaller than JPGs of the same visual quality. Resizing often saves even more: a 4000-pixel camera photo shown 1200 pixels wide wastes most of its bytes. Good starting points:
| Image | Max. width | Quality |
|---|---|---|
| Full-width hero image | 1920–2560 px | 80 % |
| Image in an article | 1200 px | 80 % |
| Thumbnail or product tile | 400–600 px | 75 % |
Use about twice the displayed width if the image should look sharp on high-resolution screens.
Browser support and when to keep JPG
All current browsers display WebP – Chrome, Edge, Firefox and Safari 14 and later – so no JPG fallback is needed on most websites. Keep JPG for email newsletters, print services and anyone who will open the files in older programs. Creating WebP needs a browser that can write the format: Chrome, Edge and Firefox can; if yours cannot, this page tells you.
Frequently asked questions
Which quality should I use for WebP?
75–85 % for websites gives small files with no visible difference for most photos. Use 90 % or more for images with fine detail or text.
Do all browsers support WebP?
Yes, all current ones. Safari has supported WebP since version 14 (macOS Big Sur and iOS 14).
Is the EXIF data kept?
No. The photo is turned the right way up, but metadata such as camera details and GPS location is not copied – which also keeps files smaller and protects your privacy.
Are my images uploaded?
No. The conversion runs in your browser, and your images never leave your device.
