About AUX files

The .AUX extension primarily identifies an Auxiliary File generated by the LaTeX typesetting system. These files act as the backbone for document structure, storing crucial cross-reference data like chapter labels, bibliography keys, and citation markers created during the compilation of a TEX source file. A significant limitation of the .AUX format is that it is not a standalone document; users often attempt to convert it to PDF expecting a readable paper, but the file contains only plaintext metadata and internal pointers. Because it is generated automatically, it can be deleted and recreated by recompiling the source, yet missing it can cause reference errors like "??" in your final output.

Another prominent use is within Geographic Information Systems (GIS), specifically software like ERDAS IMAGINE by Hexagon. In this context, the .AUX file is a binary or XML-based sidecar that stores statistical data, coordinate system information, and pointers for a larger raster image file. The friction here is dependency: transferring a heavy raster map without its lightweight .AUX companion strips it of its geospatial intelligence.

Conversion Recommendations:

For Inspection & Debugging: Convert .AUX to TXT or view directly in a browser to check for corrupted citation keys or log errors.
For Document Recovery: If you only have the .AUX, you cannot regenerate the full document. You must locate the original TEX file to produce a PDF.
For GIS Data: Ensure the .AUX remains in the same directory as its parent raster file. Converting these to XML can help in auditing metadata without opening heavy GIS suites.

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

Users also converted XML, RRD, OVL, ZIP, TEX, PDF, BNK, TFW, TXT, SDOCX, EFT, CHI and XFT files.

The AUX 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 AUX converter.
