Tips to make .mmpk smaller?

[AcdenHelios]

Hey there,

I'm making an .mmpk file so I can take my map out into the field with Field Maps. However, the file size is 1.5GB and it takes forever to download on my phone! I suspect it's the .tiff file I'm using for the imagery, is there a way to make this smaller without having to sideload anything onto the phone? Any tips or tricks would be appreciated!

You could look into converting the .tif to another compressed format.   One option would be to use the Geoprocessing tool 'Create Map Tile Package' to create a .tpkx file, which has great performance on mobile devices when used in the mobile map package.    In this recent post I explained a bit about map tile packages, which could be of use to you.  https://community.esri.com/t5/arcgis-collector-questions/map-tile-packages/m-p/1222911#M13698
