## What is QuadCropper?

This app contains a Photos extension to crop and deskew rectangles in a photo.  Since the rectangles may be skewed by perspective, the cropping tool allows individual placement of the four corners of the 2D quadrilateral -- and then deskews the contained rectangle.  This is useful for business cards or slides or book covers or the like which have been photographed at an angle.

The app mimics the functionality of the Photos extension and can access the Photos library or the camera to get an image.  One can also crop the image from any file.  Unless the image is retrieved from the Photos library, the app will store the cropped image to a user-selected file.

Corners can be nudged by tapping on the corner circles.  The corner will move by a pixel in the direction of the quadrant of the circle that was tapped on.

### 5/5 — Basic App. Simple UI. Excellent.

*2026-03-02, version 1.0*

I love apps that don’t try to do too much. This is exactly the little tool I needed. Thanks for your work.

### 1/5 — Distorter

*2026-01-08, version 1.0*

This is not a cropping tool it is a distorting tool.So you can drag around objects to different styles.For a crop tool way to slow doesn’t work absolutely not used to crop!

### 1/5 — Needs work

*2025-12-18, version 1.0*

This app crashes like crazy

### 5/5 — Great App

*2025-12-03, version 1.0*

Love QuadCropper, I run a projection art show and it makes it easy to de-skew photos and artwork that have been shot at a angle - (as in, grandma shot her artwork hanging on the wall with her cell phone).

  Thanks Robert - great app

### 5/5 — Works superbly!

*2025-06-04, version 1.0*

Modified photos remain in the library. Meta info is preserved.
The app does not offer “save as,” but you can revert back to the original. Alternatively, duplicate the photo first, then edit the copy.
