Why convert PNG to WebP?
PNG files can be very large, especially photos and big graphics. WebP often shrinks them by more than half, and sometimes by much more.
Unlike JPG, WebP supports transparency, so logos and graphics with transparent backgrounds stay transparent.
WebP is supported by all modern browsers, making it ideal for websites, apps and online stores.
