JPG to WebP FAQ
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox, Safari and Opera have all supported WebP for years, on desktop and mobile. Only very old browsers such as Internet Explorer do not.
What quality setting matches my JPG?
A WebP at 75–85% is generally indistinguishable from a JPG saved at 85–90%. Because the source is already a JPG, going much higher only increases size without adding detail.
Will converting improve image quality?
No. The WebP is made from the JPG's pixels, so it cannot be better than the source. The benefit is a smaller file.
Can WebP files be opened in image editors?
Current versions of Photoshop, GIMP, Affinity Photo, Paint.NET and the default viewers on Windows and macOS all open WebP.
Why did one of my files get bigger?
A JPG that was already compressed very heavily can come out larger at a high WebP quality. Lower the quality setting for those files.
Why WebP makes pages faster
Images are usually the largest part of a web page. WebP uses prediction techniques borrowed from video compression: each block of the picture is predicted from its neighbours and only the difference is stored. This makes it more efficient than JPG, a format designed in the early 1990s, particularly for smooth gradients and at medium quality levels.
Smaller images mean less data to download, which shortens load time and improves metrics such as Largest Contentful Paint that search engines use to assess page experience. If you need to support very old browsers, serve WebP with a JPG fallback using the HTML picture element.
When adopting WebP on a website, convert the original high-quality images rather than images that have already been compressed several times, and compare a few results side by side at the size they will be displayed. A quality of around 75 to 85 usually matches a JPG at 85 to 90 while saving a quarter to a third of the size. Remember to update image references in the HTML or CMS and to keep descriptive alt text and explicit width and height attributes, which help both accessibility and layout stability.
