Convert WebP to PNG

Turn a WebP from a website into a PNG that keeps its transparent background.

Convert to

Processed on your device. Files are not uploaded.

Right-click, “Save image as…”, and the file ends in .webp. Many sites serve WebP because it loads quickly. Browsers and current phones open it, but older editors, some upload forms and a fair number of desktop apps still expect PNG or JPG.

Does the transparent background survive?

Yes. PNG has the same kind of alpha channel as WebP, so transparent and half-transparent pixels stay that way: a logo cut out on a website stays cut out. This is the main reason to pick PNG over JPG for a WebP. A JPG has no transparency, and the converter would fill those areas with white.

How much bigger will the PNG be?

Much bigger, if the WebP is a photo. A 38.0 KB WebP of a coffee cup (600×400) came out as a 480 KB PNG, about 12 times larger. A 1000×872 picture of the Hubble Deep Field went from 135 KB to 1.9 MB. Both WebPs were saved with lossy compression, and PNG has to store the result pixel for pixel, grain and all.

For photos, that size buys you nothing. The same coffee cup through WebP to JPG was 48.3 KB. Pick PNG for logos, icons, screenshots and anything with sharp text or transparency, where PNG stays small and JPG would blur the edges.

What happens to an animated WebP?

You get a PNG of the first frame. The converter does not create animated PNGs.

Anything else that does not carry over?

EXIF details such as the camera or date, if the WebP had them. If it carried a rotation flag, the rotation is applied to the pixels and the PNG comes out upright.

Need a transparent background that the WebP never had? That is a job for Remove background.

Questions and answers

Will the PNG look worse than the WebP?

No. PNG is lossless, so it shows exactly the pixels decoded from the WebP. If the WebP was saved with lossy compression, that loss is already in the picture and stays there; the PNG adds none of its own.

Is the color profile kept?

Yes, when the WebP has one: it is copied into the PNG. Most WebP files from websites have none and are plain sRGB, which is what viewers assume anyway.

Can I convert several WebP files to PNG at once?

Yes. Choose or drop as many as you like. They convert one after another, and once two or more are done, one button downloads them all as a ZIP.

It says my .webp file is already PNG. How?

The converter reads the bytes inside the file, not its name, and that file is really a PNG with the wrong extension. Rename it to .png and it will open where you need it. A JPG with a .webp name is simply converted to PNG.

Why does it say the file could not be read?

The file is damaged, was cut short during download, or uses a variant the decoder does not handle. Saving the image from the website again usually fixes a cut-short file.
