Most free Photoshop actions will download as zip folders. You'll want to download this and extract the contents (which should take the form of an .ATN file) to an easy-to-find location on your computer.
To install the Photoshop actions and make them available to use in Photoshop, you'll need to select the Window Menu in Photoshop and choose 'Actions'. Click on the Menu Icon at the top right of the Actions panel, scroll down to Load Actions and open the Photoshop Actions Folder. Navigate to the folder where you saved the Photoshop action and double-click the .ATN file. Once the action you want appears listed, you can simply click the Play button.
The best free Photoshop actions can save you a lot of time if you're aiming to create a particular type of effect in Adobe's industry-standard image editing software. While doing it yourself can be time-consuming, Photoshop actions bundle in all the changes and processes needed to achieve a result while still allowing some fine-tuning once they've been applied.
