My photos are too large. Is there a way of making them smaller without affecting the quality?

Hello!
I´m looking for a DJI drone, that can make great pictures. Of course I want to do videos too, but the most i want to do aerial photographs, and I want to hear a tip from you, which drone should I by from DJI?

Thank you a lot.....Greetings from Austria!

Here's a few of mine. All frames taken from 4K videos done with my P4 - which appear sadly better than photos the P4 takes.

Photos:
The Carillion on Lake Burley Griffin in Canberra, Australia. Normal lense.
Wind turbines on the edge of Lake George in NSW, Australia (for perspective - 80m to the hub with prop diameter of 55m, and they are access roads). Normal lense.
Jindabyne on the edge of Lake Jindabyne in NSW, Australia. Polarising lense.
