Size Does Matter: Batch Reducing Many Images

In ITServices Fall 2010 Newsletter "Tech Tip", readers were presented with instructions on how to resize a single image using Photoshop. Resizing images to make them smaller allows you to send them to friends as email attachments without the email bouncing back to you because the image was too large.

 

But what if you have a lot of very large images that you would like to upload to a web site or import into a document? It would be very time consuming to reduce them, one at a time!

 

This article demonstrates how you can resize multiple images all at once using Photoshop.

 

Step 1. If you have a lot of pictures that you want to resize you can do this through Bridge in a batch. Launch Bridge from within Photoshop by clicking on the bridge button "Br" as illustrated in the picture below with the red arrow.

 

 

Step 2. Navigate to the folder where the pictures you want to resize are located.

 

Step 3. Select the pictures you want to resize (hold down the Ctrl key and click on individual pictures or press Ctrl A to select all pictures in the folder.). Once all of the pictures that you want to resize have been selected, go to the top of the window and select Tools > Photoshop > Image Processor. This will bring you back to Photoshop with the following dialog box displayed. Follow the selection instructions indicated in red and marked from Ato E.
