Resizing pictures is especially useful for printing, or to maximize storage space. Going through all your big photos and resizing them one by one by one takes a lot of time and effort. Now you can use the power and versatility of Adobe Photoshop to batch resize your photos and images.

Steps

Photoshop offers two functions that make batch resizing easier: recording actions and batch automation. Recorded actions apply a sequence of commands or editing steps on an image file, while batch automation applies the recorded action to all image files in a folder. To make Photoshop do all the resizing work for you, follow these steps:

Recording Actions

Select one of your image files, and open it in Photoshop.
The “Actions” tab is found beside the “History” pane on the right-hand side of the screen. If you don’t see this tab, press Alt+F9 repeatedly until the tab appears.
Click “Create New Action” on the Actions pane. Name your action, and click “Record.”
Go to the “Image” menu on the menu bar, and click on “Image Size.”
Resize the photo depending on your desired picture size. It’s best to keep the proportions constrained to avoid distorting the image.
As soon as the image is resized, stop recording the action by clicking the “Stop” button on the Actions pane.

Batch Automation

Go through the pictures one by one first to check their orientation. They should all have the same dimensions, and should be oriented in the same way as the picture you first applied the action to. Move or copy them all into a single folder.
From the Photoshop window, click “File,” then click “Automate.” Select “Batch” from the side menu.
Set the Action, and select the source folder.
Click OK, and Photoshop will resize all the photos in that folder automatically. It will take a while depending on the speed of your computer, and the file sizes of the images.

With Photoshop, batch resizing big photos becomes simple and efficient. With batch resizing, you can save a lot of time, effort, and precious space on your hard drive or memory card.
