What is a WPB file?
A .WPB file can be one of two distinct formats. Most commonly, it is an openCanvas 1.1 Image file. Created by Portalgraphics, openCanvas is a popular raster graphics software used for digital art. In its early freeware versions, specifically version 1.1, the software saved artwork using the .WPB file extension. Later versions of the software transitioned to the .OCI format.
Alternatively, a .WPB file can be a Windows Phone Device Manager Backup File. These files were created by third-party management utilities to back up applications, contacts, text messages, and configurations from older Windows Phone mobile devices.
How to open WPB files?
If your file is an openCanvas 1.1 Image, you can try opening it using legacy versions of openCanvas. However, modern graphics programs may struggle with these older .WPB project files. If the file is a Windows Phone Device Manager Backup File, you would need the original, now-obsolete Windows Phone management software and its dependencies to fully restore the archive.
Because .WPB has multiple possible meanings and relies on older software, opening these files on a modern operating system can be difficult. If you are unsure what your file contains, we recommend using viewer.online/wpb to identify the actual format.
Best practices and tools
The first step when encountering an unknown .WPB file is identifying its true format. viewer.online/wpb can analyze .WPB files to identify the exact format and creator software, inspect the internal file structure, extract readable text, and check whether an online preview is available.
Summary
Whether you are trying to view old digital art or inspect an archived mobile phone backup, viewer.online/wpb is useful for identifying, inspecting, and understanding .WPB files without installing software or dealing with compatibility problems.
