I am using QGIS and currently have Tiff files that when uncompressed are upwards of 1 GB. When compressed, they are around 250 MB. I am trying to reduce this file size dramatically whether it be by converting to a different file type (jpeg, png) or doing something else from scratch. The Tiff files are georeferenced aerials so if I convert to jpeg or png then I will also need a world file to reference my images. The only way I have been testing this is through Raster > Conversion > Translate where I select my input layer and my output file type. I am trying to reduce these files to around 100 MB if possible.
If there is a different or better way to reduce these files let me know. The image is an example of the type of image I am using.
