Auto Crop Images

Auto crop image editing is a time-saving technique that automatically removes unwanted areas from your files.

How to automatically crop images with reaConverter

This feature identifies the main subject in your image and crops it accordingly, leaving you with a perfectly framed picture. With auto crop image editing, you no longer have to spend time manually cropping your files, allowing you to focus on other aspects of your work. Try this feature out and see how it can help streamline your editing process.

1. Open Images

Add all the image files you intend to crop, either by browsing your computer or using the drag-and-drop tool. Alternatively, you can add entire folders here, or load files from a .txt file-list.

2. Add Auto Crop Action

Go to the Image editing tab, press the + add action button and pick Alteration and Orientation from the dropdown menu, and then click Auto Crop.

Now you will be able to easily detect the area you intend to crop by selecting the color of pixels from the top-left, top-right, bottom-left or bottom-right part of the image. Or by selecting one particular color using the handy color picker tool directly on the preview image. Here you can also enter a particular color tolerance, if you like.

3. Save the Result

In the Saving options tab, you will find several possibilities in terms of locating your cropped images. Choose a local folder, your could-service account or several other options. Then decide if you want to preserve the initial format of your images or convert them to another one by simply selecting the extension from formats list.

After this is done, just click Convert and your cropped images will be ready sooner than you expect!
