Getting "Invalid Parameter - -fuzz" on ImageMagick convert command on Windows 10

Solution 1:

Windows has an existing convert.exe program to convert a FAT volume to NTFS. It appears this is being found earlier in your %PATH than the ImageMagick convert.exe.

You can verify this by running convert without any parameters. If you get a message 'Must specify a file system' then you are not running the ImageMagick executable.

If this is indeed the case, you can get around this by specifying the full location of the executable you want to run. I am guessing but it is probably:

C:\Program Files\ImageMagick-7.0.10-Q16\bin\convert.exe [parameters...]

You could add the ImageMagick bin directory to your %PATH but you would need to place it earlier than the main Windows directories for it to run before the 'standard' convert.exe but be aware that any other binaries in the IM folder would also take precedence. Another option is to add the IM directory to the end of your %PATH (it may be there already) and rename the IM convert.exe to something unique.

Solution 2:

You can also use magick convert instead of convert.
