Another tool to resize multiple images, I Love IMG makes the process easy. Upload all of your images at once, then choose if you want to resize by pixels or percentage.

The By Pixels option offers a helpful feature, a checkbox that says, “Do Not Enlarge If Smaller.” For example, say you want all photos to be 800 pixels wide.
