How to Convert BMP to WebP
Add your BMP file

Choose WebP as the output
Choose WebP as the output format. In UniConverter Desktop, review the supported image settings and adjust dimensions when your publishing workflow needs a specific width or height.

BMP vs WebP: Which Format Fits Web Publishing Better?
BMP is an older bitmap format that is commonly stored with little or no compression, so files can be large. WebP is a modern image format designed for the web and supports both lossy and lossless compression, plus transparency.
