Best way to read and write webp format images in java

Question

The normal Imageio Library says it cannot read the Webp format images. Are there any simple methods to read and webp images in java?

Found this library today: webp-imageio. Haven't tried it out yet, but it looks like it'll do encoding using ImageIO.

It seems it calls native code from java (it needs .so or .dll): it is not a standalone solution for java. :( – zenbeni Oct 29 '13 at 09:43

Is that the reason, why its not available in maven central repo ? – Milli Aug 31 '15 at 11:13

sprd-webp is another java JNI library based on webp-imageio. It is a wrapper around googles libwebp and not a real java implementation.

Java VP8 Decoder is a GPL3 library currently in beta that can read webp image format. It seems there is no encoding facility at the moment.

A possible alternative would be using VLCJ, a Java bindings library for VLC (webp support should be available out-of-box in lastest versions afaik).

A third library is jvp8, a dual-licensed commercial/GPL native wrapper which allows to use the VP8 video codec.
