GeoTIFFs are already georeferenced data, however for some use cases, you may require an additional world file. This article will walk you through the process of generating a tfw world file from your downloaded GeoTIFFs using QGIS.

You can download QGIS here:
If you are using a Windows computer, it is recommended to download the long-term release (most stable) standalone installer.

Note that this procedure is actually done using the gdal_translate utility (, but it can be performed via the QGIS interface. 

1. In QGIS, go to Layer > Add Layer > Add Raster Layer... Then select the GeoTIFF you wish to create a tfw for.

2. Once the file has finished loading, click on Raster > Conversion > Translate (Convert Format)... 

3. In the Translate (Convert Format...) window that appears, first ensure that your GeoTIFF is entered in the Input Layer field (it should automatically be there, assuming it is the only file you have loaded into this QGIS session).

4. Click on the Select... button for the Output file field. Choose where to save your duplicate GeoTIFF and the accompanying tfw file then type in the desired filename.

5. Once those details are complete, click on the pencil icon beside the text box with the gdal_translate script. This will grey out all the options above it and allow you to edit the script inside the text box.

6. At the end of the existing script, type in " -co tfw=yes" then click OK. That's it! You'll be notified by a pop-up window once the process is complete.

I still can't do it!
