Despite the simplicity, this tiny (300kB) freeware tool can do a lot: resize by percentage, longest side, shortest side, width, height, fit in frame, or by specifying file size in kilobytes. Batch processing of files in all subfolders, generating custom reports (e.g. htlm fragments for galleries), sharpening and more. Usable as a droplet or from Explorer's context menu.

New features:

* Multi-core CPU support for extremely fast batch resizing.
* Changing aspect ratio while preserving content using image seam carving.
