When it comes to resizing a large batch of images on your computer, you can download an app that does that and only that, you can use an online service, or if you already have Photoshop on your computer, you can easily get the job done.

Photoshop ships with this feature, which is hidden away in the File menu.

Step 1

Go to File > Scripts > Image Processor.

PS1

This will open up a dialog where you can choose the photos you want to resize. You can either resize images you already have open, but where this feature really shines is the ability to select a folder which contains all the images you want to resize.

PS2

Step 2

You can choose to save the images in the same folder, in which case Photoshop will create a subfolder for those images. Alternatively, you can choose a specific folder where you can save the images.

Step 3

When it comes to the details of the images, you can save them as JPGs, TIFFs, or PSDs, and you can choose the specific width or height. With JPGs you can also select the image quality.

Step 4

Once you've got all your settings in place, hit the "Run" button, and sit back and let Photoshop do all the work. If you want, while resizing the images, you can also batch run a Photoshop action on the images.
