Overview

Too many services still do not support HEIC formatted images. Install ImageMagick and run this command to convert them all.

Technical Details

Add this to your ~/.bash_profile so that we don’t have to memorize all the options:

alias convertallheic='for f in *.HEIC *.heic; do magick "$f" -quality 100% "$f.jpg"; done'

Source the file to load it. You don’t have to do this all the time, terminals will typically load aliases on startup:

source ~/.bash_profile

Execute in a directory full of HEIC images:

convertallheic

Validate it worked:
