Merge multiple vector files online: SHP, GeoJSON, KML, KMZ, GPX, GPKG, DXF and CSV in any combination, combined into a single file with all features and attributes preserved — processed locally in your browser.
Support uploading multiple files for merging at once
Local processing, data not uploaded to server, protecting your data privacy
Complete retention of all features and attribute information
Upload multiple geographic data files for merging
Vector Merge combines multiple vector files into a single layer. Upload as many GeoJSON or Shapefile files as you like and the tool concatenates their features — with all attributes preserved — into one output you can download immediately. The summary shows file count, total feature count, and geometry types before you commit.
It solves the everyday problem of fragmented data: province-level files that should be one national layer, tiles downloaded separately from an API, or monthly exports that need to become a single dataset. Nothing is uploaded — merging happens in your browser, so even sensitive layers stay on your machine.
Upload two or more vector files, dragging them in together or adding more with the "Add More Files" button; each file's feature count is listed.
Start the merge — all features and attribute fields are combined locally in the browser into a single layer, with totals shown for files, features, and geometry types.
Download the merged file and optionally reset the tool to process another batch.
ANo. The merged layer keeps the union of all fields; features coming from a file that lacks a given field simply have that field empty. Fields with identical names but different meanings will be mixed, so check your schema before merging.
AYes — points, lines, and polygons can all be merged into one output. Note that some downstream tools (and the Shapefile format itself) prefer single-type layers, so consider splitting by type afterwards if a target system requires it.
AThere is no fixed limit, but since everything runs in browser memory, very large or very numerous files may exhaust available RAM. For huge datasets, merge in several passes and combine the intermediate results.
ANo. The merge is a straight concatenation that preserves every feature — exact duplicates in the inputs remain duplicated in the output. Use the Dissolve or Extract tools afterwards if you need to deduplicate or filter the combined layer.
AAll mainstream vector formats: SHP, GeoJSON, KML, KMZ, GPX, GPKG, DXF, CSV, TopoJSON and more — and they can be mixed freely, e.g. one SHP plus two GeoJSON files into a single output.
AYes. Multiple KML (or KMZ) files merge directly, and they can be combined with SHP, GeoJSON and other formats; the output format is your choice.
AEach file is parsed in its own CRS and the merged output is written in WGS84 (EPSG:4326). Source .prj files or CRS declarations are applied automatically.
