How to write BMP images in Java (Tutorial)

Why do BMP Images cause problems for Java Developers?

ImageIO supports BMP images but offers very little control over output.

What options are there for supporting BMP files in Java?

Java does have some support for BMP files in ImageIO. There are also Open Source and Commercial options available, including Java wrappers on non-Java solutions.

We recommend JDeli because it is a pure, complete Java implementation with no known security issues. It can be used with existing ImageIO code and has an API to write new code so we will document that in this article. It can also read BMP files and supports several other complex Image formats such as AVIF, HEIC and WEBP.

How to write out an image as a BMP file in ImageIO

1. Create a File (or OutputStream) object
2. Pass image, BMP type and File (or OutputStream) object into write method

and the Java code to write BMP with ImageIO…

File file = new File("/path/to/image.bmp");

ImageIO.write(bufferedImage, "BMP", file);

• Download the JDeli trial jar with our ImageIO plugin
• Follow the support documentation to install

How to write out an image as a BMP file with JDeli

1. Add JDeli to your class or module path. (download link to the trial jar).
2. Create a File (or OutputStream) object
3. Pass image, BMP type and File (or OutputStream) object into write method

and the Java code to write BMP with JDeli…

File file = new File("/path/to/image.bmp");

ImageIO.write(bufferedImage, "BMP", file);

JDeli.write(bufferedImage, "BMP", file);


//In JDeli you can also use a typesafe version

JDeli.write(bufferedImage, OutputFormat.BMP, file);


//or pass in a BmpEncoderOptions object for more control

BmpEncoderOptions options = new BmpEncoderOptions();

JDeli.write(bufferedImage, options, file);
