Convert BMP files to WebP in seconds. WebP makes a BMP many times smaller and is accepted by every modern browser.
Drop one or more BMP files onto the page, or choose them from your device.
BMP has no transparency, so the picture stays solid. WebP makes a smaller file by discarding a little detail. The quality slider lets you choose between a small file and the best look; 90 is a good start.
Press Convert, then download each WebP file, or all of them as a ZIP.
BMP (BMP image). BMP is the simple bitmap format of Windows. It stores raw pixels with no compression, so the files are large, but almost any program can read them. It is best for older software and programs that only accept plain bitmaps.
WebP (WebP image). WebP is a modern format from Google. It can be lossy or lossless, supports transparency and usually makes smaller files than JPG or PNG at the same quality. All current browsers show it. It is best for websites, where smaller pictures mean faster pages.
Add your BMP file, check that the target is WebP, and press Convert. Then download the WebP file. It takes a few seconds.
