APPX packages are apps for Windows Phone 8.1 and later, whilst XAP packages were used up until Windows Phone 8. It is extremely unlikely that some way how one could be converted to another (in this case APPX to XAP) exists, or vice versa. That's something the developer of the app could do if he would release two versions for both Windows Phone 8 and 8.1.
Simply put, it is impossible to convert APPX to XAP directly.
Thus, there is no so-called appx to xap converter or a free online .appx to .xap conversion tool.

Understanding APPX and XAP file formats
APPX is a file format used by Microsoft for packaging and distributing applications on Windows 8 and later versions. It is a modern format that supports a wide range of features, including security and deployment enhancements. XAP, on the other hand, is an older file format used for packaging applications for Windows Phone 7 and Silverlight applications. It is less advanced compared to APPX and is primarily used for legacy applications.
Why convert APPX to XAP?
Converting APPX to XAP might be necessary if you need to deploy an application on older Windows Phone devices that do not support the APPX format. This conversion allows developers to maintain compatibility with legacy systems.
Best software for APPX to XAP conversion
Converting APPX to XAP is not a straightforward process due to the differences in the formats. However, developers can use tools like Visual Studio to manually adjust and repackage the application. Here’s a general approach:
- Open your APPX project in Visual Studio.
- Modify the project settings to target Windows Phone 7.
- Use File → Export to create a new project compatible with XAP.
- Rebuild the project to generate the XAP file.
Note that this process may require significant adjustments to the code and resources to ensure compatibility with the older platform.
