Turn FlatGeobuf datasets into a SQLite database you can query with SQL. Free, private and processed right in your browser.
Three steps, no software to install. Works on Windows, macOS, Linux and mobile.
01
Drop a .fgb file into the converter, or click to browse. Files up to 100 MB are supported.
02
Click Convert to SQLite. The file is processed locally, so your data is never uploaded to a server.
03
The SQLite file downloads straight to your device. Need another format? Pick a converter below.
Converted your FlatGeobuf file? Upload it to GISCARTA and turn it into an interactive map your team or clients can actually use.
Colour by attribute, cluster thousands of points, switch on 3D.
Charts and key numbers next to the map, updated as you filter.
Animate dated features and compare how places change.
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.
FlatGeobuf is built for large datasets and cloud-native web maps. SQLite is built for SQL querying and mobile or offline apps.
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.
SQLite
SQLite is a self-contained, serverless SQL database stored in a single file. Each layer sits in its own table, and you can filter, aggregate and join it with standard SQL.
With the SpatiaLite extension, SQLite also stores geometry and supports spatial queries. It opens in QGIS, DB Browser for SQLite, Python, R and many mobile and desktop apps.
Your FlatGeobuf file
A FlatGeobuf file holds one layer.
The SQLite output
Each layer becomes its own table, with geometry stored next to the attribute columns.
Your file never leaves your device: conversion runs in your browser, for files up to 100 MB.
Filter, aggregate and join FlatGeobuf data with standard SQL instead of scrolling through files.
Embed the FlatGeobuf data in mobile and offline apps that already use SQLite.
Read the tables directly with sqlite3, pandas or R's DBI.
Every converter runs in your browser and keeps your files on your device.
