Read and Write HEIC Files in Java with JDeli
JDeli Image Library adds HEIC support to Java, allowing you to read, write, and convert HEIC files without native dependencies. Java’s built-in ImageIO has no native HEIC support, meaning any Java application that needs to handle HEIC files must rely on a third-party library. JDeli implements HEIC support entirely in pure Java, with no native binaries, no platform-specific setup, and no risk of JVM crashes from native code.
Frequently Asked Questions
Does Java support HEIC natively?
No. Java’s built-in ImageIO cannot read or write HEIC files. JDeli adds full HEIC read and write support in pure Java.
Can JDeli read HEIC files in Java?
Yes. JDeli can read HEIC files and return a BufferedImage, which can then be processed or converted to any other supported format.
Can JDeli write HEIC files in Java?
Yes. JDeli can write BufferedImage objects to HEIC format. See the Java HEIC writer guide for a code example.
How do I convert HEIC to JPEG in Java?
JDeli’s convert method provides a single call to convert directly from HEIC to JPEG. JDeli handles the conversion entirely in Java with no native tools required.
Does JDeli support EXIF metadata in HEIC files?
Yes. JDeli can read and write EXIF metadata in HEIC files. When converting a HEIC file to another supported format, EXIF metadata is copied across automatically.
Does JDeli’s HEIC support require native libraries?
No. JDeli’s HEIC implementation is pure Java. It runs consistently across platforms without the JVM crash risk that comes from native-dependent alternatives.
Can JDeli use HEIC as a drop-in replacement for ImageIO?
Yes. JDeli is available as an ImageIO plugin, so existing code that uses ImageIO will automatically use JDeli’s HEIC support without any code changes. See the ImageIO migration guide for details.
