FastPictureViewer Codec Pack 3 alternatives | Website
One of the things that I still don't like at all about Windows is definitely the poor and small amount of supported thumbnail formats, compared to macOS. It's not a secret to anyone that macOS has an incredible advantage when it comes to a friendly environment for designers. And as one, FastPictureViewer Codec Pack is an essential tool in my work, and I don't know how I could live without it before. It extend the compatibility of the thumbnails to other new formats such as PSD, Ai, PDF and many more.
Just to keep in mind, this is an extra feature of FastPictureViewer, which is full image viewer for Windows, but I personally only use this codec.
