Hi so I'm looking for a simple mac app which will allow me to quickly change aspect ratio of images & preview them, according to various Instagram / FB/Twitter size requirements.

For example in Instagram the aspect ratios required by IG are:

4:5 to
1:1
5:4
4:3
3:2
16:9
1.91:1

Can anyone help me with any app for the mac? Thanks!

Any image editor, including Apple's pre-installed Preview app can crop a photo. In your case, you need one that allows you to manually enter Aspect Ratio numbers. I know Photoshop allows you to do this, but that's way overkill for your simple needs. You could use an online image editor like Pixlr X, which will allow you to simply enter the aspect ratio numbers to crop. It even offers presets for most major social media sites (for example, you can simply choose "Facebook Post Image).
