FAQ
Why is the output so large?
BMP applies no compression at 3 bytes per pixel — the size is a property of the format, not a quality issue.
What happens to transparency?
24-bit BMP has no alpha; transparent areas are filled with white.
Does conversion need internet?
No — after the page loads, everything is computed locally, even offline.
About this WebP to BMP
Some industrial software, board utilities, legacy embedded systems and lab equipment only accept BMP. This tool decodes your WebP locally and encodes the most universal 24-bit BI_RGB BMP — uncompressed and readable by any Windows environment. Be aware BMP files are large (3 bytes per pixel; a 1080p image is about 6MB), so check the target device has room.
