XnConvert "Preserve Extension" Not Working

[toodles]

When batch converting images to webp, the extension is always changed to .webp even when this option is checked.

Using XnConvert Version 1.79 - windows x64 (Jan 30 2019) - Libformat version 7.25.

Thanks for any help anyone can offer.

which input filename do you use?

[toodles]

Happens with any filename. I've been using "Add Folder..." and the "Delete Original" is also checked.

Example: test.png file that I want converted to a webp, but to remain "test.png" will be "test.webp" after conversion.

what do you have as output filename?

[toodles]

The default "{Filename}"

[xnview]

The default "{Filename}"

I've tried and it works correctly. Could you post a screenshot of Output tab?

And here's all this too just to make sure I'm not doing something stupid. Thanks for your help

sorry i had not understand, why do you want to keep .jpg for .webp?
'Preserve extension' is only to keep extension if format is not changed, for example .jpeg and not change to .jpg

I use webp for making images in visual novels smaller. The exact filename and extension must be unchanged for it to work. Otherwise, have to re-write the scripts with new extensions on sometimes thousands of images.

I totally understand if this was not what you intended this function to do, but would be very helpful to many people if it worked as stated. Thanks again for your time, and the great program you've made. Really appreciate it.
