Convert .heic files to .jpg on linux (coming from an iOS11 device over USB)

convert.sh

# download release from github: https://github.com/monostream/tifig/releases and install at ~/tools/tifig
# then run these commands in the folder (just to keep things simple we normalize the file extension case before proceeding).

for f in *.HEIC; do mv "$f" "`echo $f | sed s/.HEIC/.heic/`"; done
for file in *.heic; do echo "~/tools/tifig -v -p $file ${file/%.heic/.jpg}"; done

The script will convert all HEIC files in the current directory to JPEG files. The first line of the script uses the mv command to rename all of the HEIC files to have a lowercase file extension. This is necessary because the tifig command only supports lowercase file extensions.

The second line of the script uses a for loop to iterate over all of the HEIC files in the current directory. For each file, the script echos the command that will be used to convert the file to JPEG. The command is:

~/tools/tifig -v -p $file ${file/%.heic/.jpg}

The ~/tools/tifig part of the command tells the script to use the tifig command that is installed in the ~/tools directory. The -v flag tells the tifig command to be verbose, so that it will print out more information about the conversion process. The -p flag tells the tifig command to preserve the EXIF metadata in the JPEG file. The $file part of the command tells the tifig command the name of the HEIC file to convert. The ${file/%.heic/.jpg} part of the command tells the tifig command to replace the file extension of the HEIC file with ".jpg".

To run the script, you can save it as a file called convert.sh and then run it from the command line. For example, if you are in the directory where the script is saved, you can run the script by typing the following command:

bash convert.sh

This will convert all of the HEIC files in the current directory to JPEG files.

@buragwitmo I believe this will be useful for you.
