How to convert JPG to WebP
- Drop your JPG photos into the box.
- WebP is already selected. Quality 80–90 is a good choice for websites.
- Download the WebP files one by one or as a .zip.
Why use WebP on a website?
Images are usually the heaviest part of a web page. WebP files are typically 25–35% smaller than JPGs of the same visual quality, so pages load faster, use less mobile data and score better in Google PageSpeed Insights, which literally suggests "serve images in next-gen formats". Every current browser — Chrome, Safari, Firefox and Edge — supports WebP.
Does WebP work in WordPress, Shopify and Wix?
Yes. WordPress accepts WebP uploads since version 5.8, and Shopify, Squarespace and Wix accept them too. Some email clients and older desktop programs still cannot open WebP, so for email attachments JPG remains the safer choice.
Quality and size tips
- Resize first. A 4000-pixel photo shown 1200 pixels wide wastes most of its bytes. Use Resize Image before converting.
- Quality 80 is the sweet spot for most photos on the web; go to 90 for product photos where detail matters.
- Converting a JPG never adds detail, so start from the best original you have.
Private by design
The WebP encoder built into your browser does the work. Your images never leave your device.
Frequently asked questions
How much smaller is WebP than JPG?
Usually 25 to 35 percent smaller at the same visual quality, sometimes more for large photos.
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox and Safari (since iOS 14 and macOS Big Sur) all display WebP.
Can I convert PNG to WebP here too?
Yes. PNG, AVIF, GIF and BMP files are accepted as well; see also the PNG to WebP page.
Will my JPG lose quality?
WebP is lossy like JPG, so the image is re-compressed. At quality 85 to 90 the difference is not visible.
Are my images uploaded?
No. Everything runs in your browser on your own device.
