Can someone please elaborate one what each of these settings do in regards to output?

I used “DEFLATE” compression and I am able to download the GeoTiff RAW file, but every other filetype just says “Downloading” and spins forever. I assume it is trying to compress on the fly, or maybe not at all.
JPEG:
The best choice for Orthophotos as it will yield the lowest file-size with minimal loss in image quality. Not appropriate for multispectral or DEM products as the compression will change the values of the data.
LZW:
Legacy lossless compression. Will not perform well unless data repeat a lot and don’t vary much.
Packbits:
Legacy lossless compression. Similar characteristics to LZW but worse compression ratio.
Deflate:
Modern lossless compression (zip file compression). Should yield acceptable compression ratio, wide compatibility (default choice), good performance.
LZMA:
Modern lossless compression (7zip file compression). Should yield better compression than Deflate, more limited compatibility, lower performance.
None:
No compression. Huge files, widest compatibility.
Compression is done on the fly, so your Task Manager should show things working in the background. It can take a bit for sure!
