About MapInfo TAB
MapInfo TAB format is the native format of MapInfo Pro, an enterprise desktop GIS application widely used in telecommunications, utilities, and government mapping. A MapInfo TAB dataset consists of multiple companion files (.tab, .dat, .map, .id) typically distributed as a ZIP archive.
You might convert from MapInfo TAB when migrating a legacy GIS workflow to modern formats, when sharing data with colleagues who use open-source GIS tools that prefer GeoJSON or GeoPackage, or when importing the data into a web mapping platform that does not support the format.
Frequently asked questions
Do I need to upload all MapInfo TAB files?
Upload the files as a single ZIP archive containing at minimum the .tab, .dat, .map, and .id files. Including the .prj file ensures the coordinate reference system is correctly interpreted.
What is the difference between TAB and MIF/MID format?
TAB is MapInfo's binary format; MIF/MID is its ASCII export format. Both are supported — upload either as a ZIP archive containing all companion files.
Can I convert a MapInfo TAB file with a non-standard CRS?
Yes — if the .prj file is present, the CRS is read automatically. If not, the converter will attempt to interpret the coordinates but the output may need manual CRS assignment using the Assign CRS tool.
Only have one file?
Our single-file MapInfo TAB to GeoJSON converter is free and handles one file at a time.
