How do I convert WebP to BMP?

Upload your WebP file above. It is converted to BMP automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting WebP to BMP lose quality?

No new loss is added: BMP stores the picture exactly as it is. Detail that WebP compression removed earlier can’t be restored.

Will the BMP keep the transparent background?

No. BMP can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).

Will the animation be kept?

No. BMP can’t hold animation, so an animated WebP is saved as its first frame.

WebP was designed by Google for the web. Google measured lossy WebP files at 25–34% smaller than comparable JPGs, and WebP also handles transparency and animation.

Is the WebP to BMP converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

Why convert WebP to BMP?

BMP is lossless, so the converted image loses no further detail when you edit and save it again.
BMP is made for older Windows programs, embedded devices and tools that need raw pixels.

What to expect when converting WebP to BMP

BMP can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).
BMP can’t hold this animation, so an animated WebP is saved as its first frame.
Converting can’t bring back detail that WebP compression already removed: the BMP is an exact copy of the image as it is, usually in a bigger file.
