Hi,
I can’t found any Heic image viewer…any suggestion ?
Also when i try to import my Iphone’s Heic photo with Gthumb, Rapid Photo Downloader…it give me error
I could use the Ifuse method which work well but not simple for avoid already transfer file…
Thanks in advance
Hello,
Krita and Gimp can open and edit/export *.HEIC images.
Didn’t spend much time with such format, but i came across, and i have no idea for a viewer but someone might guide you in the right direction at some point. 
Hello,
Thanks for the suggestions, i know for Gimp, but i am looking for photo management / viewer.
I will see for Digikam…it’s seem it’s working with Heic, and importing Iphone’s photos. ps. install a lot of dependency
What do you use for importing photos ?
I am on Cinnamon
I don’t. Most of photos i get are from clients. 
I try Regards Viewer but it crash, so sad because it handle Heic file and seem to be great viewer
Try koko - is a decent image gallery viewer and seems to support heic too. Is in our repositories.
Thanks, it’s working, but no thumbnail…
Each file manager deals with thumbnails differently. Maybe you can build this packages from AUR:
heif heifthumbnailer qt5-heif-git
Doesn’t work 
I had this issue about half a year ago, I think I just installed libheif and used viewnoir to view. I initially had, I think, a color profile issue took a few extra minutes to correct though.
Will be trying koko out myself soon.
I tried both Xviewer and koko but none of them works. In fact koko does not show anything except a pitch black image and Xviewer shows a blurry black-and-white image. However, I can view it perfectly in gimp.
[Unfortunately, Manjaro made me TL1 after their server wipe and so I couldn’t post a screenshot of how it looks on Xviewer vs gimp Thanks Manjaro.]
Welcome back,
Manjaro didn’t make you anything. This forum is a fresh one, we all started from scratch zero.
