Format Converter
Convert between GeoJSON, KML, GPX, Shapefile, and CSV — all processing happens in your browser.
Convert Any GIS Format
A universal format converter for the most common geospatial file types, running entirely in your browser.
5 Major Formats
Convert between GeoJSON, KML, GPX, Shapefile (SHP), and CSV. Each format is parsed to GeoJSON as an intermediate representation, then exported to the target format.
100% Client-Side
All conversions happen in your browser using JavaScript and WebAssembly. No files are uploaded to any server. Your data never leaves your device.
Automatic Detection
Drop any supported file and the format is automatically detected from the file extension and content. No manual format selection needed on the input side.
How to Convert GIS Files
Upload or Paste
Drag and drop a file onto the input area, or paste GeoJSON/KML/GPX/CSV text directly. For Shapefiles, upload a .zip or select .shp + .dbf files together.
Review Parsed Data
The converter detects the format automatically and parses your data. Review the feature count and geometry types to verify the import was successful.
Choose Target Format
Select the output format from the toggle buttons. The source format is automatically disabled. A live preview is shown for text-based formats.
Download or Copy
Click Download to save the converted file, or Copy to clipboard for text formats. Shapefile exports are delivered as a ZIP containing .shp, .dbf, and .shx files.
Why Use Our Format Converter
Shapefile Support
Read Shapefiles from ZIP archives or individual .shp + .dbf files. Export to Shapefile as a ZIP package compatible with QGIS and ArcGIS.
Smart CSV Parsing
Automatically detects latitude and longitude columns from common naming conventions (lat, latitude, y, lng, lon, longitude, x).
Live Preview
See the converted output in real time for text-based formats. Binary formats show file metadata and download directly.
Smart Warnings
Get clear warnings about format limitations. For example, GPX does not support polygons — the converter tells you which features were skipped.
100% Free
No usage limits, no account required. Convert as many files as you need at zero cost.
Privacy First
All processing happens locally in your browser. No data is sent to any server. No tracking, no cookies, no analytics.
