Using Webp in Java or Converting Raw bytes

[Chestly]

Hey, Im a Java dev, Am currently working on a project that will require Small and lossless images on the web. I of course wanted to use WebP but couldnt find any API to convert a Regular Png or Jpeg image to Webp.

I also didnt see a way to convert a raw byte array or String to a webp from the command line, Which i could have possibly utilized. Is there some FrameWork for doing this already written in Java, Or is there another way to convert strings or byte arrays to the webp format, I really do not want to have to create a new file anytime i have to convert, then call a command line command and then get the contents of that image!

Thanks for the help!

This has come up a few times in the past, there are a few options. We have a simple SWIG based wrapper for the simple API [1]. There's also a java imageio wrapper [2]. The original bitbucket repo link seems to have gone bad on that one.

Let me know if either of those will work for your use case.
