Convert JDBG to another file type

To convert JDBG Symbols to another format, you need JEDI Code Library or other Developer software.

Convert a file to JDBG

To convert other file formats to the "Debug Symbol File" file type, you need software like JEDI Code Library or a similar tool.

About JDBG files

A .jdbg file is primarily a JEDI Code Library Debug file, a binary format used by developers working with Embarcadero Delphi and C++Builder. These files act as a compressed, secure alternative to standard MAP files, storing critical debugging data - such as line numbers, procedure names, and source code locations - in a compact binary blob (typically ~12% the size of a MAP file).

Users often encounter .jdbg files when analyzing crash dumps or setting up error reporting systems for Windows applications. A common issue is that .jdbg files are not human-readable; opening them in a text editor reveals garbled binary code. They are designed to be read programmatically by the application itself (via the JclDebug unit) to generate readable stack traces during runtime errors.

Best Conversion Targets:

To Text (.TXT/.LOG): The most common goal is not to convert the file itself, but to use it to generate a human-readable stack trace or crash log. This is done by ensuring the .jdbg file resides in the same directory as the executable during a crash.
To .MAP: While .jdbg is created from a MAP file using the MapToJdbg tool, converting it back is difficult without the original build artifacts.
To Hex Dump: For manual inspection of headers or checksums, viewing as a Hex dump is the only direct "conversion" available without the parent application.

Convert.Guru analyzes your JDBG file, detects the exact format, and lets you read the text inside.

Users also converted DCR, RSM and DPR files.

The JDBG 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 JDBG converter.
