Any app on Ubuntu to open HEIF (.heic, High Efficiency Image File Format) pictures?

Gimp does, libheif is in the repo for Ubuntu 17.10 or 18.04, for 16.04 and 14.04 there is a ppa.

@Temüjin Thanks for the hint regarding mp4client. I have not found time to try this.

As monkeybrain20122 mentioned there is a plugin for GIMP and the most recent GIMP version automatically comes with this plugin:
GIMP 2.10.2 with support for HEIF image format (https://www.gimp.org/news/2018/05/20...-2-released/):
You can install/upgrade to GIMP 2.10.2 on Ubuntu via Flatpak or wait for Otto’s GIMP PPA for Ubuntu 18.04 LTS to be updated with the new build (https://www.omgubuntu.co.uk/2018/05/...ome-twitch-app).

I am using Fedora 28 and came across XnView. I tried XnView MP, but no plugins for the HEIC file type. I then tried the XnView windows version (using wine) and install the HEIC plugin, which then works perfectly. Has anyone found a better way?

On ubuntu 18.04:

sudo apt install libheif-examples

then:

heif-convert IMG_1605.HEIC IMG_1605.jpg

NOTE: you must use lowercase '.jpg' or it will complain that it doesn't know the format.
