Instant Resize

By Kai Luo

Open the Mac App Store to buy and download apps.


Instant Resize is probably the easiest way to resize images, just drag and drop them to the app icon then choose a proper size, you are done!

If the target size has a different aspect ratio, the app will automatically crop the right part then resize it.

Where is the image?

The app is easy to use but does not show the resized image after resizing. The page is blank. Tried going to the website listed above as suggested for help and there is nothing there but a page advertising the app (they even spelled ‘available’ incorrectly). No support. I’m afraid I got scammed. Do not purchase this app. It does not work.

Works but needs polish.

Go to File menu.
Select Open.
Navigate to picture.
Select picture.
Click Open.
Fill in Size (it's in pixels).
Click Resize.
