Convert WebP to JPG

Where all these WebP files came from

WebP is Google's image format, and over the last few years it has quietly taken over the web. Sites adopted it because it produces substantially smaller files than JPG or PNG at the same quality, which makes pages load faster and costs less bandwidth to serve.

Every current browser displays WebP perfectly. That is precisely why you did not notice the change — until you right-clicked, chose "Save image as", and ended up with a file your desktop software treats as a stranger.

Support outside browsers is still patchy. Older Photoshop versions need a plugin. Microsoft Word and PowerPoint have been inconsistent about it. Many print shops, photo labs, marketplace listing forms and internal business systems reject it. So converting back to JPG remains a routine chore.

The honest trade-off

This conversion costs you something, and you should know what.

WebP is a lossy format, like JPG. Converting between two lossy formats means decoding one approximation and creating a second approximation of it. Detail already discarded by the WebP encoder stays gone, and the JPG pass discards a little more on top.

In practice, at quality 85 — the default on this page — the second pass is not visible at normal viewing sizes. But this is a one-way trip in quality terms, so keep the WebP original if you might need it later.

The file will also get bigger. WebP is simply more efficient. On our test photograph, WebP at quality 80 was 121 KB where JPG at the same setting was 337 KB — nearly three times larger for the same picture. Expect a similar jump. See our full WebP vs JPG vs PNG comparison for how that gap holds up across other kinds of images.

Two WebP quirks that surprise people

Transparency

Unlike JPG, WebP supports an alpha channel, and plenty of WebP images taken from websites — logos, icons, product cutouts — use it. JPG cannot. Transparent areas are filled with white during conversion here rather than the black you get from a naive canvas export.

If the transparency matters, JPG is the wrong destination. Convert to PNG instead, which preserves it exactly.

Animated WebP

WebP can hold animation, functioning as a modern replacement for animated GIF. JPG holds exactly one frame. If you convert an animated WebP here you will get a still image of the first frame and the animation will be lost — there is no way around that within the JPG format. Nothing will warn you at the point of conversion, so check the result if you suspect the source was animated.

Metadata

WebP files can carry an Exif chunk, though images served from websites usually have had it stripped during optimisation. CloudlessConvert does not currently copy Exif metadata from a WebP source into the resulting JPG — the metadata-preservation toggle applies to JPG and HEIC sources. For most images saved from the web there is nothing left to preserve anyway, which is a privacy feature of how the web publishes images rather than a limitation here.
