How do I change the picture size in OS X?

rfrankl · Dec 31, 2006, 02:26 PM

I am a Mac newbie and enjoying it more every day, but I can't always figure out how to do something on here right away that I used to be able to do on my PC. Usually once I do though, it is amazing how much easier it is on a Mac.

How do I change the image size and file size of a pic? Do I need a 3rd party application, or can I do it in iPhoto? I don't see any options for that. Thanks!

this will make it really easy for you to adjust image size. just drag and adjust. if you have trouble "just ask"

Another thing you can do is to pick the photo in iphoto and choose file->export. You can then specify what you want the image scaled to as well as choose from a couple file formats.

You can also choose to email the photo and it will allow you to pick between small, medium, or large.

If you open Automator, there's a Preview action for scaling images to a given pixel size or percent of original.

I use Pixen, closest thing to Paint you´ll ever find, very neat app, universal binary, launches in less than a bounce on my MBP.

Go go iphoto > select the photo that you want to change the pixel size > export > scale images no larger than > 800 x 529 > export > and it is done!

Install parallels and windows and use paint -- only kidding.

Assuming you are on Leopard, when you open any image in Preview, you can go to Tools --> Adjust Size.

This is how I do it also. MC

To change the size of a photo in iPhoto, select the photo and on the file menu - export - under size, choose custom, and underneath you can choose a max dimension in pixels if you want to. I needed a 120 pixel max photo and tried 4 different photo editing programs and it took hours to figure this out. The size of the file is much smaller if you use a small number of pixels.
