XnView Software

XnViewMP 1.4.4 64bit
Windows11 (22H2), display resolution 3840x2160, win scaling 150%

Batch convert
avif saves as heic

To reproduce:
1. run clean portable XnViewMP
2. open test image 3. press CTRL+U to open Batch convert
default format settings 'Same as original'
4. press Convert button
file will be saved in .heic format instead of .avif


ps: .jfif saves as .jpg, but I see no issue here, as there is no option to save into .jfif

Crazy bug, but I can confirm it.

This problem is supposed to be fixed in XnView MP 1.4.5. Please check and confirm the bug fix here.
