Convert PNG graphics to WebP for smaller web assets while keeping support for transparent backgrounds. WebP is selected by default here and can be changed in the toolbar.
Web-size use cases
WebP is a strong target for site images, product graphics, social previews, and transparent UI assets because it often weighs less than PNG while staying browser-friendly.
Transparency and compatibility
WebP can preserve transparency, unlike JPG. Most current browsers support it, but some older upload systems still require PNG or JPG instead.
Limitations to know
- WebP export depends on browser Canvas support.
- Choose JPG instead if the destination does not accept WebP uploads.
