heic2jpg
This is an image conversion tool built on top of libheif (see https://github.com/strukturag/libheif/blob/master/examples/heif_convert.cc) to convert HEIC files to JPG.
Compatibility
The tool has been written for Ubuntu and tested on Python v3.5 and above but may be compatible with other versions of python too.
Dependencies
Requires python3 (mostly present by default).
Usage
The tool can be run as a Python script, e.g.:
python3 heic2jpg.py -d <data_dir> -o <out_dir> -m 1000000 -rec -v -resize 50% -quality 50%
It supports all arguments for the imagemagick convert tool, and additionally the following arguments:
-d, --data: Input file/directory
-o, --out: Output file/directory. Default: Same as input directory/file with .jpg extension.
-rec, --recursive: Recursively process subdirectories if input is a directory.
-v, --verbose: Increase verbosity.
-q, --quality: Quality of converted file (integer in [0, 100]). Default = 90.
Note that the tool only processes image files with extension .heic or .heif. All other unsupported files are copied over directly. If -rec is not specified, all subdirectories are copied directly to the output directory.
