WebP vs PNG
Choose the right format for transparent graphics, screenshots, and faster website images.
WebP and PNG can both handle transparent graphics, but they solve different problems. PNG is a dependable lossless format for source files, screenshots, UI graphics, and editing workflows. WebP is a modern web delivery format that can keep transparency while usually reducing file size. For websites, the question is often not whether PNG is bad, but whether the public page should serve a lighter WebP version while keeping PNG as the original.
Choose WebP when
- You publish images on a website and want smaller page weight.
- You need transparency but also care about loading speed.
- The image is going into a modern CMS, shop, or browser-based workflow.
Choose PNG when
- You need a lossless source file for editing or archiving.
- The image contains sharp UI details, text, or screenshots.
- You need maximum compatibility with older software.
Compression
PNG uses lossless compression, which preserves every pixel but can create large files. WebP supports lossless and lossy compression, so it can often produce smaller web images at similar visual quality.
Transparency
Both formats support transparency. That makes WebP a practical replacement for many web-facing PNG logos, icons, and graphics, as long as the target software supports WebP.
Workflow
Keep PNG for source and editing workflows, then convert to WebP for public website delivery. This gives you compatibility and performance without losing the original file.
Use PNG as a reliable source format. Use WebP for web delivery when smaller files and faster loading matter.
