Density Converter

App developers need to generate different versions of the same image when creating software for various platforms, as well pictures with multiple pixel densities for each platform.

Density Converter is an open-source application that can make this job a lot easier, as it is capable of converting large batches of images to the required formats. Featuring an intuitive GUI, this Java-based tool can also be used from the Command Line.

This is a great tool for developers who are building applications for several platforms, as you can convert all the original images to the necessary formats with very little effort. Just add the source folder, select the target platforms and launch the process.

Assuming the images you have at your disposal are in the highest resolution needed for the platform, you can select the Source Scale Factor mode and have the app generate the other versions automatically. Alternatively, you can set the width and height in DP manually.

If you want to have more control over the operation, you can switch to the Advanced mode and customize many other parameters. You can select the output format, image quality and rounding mode, as well as the maximum number of parallel threads.

You can enable anti-aliasing, perform a test run, clean the target directory before conversion, skip upscaling and customize other Android- and iOS-specific settings.

Density Converter offers support for a number of popular image formats, as it can process PNG, JPEG, GIF, SVG, PSD, TIFF and BMP files.

The application allows you to use several third-party tools to further enhance the resulting files, namely pngcrush, cwebp and mozJpeg. These must be present in the same folder as Density Converter; otherwise, the options will be disabled in the UI.

Advanced users also have the option of using the program from the Command Line, and the full list of supported arguments is available on the product’s homepage.

On the whole, Density Converter is a small but impressive application that can be invaluable for developers, as it greatly simplifies the task of converting images to formats required by various platforms.
