Apple delivers the macOS installer and applications through the app store since the launch of OS X Lion. The macOS installer has a .app extension when you get it through the official channel. Unlike the macOS DMG installer, which Apple doesn’t provide nowadays, the app version of the macOS install package is not bootable. Hence it is not mountable nor compatible with operating systems like Windows. For some reason, if you want macOS in .DMG or .ISO format, there is a method to convert the .app file. Unfortunately you need a macOS system to convert .app to .dmg to .iso image.
A DMG disk image file is Apple's container format for capturing entire drives or disks, similar to ISO for other platforms like Windows. It consists of data blocks that represent a physical disc. If you're on a Windows machine, you're limited in what you can do with DMG files. Since ISO is a better format for Windows, you can also convert the DMG to the ISO format and then use the ISO disk image to create the bootable USB. Please note that you can't boot your Mac from bootable USB made from an ISO file, which means you'll have to convert it back to DMG prior to that.

Above all, DMG and ISO files are highly portable; it is easy for anyone to upload and transfer them through the Internet.
The requirement for running macOS, and a USB Pen Drive for converting the Installer application to bootable ISO or DMG image. The step by step process for converting macOS Mojave, High Sierra, Sierra, EI Capitan to the bootable .DMG or .ISO is explained below.

There are several ways to convert macOS .app to .ISO bootable image. Usually one need to do APP to DMG or CDR conversion before making it an ISO file on Mac. The Disk Utility app in macOS previously had an option that allows you to convert DMG to ISO/CDR. You can use Terminal and third-party apps to convert Mac OS installer to ISO if it is in CDR format.
AnyToISO app capable of converting macOS DMG to iso format. The free version of AnyToISO doesn’t support converting dmg files above 850 MB. Hence, you need to either purchase or download (Search AnyToISO Pro 3.9.0 in Google) the PRO version of this app.
In my experience, converting DMG to ISO with AnytoISO takes a lot of space and resources if you’re on macOS machine. The system shows out of space notification even though you have enough space left in the disk. Therefore, it is better to transfer the DMG files to a Windows machine and use freeware like DMGtoISO or AnyBurn for converting.
