TwelveMonkeys ImageIO is a collection of plugins and extensions for Java's javax.imageio framework, adding read/write support for many image formats not covered by the JDK, such as TIFF, PSD, WebP, and PICT. It is a mature, BSD-3-Clause-licensed Java library distributed via Maven Central.
Use cases
- read TIFF and BigTIFF images in Java
- open Photoshop PSD files from a Java application
- add WebP decoding support to javax.imageio
- handle legacy image formats like PICT, PCX, and TGA in Java
- read ICC color profiles and image metadata
- convert obscure image formats to PNG or JPEG on the JVM
When to choose
- your Java app needs to read or write image formats the JDK doesn't support
- you need robust TIFF/BigTIFF handling with metadata on the JVM
- you want a drop-in ImageIO plugin with no native dependencies
When to avoid
- you need a standalone image converter CLI or GUI
- your project is not on the JVM
- you need full WebP or PSD write support (mostly read-only)
