Convert GDB to GPKG Online - Free & Fast

What is GDB?

ESRI File Geodatabase (GDB) is a collection of files in a folder structure that stores vector feature classes, raster datasets, topology rules, and network datasets, serving as the primary geospatial data storage format in ArcGIS.

What is GPKG?

GeoPackage (GPKG) is an open, standards-based, portable SQLite format for storing vector features, tiled map overlays, and attribute data in a single file, designed as a modern replacement for the Shapefile by the Open Geospatial Consortium.

When Should You Use GDB vs GPKG?

GDB vs GPKG: Key Differences

• •The core technical difference: GDB relies on lossless compression whereas GPKG uses lossless compression.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Transparency: N/A - SQLite binary format
• •GDB files are typically 1MB to 1TB+ depending on data volume while GPKG files range 10KB to several GB depending on feature density
• •Primary audience: GDB is built for enterprise gis data management, esri ecosystem spatial storage scenarios, while GPKG focuses on mobile gis, offline mapping, portable geospatial data exchange — pick the format that matches your output requirement.

Advantages of GDB

• ✓GDB uses lossless compression tailored for Enterprise GIS data management, ESRI ecosystem spatial storage.
• ✓GDB is supported natively on virtually every device, browser, and operating system.
• ✓GDB files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓GDB integrates seamlessly with all major creative tools and workflows.

Advantages of GPKG

• ✓At its core, GPKG relies on lossless encoding — a design choice that makes it perfect for Mobile GIS, offline mapping, portable geospatial data exchange.
• ✓You won't run into compatibility issues with GPKG — it's a universal standard across platforms.
• ✓File size management with GPKG: larger files guaranteed to match the original exactly.
• ✓Every major application in the Mobile GIS, offline mapping, portable geospatial data exchange space supports GPKG natively.

Common Use Cases for GDB to GPKG Conversion

Industry Applications

Best Practices for GDB to GPKG Conversion

• →When converting GDB to GPKG: confirm the coordinate reference system (CRS / projection) is preserved or explicitly reprojected
• →Keep attribute tables and feature metadata intact — GPKG should retain all fields from GDB
• →Check geometry types (point, line, polygon) map cleanly between the two formats
• →Verify that z/elevation values and topology survive the conversion when working with terrain data
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting GDB to GPKG Conversion

• !GPKG features land in the wrong place after GDB to GPKG → verify the CRS/projection; mismatched coordinate systems shift geometry
• !Attribute columns missing in GPKG → some GIS formats have field name length or type limits; rename or cast columns first
• !GDB to GPKG drops the z/elevation dimension → pick a target format that supports 3D geometry
• !GPKG file won't open in your GIS app → confirm the format version and any required sidecar files (e.g. .prj, .shx) are present
