This plugin allows Paint.NET to load and save Google's WebP format.
During testing it saved over 200KB vs JPEG at 95% quality.
(EER Edit) To install place all three dlls from the download in the FileTypes folder.
The Visual C++ 2010 SP1 runtime is required to run this plugin (x86 for a 32-bit OS, or x64 for a 64-bit OS).
When the quality slider is 100 lossless compression is used.
I hope it is useful.
