Turn CAD drawings 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 .dxf file 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.
Converted your DXF 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.
DXF is built for exchange with AutoCAD and engineering tools. FlatGeobuf is built for large datasets and cloud-native web maps.
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.
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 DXF file
DXF files don't record a coordinate system, so you may need to assign the right one after conversion. Text and blocks may not become standard map features.
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 DXF 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 DXF features to OpenLayers or Leaflet without running a map server.
Every converter runs in your browser and keeps your files on your device.
