APK Editor Studio is a free and open-source program that will allow you to easily reverse engineer any APK. This means that you can basically load any Android app in APK format, take a look at its content, work with it, and save any changes you want to make— all this through a very smooth and accessible interface.
Change the name and icon of any app
APK Editor Studio has many interesting features, but the two that stand out the most are pretty useful— they let you change the name and icon of any app. As soon as you load an APK, you'll see two tabs: one with the icon and one with the name. To change the icon, simply import an image, and the program will adapt it automatically, although it's recommended for it to be square and in PNG format. Changing the name is just as easy, and you can also have a different name appear depending on the operating system's language.
Replace the version and modify permissions
Another incredibly useful tool in APK Editor Studio is that you can modify the permissions of any app. It is common to come across apps that, for no apparent good reason, demand more permissions than they should. Thanks to this software, you can remove all these permissions. You can also easily change the version and versionCode of any APK, which is very useful if you want to install or work with older versions of an app.
Enjoy loads of features
In addition to those already mentioned, APK Editor Studio allows you to look at any app's signature, edit an app's manifest or code, change any image within an app, and sign your own apps. If that's not enough, you can also install apps quickly by connecting an Android device to your PC.
An excellent platform for Android developers
Download APK Editor Studio and discover a platform full of possibilities, thanks to which you can edit any APK quickly and easily. This app is particularly useful for developers, but it also has very useful features for anyone who simply wants to tinker around with an APK.

I installed it, but it doesn't open any APK. I mean, when I click OPEN APK, I look for an APK file stored on my PC, and it gives an error on all of them when it can't open it.
