Questions

Is transparency kept in WebP?
Yes. WebP supports transparency, so transparent areas in your PNG stay transparent.
What does the quality slider do?
It sets the WebP quality from 50% to 100%, starting at 100%. Lower settings usually make smaller files with more visible compression, so compare a couple of settings for your images.
Will the WebP always be smaller than my PNG?
Not always. It depends on the image and the quality you choose. Each result shows its size and the percentage difference from the original.
Does the pixel size change?
No. The WebP keeps the same width and height as your PNG.
Are my files uploaded?
No. The conversion happens in your browser, and your files stay on your device.
