About HDMP files
An .HDMP file is an uncompressed Windows Heap Dump generated by the Microsoft Windows Error Reporting (WER) system. These files are massive forensic snapshots - often exceeding 500MB - captured when an application like Google Chrome or a system service crashes. Unlike standard documents, an .HDMP file contains raw binary memory data, making it impossible to open in text editors like Notepad++ or Microsoft Word. Because they record the exact state of the computer's memory at the moment of failure, they are critical for developers but dead weight for average users. To "convert" this file usually means analyzing it with a debugger to export a human-readable TXT log of the crash stack, or compressing it into a standard MDMP (Minidump) to share with support teams without hitting email attachment limits.
Convert.Guru analyzes your HDMP file, detects the exact format, and lets you read the text inside.
If you want to convert HDMP file to SYS, DLL, EXE, DRV, VXD, 386, COM, BAT, CMD, SCR, PIF or LNK, you can use WinDbg or similar software from the "Crash Memory Snapshot" 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 HDMP, try WinDbg or another comparable tool in the "Crash Memory Snapshot" category.
The HDMP 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 HDMP converter.
