About this tool
Use this tool to convert PNG files into WebP format with strong compression while maintaining visual quality.
It is especially useful when you need faster image delivery at scale, such as blogs, e-commerce catalogs, and media-heavy landing pages.
Why WebP helps modern delivery

How to choose WebP quality
High (90-100)
Use when visual fidelity is top priority, such as hero images or detailed graphics.
Balanced (75-89)
Best default for most websites: good quality with meaningful size reduction.
Compact (60-74)
Useful when strict file-size limits matter more than fine visual details.
Important: Very high compression can introduce visible artifacts. Test a balanced quality range for best real-world results.
