Find answers to common questions about GeoTools.cc
GeoTools.cc is a free, browser-based platform for geospatial data processing. It offers tools for data format conversion, coordinate transformation, geocoding, and data visualization; all running entirely in your web browser.
Yes, all tools on GeoTools.cc are completely free to use. No registration or payment is required.
No. You can use all tools instantly without creating an account or providing any personal information.
GeoTools.cc works best in modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version for optimal performance.
No. All data processing happens entirely within your web browser using WebAssembly and JavaScript. Your files never leave your device. When you close the browser tab, all processed data is cleared from memory.
No. We have no access to your files and do not store any processed data. The only information we collect is anonymous usage analytics (page visits, browser type) via Google Analytics.
Yes. Since all processing is client-side, your data remains on your device at all times. This makes GeoTools.cc suitable for processing sensitive geospatial datasets.
GeoTools.cc supports a wide range of geospatial formats including GeoJSON, Shapefile, KML, KMZ, GPX, CSV, TopoJSON, DXF, GeoPackage, and WKT. Check our Data Formats page for the complete list of supported conversions.
Shapefiles consist of multiple files (.shp, .shx, .dbf, .prj). Compress all related files into a single .zip archive, then upload the .zip file. GeoTools.cc will automatically detect and process the Shapefile.
Most formats support files up to 500MB. For Shapefile archives (.zip), the limit is 200MB. Large files are processed using stream-based parsing to maintain browser responsiveness.
Currently, GeoTools.cc processes one file at a time. However, conversions are fast and you can process multiple files sequentially without any restrictions.
Common reasons include corrupted or incomplete files, unsupported format variations, files exceeding size limits, or missing required components such as a .prj file for Shapefile. Try validating your file before uploading.
GeoTools.cc supports WGS84 (EPSG:4326), Web Mercator (EPSG:3857), UTM (all zones), and thousands of other coordinate reference systems searchable by EPSG code or name.
Select UTM as the source CRS, enter your UTM coordinates along with the zone number, then select WGS84 as the target. The conversion result will display latitude and longitude values.
For geographic coordinates (latitude/longitude), use decimal degrees (e.g., 39.9042, 116.4074). For projected coordinates, enter the X (easting) and Y (northing) values.
GeoTools.cc uses the Nominatim (OpenStreetMap) geocoding service for address lookup and reverse geocoding. Results may vary in accuracy depending on the region.
Yes. Upload a CSV file containing addresses in a column, and GeoTools.cc will batch-geocode them and add latitude/longitude columns to the output file.
Geocoding accuracy depends on the address format, region, and available data. For best results, provide complete addresses including city, state/province, and country.
Large files require more processing time. Try using a smaller test file first to verify the conversion works. Closing other browser tabs and applications can also improve performance.
Verify that your file is in a supported format and not corrupted. For Shapefiles, ensure all component files (.shp, .shx, .dbf, .prj) are included in the zip archive. Try re-downloading or exporting the file from your source application.
Some format conversions may result in minor differences due to precision loss, coordinate system transformations, or format-specific limitations. These differences are usually negligible for most use cases.
