Rotate images in Windows with ImageMagick

Since rotating images in Windows causes images to loose quality, I decided to use ImageMagick to rotate images instead.

ImageMagick is a small command-line tool for image processing. Rotating images with ImageMagick is fairly simple:

Rotate right
magick convert -rotate "90" input.jpg output.jpg

Rotate left
magick convert -rotate "-90" input.jpg output.jpg

Rotate upside down
magick convert -rotate "180" input.jpg output.jpg

However, it quite tedious to run the command-line everytime you want to rotate an image, right?

So I made a registry file which adds the option to rotate with ImageMagick to the context menu (right click menu) in Windows. So it looks like this:

Here is the registry file below. Just save it as a .reg file and run it to import it.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT*\shell\ImageMagick - Rotate upside down]
@="ImageMagick - Rotate upside down"
"Icon"=hex(2):43,00,3a,00,5c,00,70,00,6f,00,72,00,74,00,61,00,62,00,6c,00,65,\
00,5c,00,49,00,6d,00,61,00,67,00,65,00,4d,00,61,00,67,00,69,00,63,00,6b,00,\
5c,00,6d,00,61,00,67,00,69,00,63,00,6b,00,2e,00,65,00,78,00,65,00,2c,00,30,\
00,00,00

[HKEY_CLASSES_ROOT*\shell\ImageMagick - Rotate upside down\command]
@="C:\portable\ImageMagick\magick convert -rotate \"180\" \"%1\" \"%1\""

[HKEY_CLASSES_ROOT*\shell\ImageMagick - Rotate left]
@="ImageMagick - Rotate left"
"Icon"=hex(2):43,00,3a,00,5c,00,70,00,6f,00,72,00,74,00,61,00,62,00,6c,00,65,\
00,5c,00,49,00,6d,00,61,00,67,00,65,00,4d,00,61,00,67,00,69,00,63,00,6b,00,\
5c,00,6d,00,61,00,67,00,69,00,63,00,6b,00,2e,00,65,00,78,00,65,00,2c,00,30,\
00,00,00

[HKEY_CLASSES_ROOT*\shell\ImageMagick - Rotate left\command]
@="C:\portable\ImageMagick\magick convert -rotate \"-90\" \"%1\" \"%1\""

[HKEY_CLASSES_ROOT*\shell\ImageMagick - Rotate right]
@="ImageMagick - Rotate right"
"Icon"=hex(2):43,00,3a,00,5c,00,70,00,6f,00,72,00,74,00,61,00,62,00,6c,00,65,\
00,5c,00,49,00,6d,00,61,00,67,00,65,00,4d,00,61,00,67,00,69,00,63,00,6b,00,\
5c,00,6d,00,61,00,67,00,69,00,63,00,6b,00,2e,00,65,00,78,00,65,00,2c,00,30,\
00,00,00

[HKEY_CLASSES_ROOT*\shell\ImageMagick - Rotate right\command]
@="C:\portable\ImageMagick\magick convert -rotate \"90\" \"%1\" \"%1\""

To use it:

• Download ImageMagick portable and place it in the folder C:\portable\ImageMagick\.
• Download or save the registry file as a .reg file.
• Run and import the registry file.
• Voilà!

Don’t let Windows reduce the quality of your images again! 😉
