How to read Heic files in Java (Tutorial)

How to read Heic files in Java?

In this article, I will explain how to read HEIC files into Java as a BufferedImage. We also have a related article covering how to write HEIC files in Java.

ImageIO does not read HEIC file types so you will need to use an external library. In this article we will cover using our JDeli library to read Heic files in Java.

If you are looking for a free solution, we recommend the Nokia library on GitHub (which includes Java wrappers).

How to read Heic files in Java:

1. Add JDeli to Your Project: Add JDeli to your class or module path. (download the free trial jar ).
2. Point to Your Heic Picture: Create a file handle, input Stream pointing to the raw Heic image. Alternatively, you can also use a byte[] containing the image data if your data is in that format.
3. Read Heic pictures easily: Use JDeli to read the Heic image into a BufferedImage.

and the Java code to read Heic…

File heicFile = new File("/path/to/image.heic");
BufferedImage image = JDeli.read(heicFile);

Try print the result: if it works, it will print the image information

// Read an image
BufferedImage bufferedImage = JDeli.read(dicomImageFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(heicImageFile);

// Write an image
JDeli.write(bufferedImage, "heic", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpegImageFile);

// Write an image
JDeli.write(bufferedImage, "jpeg", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpeg2000ImageFile);

// Write an image
JDeli.write(bufferedImage, "jpx", outputStreamOrFile);

// Write an image
JDeli.write(bufferedImage, "pdf", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(pngImageFile);

// Write an image
JDeli.write(bufferedImage, "png", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(tiffImageFile);

// Write an image
JDeli.write(bufferedImage, "tiff", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(webpImageFile);

// Write an image
JDeli.write(bufferedImage, "webp", outputStreamOrFile);
