![]() ![]() You can give it a base name, say 'convert', and when it prompts you for autofill options, choose 'Fill with numbers'. In the Converted column, click the ellipsis next to the field in the first row, and choose a directory and file name for the converted images. Click 'Select all', then 'OK'.Ĭlick the drop-down in the Expand column for each row, and select 'rgba'. In the context menu that opens, choose 'Select from open layers'. Click the ellipsis button (.) In the 'Input layer' column on the first row. To speed things up, click the 'Run as batch process.' button on the top right. ![]() Double-click the translate function under the GDAL algorithms. In the search box at the top, type 'translate'. This should open a panel next to the map canvas.Ĭlick the drop-down list at the bottom to select 'Advanced interface'. If it's multiband color, singleband grayscale or singleband pseudocolor, it should merge just fine without conversion and you can skip ahead to step 2.įrom the menu, choose 'Processing > Toolbox.'. If it's paletted, it should say so next to 'Render type'. If you are not sure, open the layer properties window and click on the Style tab. If they are already in one of those formats, you can skip this step. If your TIF files are paletted, you will need to first convert them to RGB or RGBA. Step 1: Convert paletted files to RGB or RGBA I will demonstrate how to merge these using the QGIS Processing algorithms. Here I have an example with three rasters loaded. I prefer to use the Processing tools, which use the layers as inputs. This can be tedious in a directory with hundreds of files. What I don't like about that method is that it requires you to find the files you want to merge in your file system. The tutorial in the answer posted by Venug uses the Raster > Miscellaneous > Merge functionality.
