Photopus offers easy but powerful batch editing for your photos.
It can be a pain to try and edit your photos one by one, especially if you want to do something simple like renaming them. Photopus is a great application that makes batch editing a breeze. It also includes a ton of filters and effects to add to your photos.
You can easily import photos one by one or choose an entire folder. Unfortunately Photopus doesn't support drag and drop, which is a shame. You can crop, flip, rotate, and resize photos all at once. There are also a ton of different effects to choose from to apply to all your photos at once.
In use, Photopus is quick to process photos, even when applying filters to them. Photopus supports almost all file formats but you will have to pony up some cash for the pro version if you want to edit RAW images.
Photopus is a simple to use and speedy batch photo editor, which is great for simple photo batch edits.
