Unlike converting to JPG, WebP fully supports an alpha channel. Any transparent or semi-transparent areas in your PNG carry over exactly as they were, with no background fill applied.
PNG is the right format for logos, screenshots, and graphics that need exact, lossless quality or transparency — but it produces noticeably larger files than necessary once that image goes on a website. WebP was built specifically to solve this: it keeps transparency support while compressing far more efficiently than PNG ever can.
The size difference is usually dramatic, not marginal. A PNG icon or graphic that's several hundred kilobytes often shrinks by 50 to 80 percent as a WebP at quality 80, with no visible difference for most images. For a page with several PNG graphics — icons, logos, illustrations — that adds up to a meaningfully faster load, which directly affects Core Web Vitals scoring.
One thing worth knowing: WebP's default mode here is lossy, while PNG is always lossless. At quality 80 or above this is rarely visible, but if your image relies on perfectly sharp edges — fine text, thin line art — pushing the quality slider higher, or testing at 95–100%, is worth doing before publishing.
If you need to go the other direction — converting WebP back to a universally compatible lossless format — WebP to PNG handles that with full transparency preserved as well.
