Convert BMP to WebP
Drop a BMP file and get a WebP back. The conversion happens in this tab, so there is no upload, no queue and no limit on how many you do.
Your image never leaves your device. Everything happens in this tab.
What changes in the trip
BMP. Uncompressed, so enormous: a plain dump of every pixel. Almost nothing produces them any more, and converting one to almost anything else will shrink it dramatically.
WebP. Smaller than both PNG and JPG at the same visual quality, and it keeps transparency. Every current browser displays it, though some older desktop software still will not open one.
