Turn FlatGeobuf datasets into a DXF drawing for AutoCAD and other CAD tools. 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 DXF. The file is processed locally, so your data is never uploaded to a server.
03
The DXF 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. DXF is built for exchange with AutoCAD and engineering tools.
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.
DXF
DXF (Drawing Exchange Format) is Autodesk's open format for sharing CAD drawings, introduced with AutoCAD in 1982. It stores lines, polylines, arcs, text and blocks organised in layers.
DXF is the bridge between GIS and engineering teams. It carries geometry well, but attribute tables and coordinate system information are usually lost or limited.
Your FlatGeobuf file
A FlatGeobuf file holds one layer.
The DXF output
DXF keeps geometry and layers but drops most attribute data — keep the original file if you need the attribute table.
Your file never leaves your device: conversion runs in your browser, for files up to 100 MB.
Give architects and civil engineers FlatGeobuf data as a drawing they can open in AutoCAD.
Use FlatGeobuf parcels, roads or utilities as a base layer for design drawings.
Bring FlatGeobuf boundaries and survey points into BricsCAD, MicroStation or LibreCAD.
Every converter runs in your browser and keeps your files on your device.
