WKT Parser & Converter
Convert between WKT, GeoJSON, and WKB formats instantly. Auto-detect input format, preview geometry on an interactive map, and copy results with one click.
Three-Way Format Conversion
Seamlessly convert between WKT, GeoJSON, and WKB hex — the three most common geometry interchange formats in GIS.
WKT ↔ GeoJSON ↔ WKB
Convert any geometry between Well-Known Text (WKT), GeoJSON, and Well-Known Binary (WKB) hex formats. Supports Point, LineString, Polygon, and all Multi* types including GeometryCollection.
Auto Format Detection
Paste any geometry string and the parser automatically identifies whether it is WKT, GeoJSON, or WKB hex. No need to specify the format — just paste and convert.
Interactive Map Preview
Converted geometry is rendered on an interactive map with automatic zoom-to-fit. Inspect points, lines, and polygons visually to verify your conversion results.
How to Convert WKT / GeoJSON / WKB
Paste Your Geometry
Enter WKT, GeoJSON, or WKB hex string in the input panel on the left. You can also share a URL with pre-filled input.
Select or Auto-Detect Format
Choose the input format manually, or leave it on Auto to let the parser detect it automatically from the input content.
Click Convert
Press the Convert button to transform your geometry into all three output formats (WKT, GeoJSON, WKB hex) simultaneously.
Copy or Preview Results
Switch between output tabs to view each format. Use the copy button for one-click copying. The map preview shows the geometry visually.
