Extract text from Gravograph engraving jobs (GNH)
To convert GNH Engraving jobs to another format, you need Gravostyle or other Cad software.
To convert other file formats to the "Engraving Job File" file type, you need software like Gravostyle or a similar tool.
A .GNH file is a proprietary engraving job file used by Gravotech Gravostyle software. It contains exact toolpaths, layout designs, and machine instructions tailored specifically for Gravograph New Hermes rotary and laser engravers. These files hold not just vector graphics, but machine-specific parameters like spindle speed, engraving depth, and tool type.
The primary disadvantage of the .GNH format is its highly restrictive, closed nature. It requires an expensive, hardware-locked software license to open. You cannot view or edit these files in standard design applications like Adobe Illustrator or AutoCAD. This vendor lock-in creates major bottlenecks if a business attempts to migrate to a different CNC or laser cutting platform.
To archive designs or share them with third-party manufacturers, users desperately need to convert .GNH files to universal vector formats like DXF, SVG, or PDF. However, standard online converters consistently fail because the format is heavily encrypted or proprietary. Often, only the original Gravostyle software can properly read or export the path data to an open format.
Despite these limitations, you are not entirely stuck. We can extract readable text, view internal data headers, and if our analysis detects a supported underlying or embedded vector format, viewing or conversion to SVG or DXF may still be possible.
Convert.Guru analyzes your GNH file, detects the exact format, and lets you read the text inside.
Users also converted VNM, JPG, SVG, JPEG, ZIP, PNG, BAK and PDF files.
If you want to convert GNH file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Gravostyle or similar software from the "Engraving Job Configuration" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to GNH, try Gravostyle or another comparable tool in the "Engraving Job Configuration" category.
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 GNH converter.
