PixverterThe short answer
For websites, WebP is usually the better choice: lossless WebP files are typically about a quarter smaller than PNG, and lossy WebP with transparency can be several times smaller. PNG remains the safe choice for editing, archiving and software that doesn't read WebP.
Choose WebP when…
- Images go on a website or in an app where load time matters.
- You need transparency but want small files.
Choose PNG when…
- You will edit the image further or need pixel-perfect lossless output.
- The file goes into documents, older software or print workflows.
- You need maximum compatibility.
