Frequently Asked Questions

Common questions about WebP and PNG

Is WebP better than PNG for websites?

For most websites, yes. WebP files are 25–35% smaller than PNGs at equivalent quality, which means faster page loads and better Core Web Vitals scores. WebP also supports transparency, making it a strong PNG replacement for web use.

Does WebP support transparency like PNG?

Yes, WebP supports full alpha channel transparency just like PNG. In fact, WebP with transparency produces significantly smaller files than PNG with transparency, making it ideal for transparent web graphics.

Can all browsers display WebP images?

As of 2024, WebP is supported by all major modern browsers including Chrome, Firefox, Safari, and Edge. However, very old browser versions may not support it. You can use the HTML picture element to provide PNG fallbacks.

Does converting PNG to WebP lose quality?

WebP supports lossless compression, so converting with lossless settings preserves exact pixel data. With lossy WebP, there is some quality reduction, but it is typically less noticeable than equivalent JPEG compression at similar file sizes.

Why would I ever choose PNG over WebP?

PNG remains the better choice for print workflows, professional design, archival purposes, email compatibility, and any context where you cannot control the viewing environment.
