The right-click-save problem
WebP is the format you get, not the format you chose. Developed by Google for faster page loads, it is served automatically by most large websites. Every modern browser displays it, so the format is invisible until the moment you try to use the saved file somewhere else: an old desktop app, a corporate system, a print shop, an upload form. That is the moment this page fixes. Because browsers decode WebP natively, this particular conversion loads no extra engine at all; it is instant even on a phone.
Quality expectations for re-encoded web images
Images saved from websites were usually compressed twice before they reached you: once by the creator and once by the site's CDN. Converting to JPG at the default 90% adds a third, mild pass. In practice the result is indistinguishable at normal viewing sizes. If the image contains a lot of text, for example a saved infographic, choose WebP to PNG instead: lossless output sidesteps compounding artifacts entirely.
Common questions
Why did that image save as WebP in the first place?+−
Websites serve WebP because it is about 30% smaller than JPG, and when you right-click and save, you get the file as served. Google Images, Instagram, Reddit and most modern sites do this. Your browser displays it fine; the problem starts when older software or an upload form refuses it.
Which programs still reject WebP?+−
Older Photoshop versions (before 23.2), Microsoft Office image insertion in some builds, many government and job-application upload forms, and a long tail of older viewers and printers. JPG is accepted by effectively everything made since the 1990s.
Will converting lose quality?+−
Marginally. Most WebP files on the web are already lossy, and re-encoding to JPG at 90% adds a second, visually negligible compression pass. Only images with sharp text or line art may show slight softening; use 95% quality for those, or convert to PNG for exactness.
Does this handle animated WebP?+−
The first frame is converted, since JPG is a still-image format. Full animated WebP to GIF conversion is a separate tool on our roadmap.
