Once you become more familiar with converting to .DDS, I would recommend sticking to this image format for GG as it is best for optimizing your game.
Further, if you wish to explore the possibilities, play around with textures at 512x512, 256x256 and 128x128 resolutions. You will be surprised at how much memory you can save whilst allowing your textures to remain the same, on look and fidelity (relatively).
AMD Ryzen 7 2700 @ 3.2 GHz, 8 Cores, 16 Threads, 32GB DDR4 RAM @ 3000 MHz, Nvidia GTX 1060-6GB, Windows 10, x2 ASUS TUF Gaming VG259QM 24.5" Monitor(s) (1920 x 1080; 32 Bit colors) @ 280MHz.
