Frequently Asked Questions

Which image formats are supported by Thumbnailator?

The image reading and writing functionality of Thumbnailator is dependent on the capability of the Java Image I/O API which the library uses.

By default, Java 6 and beyond support reading and writing of JPEG, PNG, GIF, BMP and WBMP formats; Java 5 did not support writing GIF files.

List of supported formats for each Java release:

The Image I/O API has a plug-in mechanism to support additional image formats.

As Thumbnailator uses the Image I/O API, by using additional Image I/O plug-ins, it is possible to support more formats from within Thumbnailator.

For example, the TwelveMonkeys ImageIO library provides additional support for many image formats which are not by default in the Java runtime.
