QUESTIONS
PNG-to-WebP questions
Will transparency be preserved?+
Yes. Transparent PNG pixels remain transparent in the WebP output.
Why is WebP often smaller than PNG?+
WebP supports more efficient compression. The exact reduction depends on the image and the quality setting you choose.
Should I keep the original PNG?+

Are my images uploaded?+
