How can I reproject a shapefile using QGIS?

All geographic data is tied to some projection or coordinate system. If you know the starting coordinate system or projection of your shapefile, you can quickly export the data into another coordinate or projections system using QGIS. What Files Are Needed to Reproject a Shapefile?

Do you need a.prj file for a shapefile?

In order for any GIS software application to understand the projection or coordinate system that a shapefile is stored in, you will need to have a file with the same name that has the .prj extension. When you open up a .prj in a text editor, you will see markup information about the coordinate or projection system:

How can I change the CRS of my shapefile?

You can right-click on your shapefile in the table of content, choose “save as” and define the projection system that you want as an output. If you already know the real CRS, and even it is read properly by QGIS, the answer is easy. In QGIS 3.2: right click on your layer –> “export layer…” and change CRS at the same time like this:
