Free Address to Lat/Long Converter — Geocode Any Address

What Is Geocoding?

Geocoding is the process of converting a human-readable address into geographic coordinates (latitude and longitude). This allows you to plot addresses on a map, calculate distances, or integrate location data into spreadsheets and GIS software.

Forward geocoding converts an address like "1600 Amphitheatre Parkway, Mountain View, CA" into coordinates (37.4220, -122.0841). Reverse geocoding does the opposite: given coordinates, it returns the nearest known address. This tool supports both directions, plus batch processing for converting many addresses at once.

Forward vs Reverse Geocoding

Direction	Input	Output	Use Case
Forward	Street address or place name	Lat/Long coordinates	Property lookups, mapping, data entry
Reverse	Lat/Long coordinates	Nearest address	GPS data analysis, field surveys

Batch Geocoding — Convert Hundreds of Addresses

Need to geocode a list of properties, customer addresses, or field sites? Switch to Batch mode, paste your addresses (one per line) or upload a CSV file, and click "Convert All." Results appear in a table with latitude, longitude, and status columns — ready to download as CSV.

Common batch geocoding use cases include: real estate agents converting MLS listings to map pins, farmers mapping field locations for precision agriculture, logistics companies plotting delivery routes, and researchers geocoding survey responses.

Six Coordinate Formats in One Click

After converting an address, the tool displays coordinates in six professional formats: Decimal Degrees (DD), Degrees Minutes Seconds (DMS), Degrees Decimal Minutes (DDM), UTM, MGRS, and Geohash. Click the copy icon on any card to copy that format to your clipboard.

How to Use This Tool

Forward geocoding: Type an address, optionally add a 2-letter country code, and click Convert. Coordinates appear in 6 formats with a live map.
Batch geocoding: Switch to Batch tab, enter addresses one per line or upload a CSV, and click Convert All. Download results as CSV.
Reverse geocoding: Switch to the Reverse tab, enter latitude and longitude, and click Find Address. The resolved address appears with a map.

Frequently Asked Questions

What is geocoding?

Geocoding converts a human-readable address (like "1600 Amphitheatre Parkway, Mountain View, CA") into geographic coordinates (latitude 37.4220, longitude -122.0841). Reverse geocoding does the opposite: it takes coordinates and returns the nearest known address.

How accurate is the address to lat/long conversion?

Accuracy depends on how specific your address is. A full street address typically resolves to within 10–50 meters. A city or region name resolves to its approximate center. The tool uses OpenStreetMap data via the Photon geocoding engine, which covers most global addresses.

Can I convert multiple addresses at once?

Yes. Switch to Batch mode, enter one address per line (or upload a CSV file with an "Address" column), and click Convert All. Results appear in a table with latitude, longitude, and status columns, and you can download everything as a CSV file.

Is the reverse geocoding feature free?

Yes. All features — forward geocoding, reverse geocoding, and batch conversion — are completely free. No sign-up, API key, or usage limits are required.

What coordinate formats are supported?

After geocoding, coordinates are displayed in six formats: Decimal Degrees (DD), Degrees Minutes Seconds (DMS), Degrees Decimal Minutes (DDM), UTM, MGRS, and Geohash. You can copy any format with one click.
