About the PNG to WebP Converter
This free PNG to WebP converter shrinks PNG images into the modern WebP format so pages load faster. Google’s page-experience guidance rewards smaller images, and WebP usually beats PNG on file size while keeping transparency when you need it.
Unlike upload-based converters, every image stays on your device. Conversion uses the browser Canvas API — nothing is sent to our servers, so there are no daily free-tier caps and private screenshots never leave your machine.

Is there a file limit? No daily quota. Each file can be up to 8 MB, and you can convert up to 50 files per batch.
