Are you trying to from an existing Samsung firmware, or are you trying to create a custom boot animation ?
In the context of Android customization, Samsung devices utilize a specific file architecture for their Theme Store. Unlike standard Android APKs or standard image formats (PNG/JPG), Samsung packages theme data into .qmg files. Because this format is proprietary and not natively supported by standard image viewers or the Android operating system's core media framework, a specialized "QMG Viewer" is required by developers and themers to reverse-engineer or extract these assets.
files. These aren't your typical JPEGs or PNGs—they are specialized containers used for boot animations and system themes. What is a QMG Viewer?
, which are proprietary graphic and animation files primarily developed by Samsung Electronics. These files are core components of Samsung’s Android themes and system animations, such as the logos seen during device startup or shutdown. Core Functionality of QMG Files QMG files (short for Qmage Encoded Data qmg viewer

Using a QMG Viewer is not always straightforward:
shutdown.qmg : The animation displayed when the device powers off. Are you trying to from an existing Samsung
For developers, system administrators, or power users who need to work with QMG files programmatically or in bulk, and custom scripts offer the most flexibility. These solutions often provide the ability to convert multiple QMG files to PNG at once, which can be a massive time-saver.
Because standard image viewers cannot read QMG files, converting them to PNG is the easiest way to view them. Follow these steps using the community-favorite tool:
If you have ever dug into the internal filesystem of a Samsung Galaxy smartphone or tried to build a custom Android ROM, you have likely run into files with the extension. Unlike standard image formats like PNG or JPEG, double-clicking a QMG file on a computer usually results in an error. Because this format is proprietary and not natively
: This Windows-based application allows developers to compile image assets into .SMT theme files, which contain packaged QMG files and structural XML code.
The QMG Viewer is a powerful tool that has revolutionized the field of medical imaging. With its advanced features, customizable interface, and wide range of applications, the QMG Viewer has become an indispensable asset for healthcare professionals, researchers, and organizations. As medical imaging continues to evolve, the QMG Viewer is poised to play a leading role in shaping the future of medical imaging and diagnostics.
Because QMG is a closed-source, highly proprietary format, it features unique byte headers and compression matrices that standard image libraries (like GDI+ or standard OpenGL textures) do not recognize.

To successfully view what is inside a QMG file, you have to use specific legacy developer kits, custom community conversion scripts, or device-rooted workflows. Best Methods to View and Open QMG Files
