Your editing software is the important factor. There are several photo
editing application which can perform non-destructive crops which are
reversible, among them Photoshop CC, Lightroom Classic CC, On1 Photo RAW
2018, Luminar 2018, AlienSkin Exposure X3, & Affinity Photo.

As a Mac user BMP is far removed from my thoughts, and workflow. I shoot
RAW+JPEG, and use a RAW workflow, and usually the only time I use JPEG is
when I produce one for online sharing. Though recently I have been using
SOOC JPEG from my Fujifilm cameras, and their great film simulations.

Not being a Windows user, I don’t understand this idea of holding on to the
BMP format when there are much better ways to go.
