Convert WebP to JPG, free and on your device

What WebP is, and why you might need a JPG

WebP is an image format Google introduced in 2010. Websites use it because it makes smaller files than JPG or PNG for the same picture, which is why images saved from a web page so often arrive as .webp.

Not everything accepts it. Older photo editors, some office software, many upload forms, print services and messaging tools still expect JPG or PNG. JPG is the format that works almost everywhere.

How to convert WebP to JPG

1. Choose your WebP images, or drop them on the box. You can add up to 30 at once.
2. If an image has transparent areas, pick the colour to fill them with. White is the default.
3. Set the quality. 90% keeps the loss very hard to see.
4. Press Convert, check the preview, and download. Each JPG keeps the original name, so photo.webp becomes photo.jpg.

Transparency: JPG has none

A WebP can have transparent areas, like a logo with no box around it. JPG cannot store transparency at all, so every transparent pixel has to become a solid colour. The page uses white unless you choose another colour, and the preview shows exactly the image you will download, background included.

If you need to keep the transparency, JPG is the wrong format; PNG keeps it. This page only makes JPGs.

Animated WebP

A WebP can also be an animation. A JPG holds one still picture, so the animation cannot survive the conversion, and the page never quietly keeps one frame and drops the rest. When you add an animated file it tells you how many frames it has and asks what you want: the first frame as one JPG, or every frame as its own JPG.

Saving every frame needs a browser feature that is not available everywhere yet. Where it is missing, the page offers the first frame only and says why. Files with more than 100 frames can only be saved as their first frame, because anything more would mean hundreds of separate downloads.

Quality, size and metadata

JPG is lossy: saving as JPG always discards some detail, and converting a lossy WebP to JPG compresses the picture a second time. At the default 90% the difference is very hard to see. Lower settings make smaller files with more visible artefacts around edges and in smooth areas.

Do not expect a smaller file. WebP usually compresses better than JPG, so the JPG is often larger. The page shows the original size and the JPG size so you can see for yourself.

The width and height stay exactly as they were. The only exception is an image too large for the browser to build, which on iPhone and iPad means over about 16.7 megapixels; the page asks before converting such an image at a reduced size.

Metadata is not copied. EXIF, XMP and any colour profile in the WebP are left out of the JPG, and the page tells you when the original carried any of them.

What happens to your images

They stay on your device. Your browser already knows how to read WebP, so the image is decoded and re-encoded right there. Nothing is uploaded to CMeIn or anyone else, which you can confirm in your browser's network panel.

Nothing is added to a gallery, whether or not you are signed in to CMeIn. If you have accepted analytics cookies, we count anonymous events such as a conversion finishing or failing, with no image, no file name and nothing about you attached.

Tips

• Converting a JPG to WebP and back cannot bring back detail that was lost. If you have the original JPG, use that.
• For logos, icons and screenshots with sharp edges, a high quality setting avoids the fuzzy halos JPG can leave around text.
• If an image only looks wrong because of its transparent areas, try a background colour that matches where you will use it.
