XnView Software

Using XnView MP 1.5.2 on iMac with Intel processor.

Whenever I try to save an image in AVIF format, I get the error shown in the last screenshot below. XnView MP will create a file with the extension .avif having 0 bytes. The format of the original image doesn't matter. The file name doesn't matter either.
     

it's AVIF is not supported on MacOS

It would be great XnView MP would support it. AVIF seems to be a useful format, it has better compression ratio than WEBP. GraphicConverter 12 on Mac does support it. So there's no general reason why it can't be done on Mac.

See issue for current status and some details.

This problem is supposed to be fixed in XnView MP 1.6.0. Please check and confirm the bug fix here.

Not fixed. I still get the error "An error occurred during saving."

you need to install libheif with brew

That's quite uncomfortable for the user. Other apps such as GraphicConverter are able to save files in AVIF format without such inconveniences.

yes i understand, i need to package the libheif library

Thank you very much for your efforts!

Currently there is only libraries for arm64 in the package

I have a Mac with Intel processor.

Today I got a new Mac with Apple chip, and I can confirm that saving as AVIF does work. Thank you very much!
