In this article, we will show you how to read GIF files in Java. We also have a related article covering how to write GIF files in Java.

GIF files can be read directly by Java’s own ImageIO class and we will also show you how to read them in JDeli.

How to read a GIF image in Java with ImageIO

Create a File handle, InputStream, or URL pointing to the raw GIF image.
ImageIO will now be able to read a GIF file into a BufferedImage.

and the Java code to read GIF with ImageIO…

File gifFile = new File("/path/to/image.gif");
BufferedImage image = ImageIO.read(gifFile)

How to read a GIF image in Java with JDeli

Add JDeli to your class or module path. (download the trial jar).
Create a File handle or InputStream pointing to the raw GIF image. You can also use a byte[] containing the image data.
Read the GIF image into a BufferedImage

and the Java code to read GIF with JDeli…

File gifFile = new File("/path/to/image.gif");
BufferedImage image = JDeli.read(gifFile);

Other than providing GIF support for reading, you can also use our pure Java image library for converting and writing GIF files by looking at the documentation on our support site.

Are you a Java Developer working with Image files?

// 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);

What is JDeli?

JDeli is a commercial Java Image library that is used to read, write, convert, manipulate and process many different image formats.

Why use JDeli?

To handle many well known formats such as JPEG, PNG, TIFF as well as newer formats like AVIF, HEIC and JPEG XL in java with no calls to any external system or third party library.

What licenses are available?

We have 3 licenses available:
Server for on premises and cloud servers, Distribution for use in a named end user applications, and Custom for more demanding requirements.

How does JDeli compare?

We work hard to make sure JDeli performance is better than or similar to other java image libraries. Check out our benchmarks to see just how well JDeli performs.
