Crop an image in java

In this article, I will show you how to crop an image in Java using just ImageIO or JDeli.

Crop an image in Java with:

ImageIO

  1. Load the image file using Java ImageIO (which is built into Java)
  2. Get a cropped version (x, y, width, height) (0,0 is top left corner)
  3. Save the image back to a File

Note it is important to save the image before applying any other changes as the BufferedImage object is shared between the original and new crop object.

JDeli

  1. Create a Crop ImageOperation in JDeli (here is how to setup JDeli)
  2. Get a cropped version (x, y, width, height) (0,0 is top left corner)

And that is all you need to do!!!

Below is an example of the cropped and original image

You can also extract GPS data from an image, here is a simple guide to show you, with multiple different tools.



Are you a Java Developer working with Image files?

Why do developers choose JDeli over free alternatives?

  1. Works with newer image formats such as AVIF, HEIC, JPEG XL, WEBP
  2. Better support than alternatives for JPEG, PNG, TIFF.
  3. Prevent JVM crashes caused by native code in other image libraries
  4. Better performance than other popular Java image libraries
