## Setup Instructions
### Prerequisites
Make sure you have ImageMagick installed. You can check if it's installed by running:
```bash
convert -version
```
If not installed, you can install it using:

```
- **Windows**:
Download and install from the [ImageMagick website](https://imagemagick.org/script/download.php).
### Project Setup
1. **Clone the repository**:
```bash
git clone https://github.com/yourusername/image-converter.git
cd image-converter
```
2. **Make the script executable**:
```bash
chmod +x convert_images.sh
```
3. **Add an alias to your shell configuration file**:
```bash
echo "alias convert='~/path_to_your_script_directory/convert_images.sh'" >> ~/.zshrc
source ~/.zshrc
```
Replace `~/path_to_your_script_directory` with the actual path where you cloned the repository.
## Usage
To convert a WEBP or HEIC file to PNG and JPG, use the following command:
```bash
convert filename.webp
```
or
```bash
convert filename.heic
```
The converted files will be saved in `~/Pictures/Converted`.
