WKT to GeoPackage Converter
Convert text-geometry strings into SQLite database layers.
This tool is designed to parse WKT (Well-Known Text) geometry text and save it to a portable SQLite-based GeoPackage database, complete with spatial indexing options.
Drag file here to convert, or select file
Supported file extension: .wkt, .txt • Max 50MB
Specification Rules
- Convert text coordinates into GIS databases
- Consolidate multiple loose geometric shapes into unified files
- Prepare spatial datasets for offline GIS applications
- Syntax checks are strictly applied; incorrect strings will fail to convert
- Does not automatically assign coordinate systems unless defined
- Output coordinates default to base calculations

When to use this conversion
Convert when WKT geometry strings (often exported from a spatial database or generated by a script) need to live in a desktop GIS with attributes. Useful for assembling test datasets, importing one-off survey points, or migrating from a non-GIS spatial-text workflow.
Technical Details
GeoPackage is typically 40–70% the size of the source CSV (with WKT column). Binary geometry storage is much more compact than WKT text.
Common Errors & Fixes
- WKT not detected as geometry: -oo GEOMETRY=AS_WKT not passed. Fix: add the flag and specify the column name with -oo GEOMETRY_NAME=geom.
- Invalid WKT silently skipped: malformed strings drop rows. Fix: validate first with our WKT validator.
- CRS undefined: -a_srs forgotten. Fix: always pass an explicit -a_srs.
- Mixed geometry types in one column: GeoPackage layer needs one type. Fix: split into multiple files per type.
Alternative Tools
- PostGIS: load WKT into a staging table with ST_GeomFromText, then ogr2ogr export to GPKG
- shapely (Python): build a GeoDataFrame programmatically, save with .to_file
- QGIS: paste WKT strings into the "Geometry by expression" tool
- DB Browser for SQLite: import CSV, manually add GeoPackage metadata
Frequently Asked Questions
What is the primary benefit of this tool?
It allows developers to easily convert text coordinates into indexable database layouts.
How are column names matched?
Input database names map to corresponding table columns in the output files.
Can I convert complex polygon strings?
Yes, standard polygons and multi-polygon text strings are supported.
