I've been batch-resizing images through Preview (OS X) through the menu bar, but I want a simpler workflow, since I do this a dozen times a day.
What I want:
- Select a group of image files in finder
- Hit a button or two (menu item or keyboard shortcut) to do the following:
- Scale all the pictures to 600 pixels wide
- Save as JPG files at 75% quality
What I also want:
- All of the above, plus step a(1): Crop images to 200 pixel height
I can do all that manually, to a batch of files, through Preview. I can do it one at a time with some keyboard shortcuts in Photoshop or Pixelmator.
Automator (using Preview) can scale to 600 pixels on the longest dimension, but it doesn't let me specify width. (It can scale specifically to width before cropping height.) It can change to JPG, but it can't specify image quality. I also can't assign a keyboard shortcut to the whole process.
Is that my best option on a Mac? Can I accomplish this more efficiently through another app like Quicksilver?
