CoordinateMapper is a fast, free-to-use browser-based tool for converting and visualising geographic coordinates. Unlike simple converters, it lets you work directly on an interactive map. Paste or upload coordinate lists, automatically detect formats (even messy ones), draw points, lines and polygons, group locations, and export results to CSV, KML or DXF.

Hi all! 👋 I’m the creator of Coordinate Mapper. I built it after repeatedly needing a quick way to convert and check coordinates without opening heavy GIS software. What started as a simple converter slowly turned into a full browser-based tool for working with coordinate data. With CoordinateMapper you can: • Convert between multiple coordinate formats • Paste bulk coordinates or upload files • Automatically detect formats, even when the formatting is messy • Visualise everything on an interactive map • Draw points, lines, and polygons • Export results to formats like CSV, KML, and DXF The goal is to make everyday coordinate tasks faster and easier for anyone working with location data. I’d love to hear your thoughts: • Are there features you wish existed in tools like this? • Any workflows you’d like to see supported? Thanks for checking it out!
