With the number of blogs and personal webpages it's no longer only us, software reviewers, who need to resize many pictures on a daily basis. You probably need to resize a lot too, to send them by email, publish them online and many other possible usages.
This is where Squash comes in handy, enabling you to resize photos in batch mode, that is, many of them at the same time. The program, which doesn't even require installation, features a simple design and is very easy to use: simply open the photos you want to resize on its interface, select the new size, add a suffix if you want and you're done.
Of course, this simplicity of usage has also certain somewhat negative consequences: experienced users may miss having a few more options – at least to select the picture's new size, which only works in percentages. Also, the interface doesn't support dragging and dropping of images, something I personally found a bit of a shame.
If you're looking for a simple, quick way to resize photos, this may be the tool you need, though sometimes it seems it's just too simple even if it's only intended to resize pics.
