ARSC is an Android application resource file. ARSC files are used by developers to store additional application resources. ARSC resource files contain static data, that is data that is not changed during application running process.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the IPR file after converting to ARSC may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from IPR to ARSC to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting IPR to ARSC does not meet your expectations, you can simply try to find on the Internet a different version of your file in IPR format, properly converted to a ARSC file by someone else. If this fails, use the information provided in the further part of the website.
Unfortunately, if after performing the two previously described steps (trying to find your IPR file converted by someone else, and the attempt to convert it to ARSC on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the IPR file in its original format (without conversion to ARSC file). Such a solution will be difficult to implement, but it certainly will give the best result.
