HEIC Converter

A small Windows/Mac/Linux program that converts iPhone HEIC photos to JPEG or PNG, in batches.

Download heic_converter.py

Pick one or many HEIC/HEIF photos and check which to convert.
Output as JPEG (adjustable quality) or PNG.
Optional size limit (1200, 1600, or 2048 px on the longest side).
Fixes phone rotation, saves to a folder or one zip, and never overwrites existing files.
Everything happens on your own computer. Photos are never uploaded.

How to run it

Install Python 3 from python.org. On Windows, accept the default options.
Open a terminal (Windows: type cmd in the Start menu) and install the two libraries it needs:
```
pip install pillow pillow-heif
```
Go to the folder where you saved the file and start it:
```
python heic_converter.py
```
Click Add HEIC Images, choose your settings, then Save Checked to Folder or Save as Zip.

On a Mac, if it says Tk is missing, run brew install python-tk. On Linux, install your distribution's python3-tk package.
