Convert WebP to JPG

The number one source of WebP files on ordinary computers is the save-image menu. Sites serve WebP to browsers because it is lighter, so what lands in your downloads folder inherits the format whether you wanted it or not. Browsers open it fine; the trouble starts one step later, when the file meets software with a longer memory - an older Photoshop or Office install, a photo kiosk at a pharmacy, an embroidery or laser-cutting program, a government portal whose validator was written when WebP did not exist. JPEG is the one raster format that predates them all, which is why converting to it makes the problem vanish.

Mechanically, the conversion decodes the WebP into raw pixels and hands them to a JPEG encoder. If the source was lossy WebP - most are - you are stacking one lossy step on another, so quality choice matters more here than when converting from a lossless format. The default of 90 keeps the second-generation loss invisible in practice; drop lower only if you also need the file small, and avoid re-converting the same image repeatedly.

Two properties of the source can disappear on the way through, and it is better to know beforehand. Transparency is one: JPEG has no alpha channel, so any see-through region gets flattened onto a background colour you choose here. Animation is the other: an animated WebP contains many frames, and a JPG can hold exactly one, so this tool exports the first frame and tells you it did, rather than failing silently.

None of this requires size trade-offs to be scary. A JPG from a typical saved-from-web WebP is modestly larger than the source - often 20-40% - which is the price of universal compatibility and rarely matters for a file destined for a document, a print order or an upload field.
