How to open MapInfo online

View MapInfo TAB and MIF/MID files. Upload .tab or .mif files (along with their sidecars like .dat, .id, .map).

Privacy

Files are processed on your device in the browser. GeoDataViewer does not upload your datasets to a server for viewing.

Common issues

If a dataset uses multiple required sidecar files, make sure you provide the complete set together. For best results, keep all sidecars in one zip archive when applicable.

What is MapInfo?

MapInfo datasets are vector exchange formats tied to the MapInfo Pro ecosystem and are still common in business mapping, utilities, and long-running desktop GIS environments.

In practice, MapInfo workflows usually revolve around TAB-based datasets or MIF/MID pairs, often with sidecar files that together describe geometry, attributes, and table structure.
The format remains important where organizations have established MapInfo tooling, but many cross-platform teams convert it into more neutral or web-friendly outputs for wider distribution.

What is MapInfo used for?

  • Exchanging vector data with teams and systems that use MapInfo Pro.
  • Supporting business mapping, retail analytics, utilities, and location intelligence workflows with legacy MapInfo roots.
  • Preserving compatibility with existing desktop projects that expect TAB or MIF/MID datasets.

Common use cases

  • Customer, territory, trade-area, and service-network mapping in established MapInfo environments.
  • Vendor or client deliveries where recipients still standardize on TAB datasets.
  • Converting older business mapping assets into modern GIS or web-friendly formats.

Strengths

  • Strong compatibility with MapInfo-centered desktop workflows.
  • Familiar exchange format in long-running business mapping environments.
  • Useful when recipients explicitly expect TAB or MIF/MID structures.

Limitations

  • Multi-file packaging can be fragile during manual transfer and archiving.
  • Modern cloud, browser, and open interchange workflows often prefer more neutral formats.
  • Many non-MapInfo users are less familiar with its sidecar structure.

File extensions and sidecar files

.tab
Main MapInfo table definition file that references the other sidecar components.
.dat
Attribute storage sidecar used with TAB datasets.
.map
Spatial storage sidecar containing geometry information.
.id
Index sidecar used by TAB datasets.
.mif / .mid
Alternate MapInfo interchange pair where .mif carries structure and geometry while .mid carries attributes.

MapInfo Viewer FAQ

What is the difference between TAB and MIF/MID?

TAB is the more common MapInfo dataset family with several sidecars, while MIF and MID split geometry structure and attributes into an interchange pair.

Why do MapInfo datasets often travel as bundles?

The complete dataset is spread across multiple files, so moving only one file usually breaks the layer.

Why convert MapInfo to GeoPackage or GeoJSON?

Those formats are easier to share across mixed GIS stacks and are more practical for modern web, API, and archival workflows.
