I'm struggling with this. I have a lot of (big) images that I need to resize to a specific smaller demension. The important thing is to keep the aspect ratio and don't do any weird stretching to the images. Empty space should be filled with my background color.

What I normally do is something like;

• Resize canvas to 550x800
• (the image is now bigger than the canvas)
• Use the transform tool with alt+shift (to resize from center) until image fits perfectly into canvas size
• Fill transparant pixels with white background

This is too much custom work and doesn't really work with batch. Can I use photoshop's image resize or canvas resize to do this?

My attempts have all failed. The image is either not the right size or with the right size but with weird stretching/transforming.
