A resizer tool to automaticaly resize png files and 9 patches in several densities (previously hosted on

Build Status


To get the latest build (.jar or .exe file), check the release page on the github project:

The .exe file is just a wrapper around the executable .jar file, use it if you don't feel comfortable with a java archive ^_^

What is it exactly?

Let's face it : juggling with densities for Android is a bit of a pain, especially when dealing with 9 patch png.

And then comes this tool, that takes a xhdpi PNG file, or 9.png file, and generates ldpi, mdpi and hdpi png files automatically.

As simple as drag and drop can get.

And here is the changelog

Current version : 1.4.2

You're using 9patch resizer for your apps ? Don't hesitate and leave me a message!



I'll be honest, I don't really maintain 9-Patch-Resizer anymore, as 9-patch are somewhat a thing of the past, and I use as many vector drawables as possible lately.

I will of course consider bug fixes, but I might not have the bandwidth for feature requests.

Sorry about that.

  • A proper "Settings" panel, to handle issues such as jpeg compression, etc etc...
  • A few optimisations
  • Command line support
  • Options to set the input density (if people wan't to downsize from hdpi and not from xdpi for instance)
  • Proper JPG support


  • redwarp
  • Jean-Baptiste LAB - Made the app working in command line

Join us, and together, we can rule the galaxy as coders and...
