Ratings and Reviews

Outstanding app


This app is terrific. It handles resizing graphics with ease. It can handle single graphics or batches of graphics. Excellent!

Efficient image resizer!


This app does what it says it will do and it does it spectacularly well! I was looking into other similar software on the App Store and saw that all of the other apps were priced at around $10 so I downloaded this to see how much this free program would help. I am not disappointed!

Click-and-drag makes this really easy to use. I wanted to batch-resize photos for thumbnails for my site and all I needed to do was drag them onto the app, select my preferences, and select a destination folder. It works very well and is surprisingly more feature-rich than what I expected for a free app. I would highly recommend this to anyone looking for a simple batch image resizing tool!

No long/short edge resizing


I need an app to do what Mac Preview can’t, which is long edge resizing. Unfortunately Resize Master can’t do that. I’d rather the 'fit to a rectangle option' be able to apply to portrait or landscape orientation as needed.
