Convert WER to another file type
To convert WER error reports to another format, you need Windows Error Reporting or other System software.
Convert a file to WER
To convert other file formats to the "Diagnostic Log File" file type, you need software like Windows Error Reporting or a similar tool.
About WER files
The .WER file format is a diagnostic text log generated by the Microsoft Windows operating system. When a program crashes, hangs, or encounters a fatal fault, the Windows Error Reporting (WER) service automatically compiles a report containing crash data, such as the application name, version, faulting module, exception codes, and timestamp. These files are typically stored in the hidden ProgramData or user AppData directories. Because these files are system-generated and contain raw telemetry data encoded in UTF-16 (LE), they are not designed for everyday user interaction. A major disadvantage is that they accumulate over time, consuming gigabytes of disk space on system drives if left unchecked. Users usually encounter these files when troubleshooting software bugs or performing disk cleanups. Furthermore, while the files are technically plain text, the formatting is dense and difficult for non-technical users to interpret without specialized debugging tools. Converting a .WER file to a standard TXT or PDF is highly recommended if you need to share crash logs with a technical support team or developer. You might also convert them to XML or CSV for bulk log analysis. Converting these files preserves the textual crash data but makes it universally readable across non-Windows platforms like macOS and Linux. System log files are often locked by the operating system or tightly integrated into Microsoft telemetry infrastructure, which makes direct conversion with standard online tools frustrating. Just drag and drop your file to identify the format, view it, and convert it when possible using convert.guru. Even if it is a system-specific format, convert.guru can inspect the .WER file, extract the readable UTF-16 text, and help you view or export the underlying diagnostic data safely.
Convert.Guru analyzes your WER file, detects the exact format, and lets you read the text inside.
If you want to convert WER file to SYS, DLL, EXE, DRV, VXD, 386, COM, BAT, CMD, SCR, PIF or LNK, you can use Windows Error Reporting or similar software from the "Error Logging and Diagnostics" category. In the File menu, look for Save As… or Export….
To convert MSI, EXE, REG, MST, LNK, CAB, CAT, DRV, INF, SYS, MSU or DLL files to WER, try Windows Error Reporting or another comparable tool in the "Error Logging and Diagnostics" category.
The WER Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WER converter.
