GeoUnpackDrop an Esri package or a zipped file geodatabase below. GeoUnpack lists every layer, previews it on a map, and exports it to the format you need. All inside your browser.
What these Esri files are
Layer packages (.lpk, .lpkx) and map packages (.mpk, .mpkx) are 7-Zip archives made by ArcMap or ArcGIS Pro. Inside is a layer or map definition plus a copy of the data, almost always a file geodatabase (.gdb) and sometimes shapefiles. A file geodatabase is a folder of binary tables that ArcGIS uses as its native storage.
The data itself is not locked to ArcGIS. The open-source GDAL library reads file geodatabases directly, and GeoUnpack runs GDAL inside your browser, so you get the same result as the command-line route without installing anything.
What you get, and what you don't
GeoUnpack extracts the data, not the map design.
- Kept: geometry, all attribute fields, the coordinate system, standalone tables.
- Not kept: symbology, labels, layouts, definition queries and joins. Those live in the layer or map definition, which only ArcGIS can render.
- Not read yet: raster, tile and scene data, and packages that only reference data on a server instead of containing it.
Which output format to pick
GeoPackage is the safest choice for QGIS and most modern GIS software: one file, long field names, no size cap. Choose Shapefile when the receiving software only accepts it, GeoJSON for web maps and code, KML for Google Earth, and CSV when you only need the attribute table in a spreadsheet.
How to use it
- Drop your .lpk, .lpkx, .mpk, .mpkx or zipped .gdb file into the box.
- Check the layers you want. Click Preview to see a layer on the map.
- Pick an output format and click Convert & download.
Supported formats
| Input | What it is |
|---|---|
.lpk / .lpkx | ArcGIS layer package (ArcMap / ArcGIS Pro) |
.mpk / .mpkx | ArcGIS map package (ArcMap / ArcGIS Pro) |
.gdb (zipped) | File geodatabase folder, compressed to .zip |
Output: Shapefile, GeoPackage, GeoJSON, KML, CSV. Vector layers and tables only; raster and tile packages are not supported yet.
FAQ
Is my file uploaded to a server?
No. GeoUnpack runs the open-source GDAL and 7-Zip libraries inside your browser using WebAssembly. Your file never leaves your computer.
Which files can I open?
ArcGIS layer packages (.lpk, .lpkx), map packages (.mpk, .mpkx) and file geodatabases (.gdb folders compressed as .zip). Vector layers and attribute tables are supported. Raster, tile and scene packages are not supported yet.
Do I need ArcGIS or QGIS?
No. You only need a modern browser such as Chrome, Edge, Firefox or Safari on a computer.
Is there a size limit?
Files up to 150 MB are supported for now, because everything runs in your browser's memory.
