Reproject an entire file to any coordinate reference system — searching the real EPSG registry, not a limited preset list. Your data's current projection is detected and shown automatically.
What This Tool Does
Detect Your Source CRS
Reads the actual coordinate system from your file itself (e.g. a Shapefile's .prj) the moment you upload, rather than assuming.
Search the Real EPSG Registry
Search over 7,000 real coordinate systems by name or code — not a limited preset dropdown.
Suggest a Local UTM Zone
One click gets you a locally-appropriate UTM projection based on your data's actual location, ideal for accurate metric distance and area work.
Reproject Accurately
Converts your data to the target CRS using pyproj's real transformation pipelines, not an approximation.
Frequently Asked Questions
How do I find the right EPSG code for my target projection?
Search by name (e.g. "UTM zone 43N", "British National Grid", "State Plane California") or by the numeric EPSG code directly if you already know it. The search covers the real, complete EPSG registry, not a limited preset list.
What CRS is my uploaded data actually in?
Shown automatically right after upload, detected directly from the file itself (e.g. a Shapefile's .prj file) rather than assumed.
What if I don't know what projection I need?
A locally-appropriate UTM zone is suggested automatically based on your data's actual location — a sensible default for most metric distance/area work, one click away.
What file formats are supported?
Upload GeoJSON, Shapefile (zipped), GeoPackage, KML/KMZ, or a spreadsheet with coordinates or WKT. Export the reprojected result in the same range of formats.
Is my data stored anywhere after conversion?
No — files are processed in memory for your request and discarded immediately afterward.
