To convert other file formats to the "Print Job / XML Metadata" file type, you need software like ONYX Thrive or a similar tool.
About ONX files
The .ONX file extension generally represents an ONYX RIP print job created by ONYX Graphics software. It stores rasterized image data, layout settings, scaling instructions, and color profiles optimized for wide-format industrial printers. Less commonly, it functions as an ONIX for Books metadata file. This is an XML-based standard developed by EDItEUR to share book catalog information - such as ISBNs, authors, pricing, and availability - between publishers and online retailers.
Users often face severe challenges with .ONX files. As a print job, the format is highly proprietary, closed, and heavily compressed. It is engineered for machine hardware, meaning files frequently exceed 1GB and cannot be opened by standard image editors like Adobe Photoshop or standard web browsers. Extracting the original vector or high-resolution raster image from an ONYX print job is practically impossible because the data has already been translated into hardware-specific dot patterns. For the book metadata variant, users often need to convert the XML structure into a spreadsheet format to review catalog data.
For the ONIX book metadata variant, converting to XML, TXT, or CSV is the best target to make the data readable in standard spreadsheet applications. For the print job variant, standard online converters fail because the file contains proprietary machine code rather than standard pixels or vectors.
This file format is difficult to open or convert, and often only the original software can properly read or export the data. However, just drag and drop your file onto convert.guru to identify the format, view it, and convert it when possible. If our analysis detects the ONIX book metadata variant, viewing or conversion to text is immediate. For print jobs, if we detect supported embedded previews, partial viewing may still be possible.
Convert.Guru analyzes your ONX file, detects the exact format, and lets you read the text inside.

The ONX 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 ONX converter.
