Convert E00 to GDB Online - Free & Fast

What is E00?

ArcInfo Exchange (E00) is a proprietary interchange format developed by ESRI for exporting and importing Arc/Info coverages, encoding vector topology, attributes, and raster data in an ASCII text file for data migration between GIS systems.

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.

When Should You Use E00 vs GDB?

E00 vs GDB: Key Differences

• •E00 uses lossy compression while GDB uses lossless compression — this is the fundamental technical difference between the two formats.
• •Moving from E00 (lossless) to GDB (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: GDB supports transparency, so alpha information is preserved during conversion.
• •E00 files are typically 100KB to several GB depending on coverage complexity while GDB files range 1MB to 1TB+ depending on data volume
• •E00 is optimized for legacy arcinfo data migration, gis archival data recovery while GDB is designed for enterprise gis data management, esri ecosystem spatial storage — choose based on your specific workflow needs

Advantages of E00

• ✓E00 compresses data using lossy methods, keeping file sizes manageable for Legacy ArcInfo data migration, GIS archival data recovery.
• ✓Industry-wide support means E00 files open anywhere — from legacy systems to the latest devices.
• ✓Small file sizes make E00 ideal for email, web uploads, and cloud storage.
• ✓From professional software to open-source alternatives, E00 works out of the box.

Advantages of GDB

• ✓GDB compresses data using lossless methods, keeping file sizes manageable for Enterprise GIS data management, ESRI ecosystem spatial storage.
• ✓Industry-wide support means GDB files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes GDB the gold standard for archival and master copies.
• ✓From professional software to open-source alternatives, GDB works out of the box.

Common Use Cases for E00 to GDB Conversion

Industry Applications

Best Practices for E00 to GDB Conversion

• →When converting E00 to GDB: confirm the coordinate reference system (CRS / projection) is preserved or explicitly reprojected
• →Keep attribute tables and feature metadata intact — GDB should retain all fields from E00
• →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 E00 to GDB Conversion

• !Topology errors in the converted GDB → self-intersecting polygons or duplicate vertices may not transfer cleanly between formats
• !The GDB file coordinate values shifted slightly → datums (WGS84 vs NAD83) differ even when the projection looks similar
• !Time field values were corrupted after converting E00 to GDB → date and time field formatting varies across GIS formats
• !Null geometry features appear in the converted GDB → empty or null-shape records in E00 may cause validation errors in some formats
