Use this interactive demo to learn how to combine shapefile features into one using QGIS.

Quick summary

Merging shapefiles in QGIS lets you combine two or more vector features into a single geometry using the built-in Merge Selected Features tool. This step-by-step process requires enabling Toggle Editing mode, selecting your target features, and confirming the merge through a dialog box.

Steps

Select a shapefile layer from the Layers Panel and click the Select Features tool at the top.
Drag your cursor across the polygons or geometry of the file, or press Ctrl + A (Windows) / Cmd + A (Mac) to select two or more features to merge.
Click the Toggle Editing tool on the top menu to enable editing mode.
Click the Merge Selected Features tool from the top toolbar.
Review the merge dialog box to confirm how features will be combined, then click OK.
Open the attribute table of the merged layer to verify the result.
Confirm that the merging was successful in the updated layer view.

📌 Why this matters

Merging shapefiles in QGIS is a core GIS workflow that allows analysts and spatial data professionals to combine adjacent or overlapping polygon features into a single unified geometry. This capability is essential for simplifying complex datasets, reducing redundant boundaries, and preparing clean vector data for mapping, analysis, or export. QGIS is a free, open-source GIS platform widely used in urban planning, environmental science, and geospatial research, making this skill accessible to a broad audience. Knowing how to merge features directly within QGIS eliminates the need for external tools and keeps your spatial analysis workflow efficient and reproducible.
