WebP is the image format recommended by Google PageSpeed Insights because it stores the same photo in fewer bytes than JPG, typically 25–35% less at a similar visual quality. Converting your JPGs to WebP makes pages load faster, saves bandwidth and helps your Largest Contentful Paint score.
Add a batch of JPG or JPEG files, choose the quality, and download the WebP versions individually or in a ZIP ready to upload to your site. Encoding is done by your browser, so your photos remain on your computer.

Using WebP images on your website
All current versions of Chrome, Edge, Firefox, Safari and Opera display WebP, so for most sites you can simply replace the JPG with the WebP. If you must support very old browsers, use the HTML <picture> element with a WebP <source> and the JPG as the fallback <img>.
WordPress, Shopify and most modern CMSs accept WebP uploads. Remember to resize photos to the size they are actually shown at before converting; a 4000-pixel photo in WebP is still far heavier than it needs to be. The Resize Image tool can do that first.
When to keep JPG instead
Keep JPG for files you email, print or upload to forms and marketplaces that do not list WebP as accepted. Some desktop apps and older phones still cannot open WebP files.
Frequently asked questions
How much smaller will my images be?
It depends on the photo and the quality you choose, but WebP files are typically 25–35% smaller than JPGs of similar quality. The list shows the exact saving for each file.
Does WebP work in Safari and on iPhone?
Yes. Safari has supported WebP since version 14 (2020), on both macOS and iOS.
Will converting JPG to WebP lose quality?
WebP is lossy at these settings, so there is a slight generational loss. At quality 80–90 it is very hard to see, while the file gets clearly smaller.
Is it safe to convert client photos here?
