Free WebP to BMP converter online
Need a BMP instead of a WebP? This free converter turns WebP files into BMP images right in your browser. Add as many files as you like, adjust the settings and download the results individually or together as a ZIP.
WebP is a modern format created by Google for the web. It is typically 25 to 35 percent smaller than an equivalent JPG and supports transparency and animation, which is why so many websites now serve it. The downside is compatibility: older versions of Photoshop, Windows Photo Viewer, many printers and lots of upload forms still cannot open WebP files.
BMP is an uncompressed bitmap format from early Windows. Because it stores every pixel raw, BMP files are enormous (a 12 megapixel photo is about 36 MB) but they are trivially simple, so old software, microcontrollers, label printers and some games still require them.

Will converting WebP to BMP reduce quality?
No further quality is lost. BMP is lossless, so the BMP file looks exactly like the decoded WebP (any compression artefacts already in the original stay as they are).
Can I convert multiple WebP files to BMP at once?
Yes. Select or drop as many WebP files as you like; there is no limit on the number or size of files.
Why do images from websites save as WebP?
Websites serve WebP because it loads faster. Your browser saves the image in the format it was delivered in.

Yes. The WebP to BMP is completely free with no sign-up, no watermarks, no daily limits and no premium tier.
Are my files uploaded to a server?
No. FileStripe processes your files locally in your web browser using JavaScript. Nothing is uploaded, so the WebP to BMP is safe for private photos and confidential documents and even works offline once the page has loaded.
