About this tool

BMP to WebP takes the largest common image format and turns it into one of the smallest. If you are putting old scans, screenshots or graphics on a website, WebP gives a far lighter file than BMP - and lighter than JPG or PNG in most cases - while every modern browser displays it. Expect a dramatic size reduction. WebP is lossy at a quality that keeps photos looking the same, and while a BMP has no transparency to bring across, the WebP can hold it if you edit the image later.

From archive file to web-ready image

BMPs are common in archives, exports from legacy systems and scanner folders, but they are far too heavy for the web. WebP makes them publishable in one step. Keep the BMP or a PNG copy as your master if the images are originals you may need to edit or print later.

WebP is a lossy format, so a small amount of detail is discarded. At the quality this tool uses that is invisible on a photograph, but fine text and sharp edges - screenshots especially - can soften slightly.

Files usually come out noticeably smaller, because WebP compresses much harder than BMP.
