Help with heic files

Hi.
I have an heic image file which I know has 16 images inside.
I want to "extract" the content into individual files in jpg format, in some batch processing.
I'm trying with imagemagick on the command-line but only get the first image.
Can someone please tell me the correct command-line syntax?

example of the last thing I tried:
convert *.heic[0-15] *.jpg

Thanks!

 

Maybe you could try XnView MP
https://www.xnview.com/en/

 

Thanks, I'll check that one!

 

This was not helpful.
However, this worked:

for file in *.heic; do heif-convert $file ${file/%.heic/.jpg}; done

I'm not sure if heif-convert is part of Imagemagick though.
It probably comes from package libheif-examples instead.

 

My script is a bit different:

Code:

for i in *.heic; do heif-convert -q 100 "${i}" "${i%.heic}.jpg"; done

(less compression in the jpg)

 

Thanks @nicolaasjan !

 

And for Windows (bat file):

Code:

@echo off
for %%f in (*.heic) do (
    echo Converting %%f to %%~nf.jpg
    heif-convert -q 100 "%%f" "%%~nf.jpg"
)

Ensure heif-convert.exe is installed and in the system's PATH.

I have no idea where to get a recent compiled executable for Windows. Maybe compile from source?
There is a rather old one here.

I do know that IrfanView with plugins can batch convert them, but you also have to install the necessary “HEIF Image Extensions” and “HEVC Video Extensions” MS Store Apps.
The HEVC extension is not free any more, except when you go to the store via this direct link:

Code:

ms-windows-store://pdp/?ProductId=9n4wgh0z6vhq
