SMGIS Universal GIS Tools

GIS Format Converter

Convert between Shapefile, GeoJSON, GeoPackage, CSV, KML/KMZ, and DXF — any supported format to any other, in three steps, with no analysis or styling required. All conversion happens on the server; your file is never processed in the browser.

.csv.tsv.xlsx .xls.geojson.gpkg .shp folder.zip (Shapefile).kml.kmz
Max file size: 50 MB
Shapefile? Drag its folder in directly, or — no need to zip it first.
Geometry Type
Lat / Lon Columns
WKT Column
Coordinate Sequence
GeoJSON
Shapefile
GeoPackage
CSV
KML
KMZ
DXF
GeoJSON supports mixed geometry types and every property field — the safest general-purpose choice.
Want custom icons, colors, and folders in your KML output instead of one flat default style? Use KML Studio for that.

7 Output Formats

GeoJSON

The open, web-friendly standard — ready to drop straight into most modern GIS and mapping libraries.

Shapefile

Exported as a ready-to-use .zip with all required companion files (.shp, .shx, .dbf, .prj).

GeoPackage

A single SQLite-based file, the modern successor to Shapefile with none of its geometry-type or field-name limits.

CSV

Geometry flattened to coordinate columns for spreadsheet or database use.

KML / KMZ

Ready for Google Earth, with a single neutral default style applied.

DXF

For bringing GIS geometry into AutoCAD or other CAD software.

Frequently Asked Questions

What formats can I convert between?

Input: CSV, Excel (.xlsx/.xls), GeoJSON, Shapefile (as a .zip), GeoPackage, and KML/KMZ. Output: GeoJSON, Shapefile, GeoPackage, CSV, KML, KMZ, and DXF. For CSV/Excel, geometry can be built from latitude/longitude columns, a WKT column, or a coordinate-sequence column.

Why can't I convert mixed geometry types to Shapefile?

Shapefile requires every feature in a file to share one geometry type (all points, all lines, or all polygons) — a real limitation of the format itself, not something this tool can work around. GeoJSON, GeoPackage, and KML all support mixed geometry types in one file.

Does converting to KML apply any styling?

A single, neutral default style is applied to every feature — this tool is built for fast format conversion with no configuration required. For custom per-category icons, colors, and popups, use KML Studio instead.

Is there a file size limit?

Uploads are capped at 50MB, which keeps conversion fast and reliable for everyone using the free tool. For larger datasets, get in touch.

Is my data stored anywhere?

No — files are processed in memory for your request and discarded immediately afterward.
