Published: May 20, 2025 · 5 min read
Choosing between WebP and PNG can be confusing. Both support transparency, both are widely used on the web, and both have their strengths. This guide breaks down the differences so you can make the right choice for your project.
What is WebP?
WebP is a modern image format developed by Google. It uses advanced compression algorithms (both lossy and lossless) to deliver smaller file sizes than traditional formats while maintaining comparable quality. It supports transparency, animation, and metadata.
What is PNG?
PNG (Portable Network Graphics) has been a web standard since 1996. It uses lossless compression, supports full alpha transparency, and is perfect for graphics, logos, and images that need sharp edges. It's universally supported across all browsers and platforms.
