How do ROTATE a photo without losing quality?
Windows Photo Viewer and IrfanView - it can, but changes the size of the file.
I care about the real and original size

I care about the real and original size

Such a program could be difficult to find, because even Adobe Photoshop CS6 changes the file size of a .JPG file
when rotating, e.g. from landscape to portrait.

However, the original size remains unchanged, i.e.
ExifImageWidth: 4176, ExifImageHeight: 2784 becomes ...
ExifImageWidth: 2784, ExifImageHeight: 4176

I downloaded the plugins for IrfanView, but every time I want to rotate image it informs about the lack of a plugin. I have no idea how to solve it.
IrfanView 4.52 x64
C:\Program Files\IrfanView\Plugins\jpg_transform.dll

IrfanView

Can't load PlugIn: "JPG_TRANSFORM.DLL" !
Please install or update PlugIns from IrfanView homepage!
(64 bit)

OK

EDIT:

When rotating JPEG photos, most image editors decode the photo, rotate the bitmap and then re-encode it back to JPEG. This process decreases the final image quality. Unlike those tools, JPEG Lossless Rotator does not recode the images and performs a special lossless block transformation instead, which helps to preserve the quality of the images.

… and do you get the real and original size?

A little bigger size.
