Hey Product Hunt! 👋 I built CoordConv because I kept running into the same frustration — switching between UTM, DMS, and decimal degrees in field and GIS work always meant juggling multiple tools or copy-pasting into sketchy converters that phone home your data. CoordConv runs 100% in your browser. No account, no server, no data leaving your device — ever. Right now it supports 7 formats (DD, DMS, DDM, UTM, MGRS, Geohash, Plus Code) with an interactive map preview on every conversion. The batch converter handles CSV and pasted tables for high-volume workflows. Would love feedback on: → Which coordinate formats you use most → Any edge cases or input formats the parser misses → What you'd want to see next Happy to answer any questions about how it works under the hood. Thanks for checking it out! 🗺️
