Convert DGN to GPKG Online - Free & Fast

What is DGN?

DGN (Design) is the native file format of Bentley Systems MicroStation, used for storing CAD drawings and GIS data in infrastructure projects such as roads, bridges, and utilities, supporting 2D and 3D design elements with level-based organization.

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 DGN vs GPKG?

DGN vs GPKG: Key Differences

• •DGN and GPKG diverge on compression: lossy compression for the source, lossless compression for the target.
• •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
• •Alpha channel support: GPKG lacks transparency support.
• •File sizes: DGN files typically range 100KB to 1GB depending on design complexity and GPKG files 10KB to several GB depending on feature density.
• •Primary audience: DGN is built for civil engineering, infrastructure mapping, transportation gis scenarios, while GPKG focuses on mobile gis, offline mapping, portable geospatial data exchange — pick the format that matches your output requirement.

Advantages of DGN

• ✓DGN compresses data using lossy methods, keeping file sizes manageable for Civil engineering, infrastructure mapping, transportation GIS.
• ✓Industry-wide support means DGN files open anywhere — from legacy systems to the latest devices.
• ✓Small file sizes make DGN ideal for email, web uploads, and cloud storage.
• ✓From professional software to open-source alternatives, DGN works out of the box.

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 DGN to GPKG Conversion

Industry Applications

Best Practices for DGN to GPKG Conversion

• →When converting DGN 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 DGN
• →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 DGN to GPKG Conversion

• !GPKG features land in the wrong place after DGN 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
• !DGN 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
