Convert a GeoTIFF map to a MBTiles map or a PNG tile map
The free QGIS software allows you to convert GeoTIFF maps into .mbtiles files for the MAPLIBRE map
engine, or .png files for the GOOGLE MAP and APPLE PLAN map engine. Follow this procedure to
convert your files:
1. Launch QGIS. Double-click on New Empty Project, under Project Templates.
2. Drag and drop your GeoTIFF file from your computer into the main QGIS window to bring your
GeoTIFF file into the software's main interface.
3. Ensure that your GeoTIFF file has been imported onto your PC screen. It appears in the Layers
menu on the left-hand side of the screen.
4. In the top bar navigation menu, click on Processing, then on the first option in the drop-down
menu, Toolbox. The conversion interface opens on the right-hand side of the screen.
5. To create a .mbtiles file, follow sub step A), to create a .png file, follow sub step B):
A. .mbtiles file - In the Toolbox, double-click on Raster Tools, then click on Generate XYZ
tiles (MBTiles) (See the blue box).
B. .png file - In the Toolbox, double-click on GDAL, then double-click on Raster
miscellaneous, then click gdal2tiles (See the green box). Click Run to start the conversion.
Note: If you follow step 5.B to create a .png file, the conversion process is complete after you click Run,
however, you must compress all new folders (.zip format) from the Output directory. Do not rename
the folders. The conversion can take over 1 hour, depending on the size of the original file.
If you follow step 5.A, continue with step 6 for the .mbtile conversion process.
