JPEG uses lossy compression that typically achieves 10:1 compression ratios with minimal visible quality loss for photographs. TGA is uncompressed, PSD uses RLE or ZIP, and GIF uses LZW compression.

PSD (Photoshop Document) is Adobe's native format that fully supports layers and layer masks. JPEG, GIF, and TGA are flat image formats without layer support.
