Resize This easily resizes your Retina sized images to a normal size so that your friends and colleagues can view them normally on their non-Retina screens.

Simply drag-and-drop your images onto the Resize This icon in the taskbar and they’ll automatically be resized! It’s that easy.

- Replace the old sized image with the new size
- Create an additional image without deleting the original
- Take screenshots in both Retina and non-retina sizes at the same time
- Supports .PNG, .JPG, .TIF
- Launches on computer startup
- Not just screenshots, works well for photos too
- Allows batch image resizing (drag-and-drop many photos at once)
- Reduce file size
- Set default save directory

Doesnt work anymore after macOS Sierra upgrade

hello i’ve used this app for about a year as its the only one i could get to annotate and reduce image size when adding images to emails with outlook 2011. Now i’ve upgraded to macOS Sierra and it no longer works. Anyone considering upgrading note that you will probably lose your ability to use resize this.

Please fix.

Needs shorcuts and a way to turn off the file duplication feature

The app works OK, except the resulting resized images are a bit grainy.

My main complaint is that every screenshot taken with the app creates two files: one at large size, one at normal size. I can understand the reason behind this, but I’d like a way to turn that off. 99% of my screenshots are for sharing with others, so my default is the normal size. I don’t need two of every file, cluttering up my hard drive. Yes, I can go delete the extras, but I wanted this app because I wanted something that would simplify my workflow.

It would also be nice if this app came with a way to create a keyboard shortcut for taking a screenshot.

I decided to use Monosnap instead, because it does the same thing without creating duplicate files, it has more preferences options, and it also immediately brings up an image editor with every screenshot, so I can draw arrows or circles on the image, etc. ...Which I need to do almost all the time in my job. Oh, and Monosnap is “free” (with ads and an upgrade option).

If you don’t care about having an image editor, though, this app would be a great, simple solution, except for the duplicate files thing.

Do not buy!

This app does not work. It does not have options for resizing setting at all, ruins the photo and is not user friendly at all. There is no way to use or see any menu so it is useless. Buyer beware.
