WebP vs PNG: which should you use?

Compare WebP vs PNG for web images. Learn when to keep PNG, when to convert to WebP, and how compression impacts quality.

PNG is a lossless image format that’s excellent for transparency, sharp UI, and screenshots. The downside is file size: PNG can be much larger than necessary for web delivery.

WebP is a modern image format designed for the web. It can compress images much smaller than PNG while keeping good quality, and it supports transparency too.

If you need pixel-perfect results (like UI assets), keep PNG or use a palette PNG preset. If you’re optimizing a website, converting PNG to WebP is often the fastest way to improve page speed.

For photos, WebP or AVIF usually wins. For graphics and text-heavy screenshots, test both formats to avoid ringing or blur.

FAQ

Does WebP support transparency like PNG?

Yes. WebP supports alpha transparency. Convert PNG to WebP when you want transparency with smaller file sizes.

Why does my WebP look blurry?

If you used lossy compression with low quality, edges and text can blur. Increase quality or use lossless WebP for UI/screenshot content.
