Extract text from OziExplorer tiled maps (OZFX3)
To convert OZFX3 tiled maps to another format, you need OziExplorer or other GIS software.
To convert other file formats to the "Proprietary Tiled Map" file type, you need software like OziExplorer or a similar tool.
The .ozfx3 file is a tiled map image format created specifically for OziExplorer GPS mapping software. It stores large topographic maps as compressed image tiles, allowing older or low-power GPS devices to pan and zoom quickly without loading the entire raster map into memory.
To use this file natively, you need the official desktop or mobile version of OziExplorer. The format is heavily dependent on a companion MAP file, which stores the essential spatial calibration and coordinate system data required to align the image with GPS coordinates.
Users frequently struggle with the .ozfx3 format because it is highly proprietary and severely restricts how you can use your own map data. Standard image editors like Adobe Photoshop and web browsers cannot read it. You are effectively locked into a single software ecosystem, making it frustrating if you want to share maps or view them on modern GIS platforms.
Most users look to convert .ozfx3 files to universal formats like PNG, JPG, or .GeoTIFF. Converting to .GeoTIFF is highly recommended because it preserves the geographic calibration data, whereas standard raster formats will strip away all spatial intelligence and leave you with a dumb image.
This file format is notoriously difficult to open or convert because the developers deliberately closed the ecosystem to prevent third-party usage. Standard online converters fail completely because the internal tiling and compression algorithms are undocumented. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your OZFX3 file, detects the exact format, and lets you read the text inside.
Users also converted MAP, OZF2, HMR and MMI files.
If you want to convert OZFX3 file to , you can use OziExplorer or similar software from the "Tiled Map Image Storage" category. In the File menu, look for Save As… or Export….
To convert files to OZFX3, try OziExplorer or another comparable tool in the "Tiled Map Image Storage" 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 OZFX3 converter.
