About BMP to WebP

Convert bulky, uncompressed BMP bitmaps into compact, web-ready WebP. BMP files are huge because they store every pixel raw, so re-encoding to WebP at the quality you choose can shrink them dramatically with little visible difference.

The re-encode runs entirely in your browser with WebAssembly codecs. Your BMP never leaves your device, so even sensitive graphics stay private.
