Right now I want to make something smaller that I scanned, but I’m always needing to do this and I’ve never known how.
Open the image in Preview.app and go to Tools—> Adjust Size and then resize the image and save.
Edit :: And you can crop an image by making a selection with one of the “Select” tools and using Tools—> Crop.
i also like using rapidoresizer, works pretty nifty
Image Shackle Widget
I use it almost daily.
just so you know, the shortcut to crop is apple key and K after you select the portion you want
yeah, I can crop it, I really wanted to just be able to resize the whole image, and the preview thing worked great, thanks jp.
