PNG vs WebP: Which Format Is Better for Websites?
PNG and WebP are both common on websites, but they serve different priorities. PNG is often chosen for editing quality and transparent graphics, while WebP is usually preferred when smaller files and faster page loads matter more.

Where PNG Still Wins
PNG is still a strong choice for screenshots, interface elements, logos, and other graphics that need crisp edges or reliable transparency handling.
Because PNG is lossless, it is also easier to keep around as a working format during editing or design handoff before exporting to something smaller for the web.
Why WebP Is Often Better For Delivery
WebP is usually the better format for actual website delivery because it often produces noticeably smaller files than PNG. That helps pages load faster and reduces bandwidth use, especially on image-heavy pages.
For many web graphics, product images, and content images, WebP can keep visual quality high enough while making the page more efficient overall.
How To Decide
If the image needs transparency and you are still actively editing it, PNG is often the simpler working format. If the image is ready for publishing and you want a smaller file, WebP is often the better delivery format.
In practice, many teams keep source artwork in PNG and then convert finished images into WebP for website performance.
