1.11.5: Can't convert .HEIC files from context menu

Post by Doak »

Subject: 1.11.5: Can't convert .HEIC files from context menu
XnView: MP 1.11.5 - 64 bit
OS: Windows 11 25H2

Missing native XnShell integration
The standard XnShell "Convert..." menu is not available for HEIC files, default format for photo files on iPhones.
It would be very useful if HEIC files were handled the same way as JPG, PNG, TIFF, etc.

NConvert is a console application and have use this as workaround.
When launched from the Windows Explorer context menu, a console window briefly appears during the conversion.
It would be helpful if NConvert supported a command-line option to run without displaying a console window (for example --hidden, --background, or similar), or if a GUI-less Windows executable were provided.

To reproduce:
The XnShell "Convert..." context menu is not available for .HEIC files. As a workaround, I had to create a custom Windows Explorer context menu that calls NConvert directly.

Workaround:

Code: Select all

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\SystemFileAssociations\.heic\shell\ConvertToJPG]
@="Convert to JPG"
"Icon"="C:\\Program Files\\XnViewMP\\xnviewmp.exe,0"

[HKEY_CLASSES_ROOT\SystemFileAssociations\.heic\shell\ConvertToJPG\command]
@="\"C:\\Program Files\\XnConvert\\nconvert.exe\" -quiet -overwrite -out jpeg -q 95 -o \"$%%.jpg\" \"%1\""
