XnView Software

Your suggestion with the changed quotation marks was correct.
It works!
Many Thanks.

Hi,

I installed the executable and subfolders with plugins from xnview_full.zip new.
The new command is:
"C:\Program Files\XnView\nconvert.exe" "-out jpeg %1"

I see a brief command window but no new file is written.

Regards
Peter

Hallo,

I want to use nconvert with parameters to convert webp to jpeg in windows explorer (old menu).

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\SystemFileAssociations\.webp\Shell\convert]
@="Zu JPG konvertieren"

[HKEY_CLASSES_ROOT\SystemFileAssociations\.webp\Shell\convert\command ...

Shell extension 4.1.2.0 works fine on my Windows 19043.962 (21H1).
But i would like a progress bar or message box or window on long file operations.
On resizing 20 or more big pictures e.g. 14000px to 50% the windows explorer seems to freeze and the mouse hourglass appears.
It would be nice to see ...
