Frequently asked questions
Does PNG compression always reduce size?
Not always. PNG is lossless-oriented, so converting photographic PNGs to WebP may produce a larger reduction.
Can I keep transparency?
WebP and PNG can support transparency when the browser codec and source image support it.
Can I batch compress PNG files?
Yes.
