Frequently asked questions
Is WebP smaller than JPG or PNG?
It often is at comparable visual quality, but the result depends on image content, dimensions and encoder settings.
Does WebP support transparency?
Yes. WebP can preserve transparency when the source image and browser conversion path provide an alpha channel.
Will the original image be changed?
No. The converter creates a new WebP download and does not modify the source file on your device.
