How to Convert AVIF to JPG in Bulk (Tutorial)

If you’re working with a large number of AVIF files, converting them to JPG in bulk can streamline your workflow, especially when the JPG format is required for multiple applications.

You can read, write and convert AVIF files in Java with JDeli, our pure Java library.

AVIF (AV1 Image File Format) is a modern image format offering superior compression efficiency compared to JPEG and PNG. Converting images to AVIF results in significantly smaller file sizes with high visual quality. This leads to faster loading times and reduced bandwidth use on the web and other platforms.

In this article, I’ll show you how to convert AVIF images to JPG using Java and JDeli, making your files easier to work with. JDeli stands out as one of the most powerful Java libraries for handling and manipulating images.

Bulk convert AVIF to JPG using Java

1. Download the JDeli trial jar.
2. Process image if needed (scale, sharpen, lighten, watermark, etc)
3. Write out BufferedImage as JPG image file

BufferedImage bufferedImage = JDeli.read(new File("avifImageFile.avif"));

// Read AVIF image into Java


bufferedImage = operations.apply(BufferedImage bufferedImage);

// Process image (Optional)


JDeli.write(bufferedImage, "jpg", new File("jpgImageFile.jpg"));

// Write out BufferedImage as JPEG image file

Export AVIF to JPG in one line of code

With the JDeli.convert() method you can save PNG as JPG in just one line of code.

Using File

JDeli.convert(File inFile, File outFile);

JDeli.convert(InputStream inputStream, OutputStream outputStream, "jpg");

byte[] outputData = JDeli.convert(byte[] inputData, "jpg");

JDeli.convert(File inFile, EncoderOptions outputOptions, File outfile);

How to bulk convert AVIF to JPG from the command line

You can turn PNG to JPG using command line or bash, bat, and PowerShell scripts. This method also enables JDeli to be invoked from any programming language that supports creating a child process.

java -jar jdeli.jar –convert jpg "inputFileOrDir" "outputDir"

In this tutorial you learned how to bulk convert AVIF to JPG in bulk. JDeli has AVIF support for reading and writing as well, you read our documentation to find out more.

As experienced Java developers, we help you work with images in Java and bring over a decade of hands-on experience with many image file formats.

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

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

// 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);
