Best Way to Crop / Resize

[Connolly Music Creations]

I have a .png which is 3840 x 2160px and I want as much of that to fit into a 1400 x 1400 for a website.  Should I crop it or resize it?  I just need it centered with and as much of the image intact as possible.  Thanks

If you just need the center ➤ crop it, because resizing will alter the quality.
Also it's better to crop first and resize after (if the center that you need don't fit the dimension 1400x2), especially with this size of resize, better to resize a little bit than a huge resize.
Last but not least, use the LoHalo (or NoHalo) interpolation.

Centered. Set up 50% guides Image -> New Guide (by percent)
Crop Tool. Fixed Aspect Ratio and enter 1:1 / Expand from center / Delete cropped pixels 
With a size of 2160 that gives as much as possible.

   

Scaling to 1440 pix is 2/3rds (66.66%) which is not too much.
For reference: Not much to choose between them. 
LoHalo method: when you downscale an image thats less than a half of the original size
NoHalo method when you do not reduce the size much (rotate, shear or something)
If you have gimp_gmic_qt installed then there are some good scaling options there.

Normally I use the crop tool this way:
- set the crop tool to 'Fixed'
- set the dimension, here : '1400:1400'
- drag the crop area to maximum
- move the crop selection for the best image frame
