PNG to WebP Converter
WebP is a modern image format developed by Google that typically produces files 25-50% smaller than PNG at the same visual quality, while still supporting full alpha transparency — making it a strong choice for website images where load time matters. This free PNG to WebP converter re-encodes your PNG file in your browser, so you can shrink images for a faster website without uploading anything or installing image editing software. Just drop a PNG, adjust the quality if needed, and download the converted WebP file.
