Why convert

Why convert BMP to WEBP?

Much smaller files

WEBP is a compressed format. Converting from BMP typically reduces file size significantly with no visible quality loss.

Wider compatibility

WEBP opens on more devices and platforms than BMP. All modern browsers (Chrome, Edge, Firefox, Safari 14+).

Add transparency later

WEBP supports an alpha channel, so once converted you can remove or replace the background in any image editor.
