Drop WebP files above, download JPGs. The format that opens in everything: old editors, office documents, marketplace forms, systems that predate WebP.
The usual source: an image saved from a website. Sites serve WebP for speed; your browser saves what it was served. Converting to JPG makes it usable everywhere else.
JPG or PNG as the target?
- JPG for photos. Smaller, universally accepted. This page.
- PNG when transparency must survive or the image will be edited repeatedly. JPG flattens transparency onto white. WebP to PNG is linked below.
Quality: website WebP files were usually compressed once already and converting re-encodes it again. The default therefore stays conservative at 90%, where the second pass is invisible. Avoid round-tripping formats repeatedly. Convert once, keep the result.
Size expectation: the JPG often comes out larger than the WebP, because WebP is simply the better compressor, and what the extra bytes buy is a file that opens everywhere.
Wrong file dropped? The page names the file and says it cannot open that type.
A WebP that was already lossy has given up detail once, and saving it as JPG gives up a little more, which is worth knowing if the picture is heading into an editor afterwards.
Batches work per file, with the before and after bytes shown and a ZIP for the lot.
