Batch Processing in Photoshop

Batch processing allows you to perform an action, such as resizing, to all image files in a specified folder.

Getting Started

  • put all of the images you want to batch process into one folder on your computer
  • make sure they are all right side up
  • boot Photoshop and open one of the images in your folder

Method 1: Image Processor

A quick tool to resize all images in a folder.

  1. choose: File > Scripts > Image Processor
  2. select the folder containing your images (1)
  3. select a location to save the processed images (2)
  4. select Save as JPEG and Resize to Fit (3)
    in the width box, enter 555 pixels (or max desired width)
    in the height box, enter 800 pixels (or max desired height)
  5. click the Run box in the upper right hand corner

This will save your images at the proper size for uploading to your WordPress site.

Method 2: Macros

For more complicated jobs, where multiple actions need be performed on each image.

Create the macro

    1. open one of the files you want to modify
    2. open the actions tool: window->actions
    3. create a new action by clicking the new page icon- name it ‘resize for web’ and click record.
    4. modify the image
      • open up the image->image size tool
      • at the bottom, check off “Resample Image” and select “Bicubic sharper (best for reduction)”
      • check off the  ”Constrain Proportions” box so your image doesn’t get distorted when resizing.
      • reduce the resolution from 300 to 72
      • reduce the width to 350 px (you may have to change the measurement units to be points), click OK
      • select image->adjustment->auto levels
    5. save the image
      • file->save as and put it in the ‘web’ folder
      • if you are working with a  jpeg file, select image quality (8 is fine), and click ‘OK’
      • stop recording (hit the square button in the action tool)

Apply the macro to files in a folder

    • file->automate->batch
    • in the ‘Play’ section, select the action you just created (2nd pulldown)
    • Source: folder
      • select the originals folder
    • Destination: folder
      • select the web folder
      • check off Override Action “Save As” Commands
      • file naming- we just want the file named the same thing in a different folder no changes here.
    • click OK
