Turn GeoJSON features into a single-file GeoPackage. Free, private and processed right in your browser.
Three steps, no software to install. Works on Windows, macOS, Linux and mobile.
01
Drop a .geojson or .json file into the converter, or click to browse. Files up to 100 MB are supported.
02
Click Convert to GeoPackage. The file is processed locally, so your data is never uploaded to a server.
03
The GeoPackage file downloads straight to your device. Need another format? Pick a converter below.
Converted your GeoJSON 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.
GeoJSON is built for web maps, APIs and JavaScript apps. GeoPackage is built for modern desktop GIS and multi-layer projects.
GeoJSON
GeoJSON is an open standard (RFC 7946) for describing geographic features in JSON. Each feature pairs a geometry — point, line or polygon — with a set of properties.
It is the native format of web mapping libraries like Leaflet, Mapbox GL and OpenLayers, and of most geospatial APIs. The trade-off: plain text gets heavy for large datasets.
GeoPackage
GeoPackage is an open OGC standard built on SQLite. One .gpkg file can hold many vector layers, raster tiles and attribute tables together.
It has none of the Shapefile's limits — long field names, large files, proper data types — and it is the default format in QGIS.
Your GeoJSON file
GeoJSON coordinates are expected in WGS84 longitude/latitude, as the standard requires.
The GeoPackage output
Field names and data types are kept as they are — there is no 10-character limit.
Your file never leaves your device: conversion runs in your browser, for files up to 100 MB.
Bundle GeoJSON data into one portable file instead of folders of sidecar files.
Both read GeoPackage natively, with field names and types intact.
Edit the converted GeoJSON data offline in mobile apps like QField and Mergin Maps.
Every converter runs in your browser and keeps your files on your device.
