Raster profile

MapTiler Desktop has an option for turning large images into zoomable tiles. It is very useful in situations when you have an image which has few dozens or even hundreds of megapixels (e.g. high-res scan of an old painting) and you want to publish them online and allow users to zoom through such a picture.

Raster profile

Raster image into tiles

On the start screen, select the Raster Tiles option. Now drag and drop (or load) an image inside. With Raster Tiles profile, you can load only one image at a time. Now you have an option to View the picture and Color correct if needed (note: this option is intended for matching colors of different maps and not as a simple image processing tool).

In the next step, you have to select the output formatFolder option and GeoPackage are supported.

Folder or GeoPackage

After you click on Render, you will either get for the Folder option a folder with leaflet.html and openlayers.html HTML files (and a folder with all images for every zoom level). You can open the HTML files in any web browser or upload the whole folder via FTP to any web server.

The GeoPackage option produces one .gpkg file which can either be view by specialized software or directly uploaded via MapTiler to any supported cloud service and served to users from there.

Advanced options

Advanced options are available for Raster profile as well with the same settings options as for map rendering.

Advanced options

Zoom settings

Zoom settings allow defining for what zoom levels will MapTiler create tiles. The default values depend on the picture size; any change can be easily reset to the default value.
