How to Download and Remove Wallpaper from Xiaomi Themes

Xiaomi smartphone owners often face a situation where standard wallpaper is boring, and the Mi Themes store comes across truly unique and beautiful images. However, the standard functionality of the MIUI or HyperOS system does not always allow you to simply save a picture to the gallery. Many users wonder how to download wallpaper from Xiaomi themes without resorting to complex manipulations with root rights.

The problem is that the themes are distributed in a special format called.mtz, which is essentially an archive, and inside this archive, all the resources are hidden: icons, sounds, fonts, and of course, images for the lock screen and desktop, and in order to access these files, you have to open the theme package using specialized tools, which is a safe procedure if you follow proven algorithms of actions.

In this article, we will discuss two main ways to retrieve images: using third-party file managers on the device itself and through the computer, you will learn how to find the right files in the structure of the folders of the system and how to convert them to the usual JPG or PNG format for installation on any other gadget.

Thematics and structure of MIUI files

Before proceeding with extraction, it is important to understand the architecture of the themes in the Xiaomi shell. MIUI. Each topic is not just a picture, but a complex set of topics. XML-files and resources packed in ZIP-It's like a container. When you download a theme from a store, it's stored in a hidden part of your phone's memory, and it reads the data from there in real time, so you can't just see it in a gallery.

Theme files are.mtz. If you downloaded a theme from a third-party source or found a cache on the system, you need to work with this format. Inside the archive, images can be scattered across different folders depending on the type of theme. For example, lock screen wallpaper often lies separate from desktop backgrounds. It is also worth considering that some images can be compressed or have a non-standard resolution adapted to a particular smartphone model.

To work with these files, we need tools that can not only open archives, but also rename extensions, because a standard Android Explorer may not recognize the structure of.mtz as an archive. We will use time-tested utilities that are available in the public domain.

⚠️ Note: When working with system folders, try not to delete the original.mtz files until you are sure that you have successfully saved the desired images. Deleting the theme from the "Themes" menu will automatically clear its cache.

Resource extraction tools required

You'll need a minimum software set to do this, and don't be afraid of the list, because most of these apps are either already installed on your device or are standard utilities for advanced Android users, and the main requirement is that you have internal memory rights.

First of all, you need a file manager with advanced functionality. Xiaomi’s standard Explorer can work with archives, but Total Commander or MT Manager is better for renaming extensions and accessing hidden folders. These applications allow you to see hidden files (starting from a dot) and edit the archive structure.

It is also useful to have an image viewing and editing app on hand to immediately evaluate the quality of the extracted file and crop it if necessary. In some cases, the system gallery may not immediately index new images, so a third-party viewer will be helpful.

• 📂 Total Commander – a powerful file manager for navigating the system.
• 🛠️ MT Manager – a professional tool for working with APK and MTZ files (requires attention).
• 🖼️ QuickPic or analogue – for quick viewing and saving extracted images.

💡

If you are using MT Manager, make sure to download it from an official source, as modified versions may contain malicious code.

Search for folder with downloaded themes on the device

The first step is localizing the theme file. Once you download from the theme store, the file is saved deep in the file system. The path may vary slightly depending on the Android version and the shell, but the logic remains the same. You need to enable the display of hidden files in your file manager settings.

The standard path to the theme storage is MIUI/theme. In the newer versions of HyperOS, the path can be changed to Android/data/com.android.thememanager/files. Inside, you'll see a lot of folders with obscure names consisting of numbers and letters, which are the identifiers of the themes you've installed.

To find the right one, look at the date of the change in files or size. If you just applied a theme, look for the folder with the latest modification time. Inside it often lies a description.xml file, which you open with a text editor, you can see the title of the topic and confirm that this is exactly what you need.

Extracting wallpaper through renaming expansion

The easiest and most secure method that doesn’t require complex code manipulation is to rename the file extension. ZIP-If we change the extension, we can open it like a regular folder and pull out the images.

Copy the theme file (or find it in the download folder if you downloaded it from a third-party source) to a convenient location, such as the root of internal memory. Then rename the file by changing the ending from.mtz to.zip. The system will ask for confirmation of the extension change — agree. Now the archive icon will appear in the place of the file.

Open the archive. You're interested in the image, wallpaper, or lockscreen folders inside. That's where the graphics are stored. Often, files can have strange names, so focus on the file size -- wallpapers usually weigh more than icons.

After extraction, remember to rename the archive back to.mtz if you plan to continue using this theme on your Xiaomi device, otherwise the system will no longer recognize it as a design theme.

Using MT Manager for In-depth Analysis

For users who want to have full control over the content of the theme, the ideal tool is MT Manager. This application allows you to view the resources of the theme without first renaming files, which reduces the risk of error. The interface of the program may seem difficult to a beginner, but for our task, basic functions are enough.

Launch MT Manager and go to the directory where the theme file is located. Click on the.mtz file. The action menu will open where you select "View" (View). You will see the folder structure as a list. The navigation is done by double taping on folders.

Once you find the image you want, click on it and select Extract or Save. The utility will define the format and save the file to the directory you specify, and the advantage of this method is that MT Manager correctly handles internal resource links that can be corrupted by simply renaming it to ZIP.

Solving and working with online topics

Often users find that there is no high-resolution image inside the archive, or it has a strange format, which is due to the optimization of themes for different screens. In some cases, the theme loads the "heavy" wallpaper from the Xiaomi cloud when it first starts, in which case the file in the phone's memory will contain only a stub.

If you find that the file weighs suspiciously little (less) 100 Kb, it's probably not a full topic, it's a link, so try applying the theme, wait for the wallpaper to load onto the lock screen, and then look in the folder. MIUI/theme New files with a lot of weight appearing.

Also, be aware of access rights. Android 11 and above has limited access to the Android/data folder, and it may require special permission or access to storage through the system settings menu.

Alternative methods and online services

If you mess with files on your phone is uncomfortable, there are online Xiaomi theme directories, such as thememirror or specialized forums like 4PDA and XDA. On these resources, enthusiasts often post already unpacked theme resources. You can find the title of the theme in search and download the ready JPG file.

Another simple, but less high-quality way is to take a screenshot of a lock screen or desktop, but the quality will depend on your screen resolution, and interface elements (watches, widgets) can overlap part of the image. You can use the built-in gallery editor or Google Photos app to crop the screenshots.

While using wallpaper for personal use is generally not in violation of the rules, the distribution of modified themes or the commercial use of authors' resources may be prohibited.

⚠️ Note: Be careful when downloading themes from dubious sites..mtz files may contain malicious code if they have been modified by third parties.
