Turn MapInfo tables into a fast, streamable FlatGeobuf file. Free, private and processed right in your browser.
Three steps, no software to install. Works on Windows, macOS, Linux and mobile.
01
Drop a .zip with .tab, .dat, .map and .id files into the converter, or click to browse. Files up to 100 MB are supported.
02
Click Convert to FlatGeobuf. The file is processed locally, so your data is never uploaded to a server.
03
The FlatGeobuf file downloads straight to your device. Need another format? Pick a converter below.

Publish a read-only map, embed it on your site, or keep it private with role-based access.
No credit card. No GIS degree. Upload your data and start mapping in minutes.
MapInfo TAB is built for working in MapInfo Pro. FlatGeobuf is built for large datasets and cloud-native web maps.
MapInfo TAB
MapInfo TAB is the native format of MapInfo Pro. A table is a set of files — .tab (structure), .dat (attributes), .map (geometry) and .id (index) — that must travel together.
It remains common in telecom, insurance, retail and public-sector teams that have worked with MapInfo for years.
FlatGeobuf
FlatGeobuf is an open, binary vector format built on FlatBuffers. It stores features with a built-in spatial index, so software can read just the area it needs.
It is one of the fastest formats to read and write, and it can be streamed over HTTP from cloud storage without a map server.
Your MapInfo TAB file
Upload all MapInfo files together (.tab, .dat, .map, .id) in one .zip, or the geometry can't be read.
The FlatGeobuf output
The output includes a spatial index, so it is ready for fast bounding-box reads and streaming.
Your file never leaves your device: conversion runs in your browser, for files up to 100 MB.
Open large MapInfo TAB datasets in seconds instead of minutes.
Host the file on S3 or any static storage and read only the visible map area over HTTP.
Serve MapInfo TAB features to OpenLayers or Leaflet without running a map server.
Every converter runs in your browser and keeps your files on your device.
