Differences Between ImageMagick Version 6 and Version 7
+

ImageMagick currently maintains two versions of its software: version 6 and version 7. ImageMagick released version 7 in 2016, and the platform encourages its user base to upgrade to the latest version. However, version 6, sometimes referred to as Legacy ImageMagick, is still maintained. A patch for Legacy ImageMagick version 6 was released as recently as October 2025. A link to Legacy ImageMagick’s repository can be found here.

The structure of ImageMagick commands in the examples on ffmprovisr have primarily been formatted for compatibility with Legacy ImageMagick. While many commands that use convert and mogrify can still be executed in version 7, not all are guaranteed to work. Many version 7 commands follow a similar structure to those of version 6, but with magick being used to start commands rather than convert and mogrify in most cases. Version 7 commands can be found at the bottom of each ImageMagick example on ffmprovisr.

+

New ImageMagick users and current Legacy users considering upgrading should assess the differences between each version before choosing which one to install. Below are a just a few of the differences users should be aware of.

+

Unlike Legacy ImageMagick, as a default, version 7 stores image pixels with High Dynamic Range Imaging (HDRI). This is typically with a bit depth up to Q16. To disable HDRI, the following command should be executed:

+

./configure --disable-hdri

+

Some Legacy ImageMagick command options are no longer supported by version 7, including but not limited to: +

-maximum + -median + -minimum + -origin + -passphrase
+

Lastly, those operating Legacy commands on older hardware should take steps to ensure version 7's compatibility with their current system. Saved scripts that leverage Legacy command structures may need to be individually updated.

+

For further reading on differences between ImageMagick versions, including a full list of deprecated Legacy command options, users can refer to the Porting Guide on ImageMagick’s website.

+
Convert
The convert command is used to change the composition of an image (i.e. its format, size, position, etc.).
+
Identify:
The convert command is used to give basic information about image file(s) such as format, size, file name, or whether or not the file is incomplete or corrupt.
+
Mogrify:
The mogrify command is similar to the convert command, in that it modifies images, however, it does so to the original image file. This means the original image will be overwritten.
+
Montage:
The montage command creates a composite image out of multiple individual images.
+
Compare:
The compare command allows a user to see the differences between two input images.
