.\ImageMagick-7.0.8-14-portable-Q16-x64\convert.exe ".\2018 Bass Family Fall004.jpg" -resize "1500x" -quality 60 -depth 24 test.jpg

-strip gets ride of details like camera fstop etc but it also removes the color profile resulting in a washed out look

If you have the AdobeRGB1998.icc file this is the best conversion:
.\ImageMagick-7.0.8-14-portable-Q16-x64\convert.exe ".\2018 Bass Family Fall004.jpg" -resize "1500x" -quality 60 -depth 24 -strip -profile ".\AdobeRGB1998.icc" test.jpg
