BMP is an uncompressed image format from Windows. Files are very large, so converting them saves a lot of space.
WebP is a modern format that makes images much smaller than JPG or PNG and supports transparency, but some older programs cannot open it.
Frequently asked questions
Is the BMP to WebP converter free?

Are my images uploaded to a server?
No. The conversion happens on your own device using your browser, so your images never leave your computer or phone.
