"I work for a blueprint company and sign shop. We are always looking at size limitations imposed by the customers. This is the best answer to all the "what if it was" questions. Also the customer and I can see quickly how pixilated an image would become if it gets blown up too big without expensive graphic software. Some software developers go above and beyond, thank you for adding this great feature to an already amazing app."

### 5/5 — Keep your images proportional.

*2025-03-11*

I am constantly resizing pictures for frames. It makes it so easy when you know the exact measurements you’re working with and where you need to make editing decisions.

### 5/5 — Great app!

*2025-02-06, version 3.6*

I use this to scale down. If I have a 30x40 canvas, what size should my sketch be in order to keep it to scale? This app is quick and easy to use! In the studio or out in the field. It’s absolutely great for what I use it for! Still love this app! I also now use it to scale up. If I’ve painted something small and want to blow up to large canvas but keep the scale, what size canvas do I need to buy? Works great!!
2/2025 been using this for yrs now!  Still love it! So easy to use!

### 5/5 — THIS IS THE BEST APP FOR SIZING IMAGES

*2019-05-19*

I've usually only,done reviews when prompted but I saw this only has 13 reviews when I went to reinstall it and HAD to review it because it is my GO-TO app to resize anything. It's SIMPLE EASY TO USE AND WORKS IN A SNAP! I can't believe it's only got 13 reviews, I've been using it for years and will never use anything else.

### 1/5 — Can't Access Upload

*2017-09-06*

When I resize the image and go to upload I can't access the image. Thought it would appear in Photos app but is nowhere to be seen! Disappeared into the crap app ether!!

### 5/5 — Amazing

*2017-03-22*

After 3 minutes I hadn't figured out how to export the scaled images and tried to give this a one-star rating, got asked for feedback and tried again -- found the image export.  The 200% enlargements are beautiful.  I don't really understand why anyone would want to just look at images that are 10 times bigger, but it doesn't matter.

### 5/5 — Perfect for my needs

*2017-01-18*

I have a project in which I have to rescale many photos for publication. Apparently my wheel calculator has been lost in the mist of time. This app easily provides the math which is all I wanted.

### 5/5 — an app that scales properly - LOVE IT

*2016-07-28*

Before I found this great app, I tried several that claimed to "resize" but, instead, "cropped."

Finally, I found this one!  Not only did the developers understand that "resizing" means "scaling" the entire photo without chopping off any of the sides, IN ADDITION, they understood the need to keep everything in proportion as it is being scaled.

It is exactly what is needed for quick resizing on the iPad.  Simple, fast, easy.

Note:  If you need to pick a specific interpolation method, you'll need an app with a fuller set of features, but for almost all of us, this app, is perfect.

### 5/5 — As good as the wheel!

*2016-02-25*

Round, white, plastic proportion wheels were often give-aways from Specialty Advertising companies. They were absolutely indispensable. They were marked with inches in mind and had base eight divisions. This app does it, and it does it with base 10 (decimal).
