Actions let you apply sets of commands and effects to images in one go. You record them once, then apply them with a single click or keyboard shortcut. You can take Actions to the next level by letting them work intelligently based on the images they’re applied to – using a feature called Conditional Actions. And you can apply them from outside Photoshop using Droplets.
Conditional Actions let you apply Actions to many images at once, working in different ways based on each image’s size, shape or other criteria.
