SageThumbs is a powerful shell extension allowing to preview enormous amount of image formats directly in Windows Explorer by using Pierre-e Gougelet's GFL library (XnView's author).

Please read carefully the following information:

As SageThumbs is a Windows Explorer context menu extension, there is no an executable file that you should launch to bring it up.

  • Превьюшки всех нужных графических файлов Настраиваемое контестное меню для проводника

  • Great image viewer for HDR images

  • Good, but could be better. There is only one problem: no other (free) project like this.

  • I'm really like the image preview in Explorer right-click menu as well as the extended information tips! As a graphic designer, I find it so easy to use. Furthermore, for such problems like can't open or rename file (name is too long prompt), I use Long Path Tool and it works.

  • Good, very useful software. But : no miniature visible in the windows 10 browser so support about webp image format Thank you for your work
