Frequently Asked Questions
Does WebP preserve PNG transparency?
Yes. WebP supports an 8-bit alpha channel, so transparent logos and graphics convert cleanly.
Which is better: PNG or WebP lossless?
WebP lossless is usually about 26% smaller than PNG at identical quality, making it the better choice for websites.
Can I convert PNG to WebP lossy?
Yes. For photographs or complex images, lossy WebP at quality 80-90 looks nearly identical but is much smaller.
