About this converter
A BMP screenshot can be fifty times larger than the same picture as a WebP, which is why websites and messaging apps reject BMP uploads outright. This converter re-encodes BMP files as WebP locally, with a quality setting you control, so a picture from an old Windows program becomes a small, modern file ready for the web.
