# Image Converter

This project provides a script to convert WEBP and HEIC images to PNG and JPG formats using ImageMagick.

## 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:

• macOS:

  brew install imagemagick
  

• Ubuntu:

  sudo apt-get update
  sudo apt-get install imagemagick
  

• Windows: Download and install from the ImageMagick website.

Project Setup

1. Clone the repository:

   git clone https://github.com/yourusername/image-converter.git
   cd image-converter
   

2. Make the script executable:

   chmod +x convert_images.sh
   

3. Add an alias to your shell configuration file:

   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:

convert filename.webp

or

convert filename.heic

The converted files will be saved in ~/Pictures/Converted.

2. **convert_images.sh**:
```bash
#!/bin/bash

# Check if the magick command is available
if ! command -v magick &> /dev/null; then
    echo "ImageMagick is not installed or not in your PATH."
    exit 1
fi

# Get the input file from the command line argument
input_file=$1

# Check if input file is provided
if [ -z "$input_file" ]; then
    echo "Error: No input file specified. Usage: convert file1.webp or convert file1.heic"
    exit 1
fi

# Extract the base name and extension of the input file
base_name=$(basename "$input_file" | cut -d. -f1)
extension=$(basename "$input_file" | cut -d. -f2)

# Define the output directory
output_dir="$HOME/Pictures/Converted"

# Check if the output directory exists, create if it does not
if [ ! -d "$output_dir" ]; then
    mkdir -p "$output_dir"
fi

# Function to convert images
convert_images() {
    local input_file=$1
    local base_name=$2
    local output_dir=$3

    # Convert to PNG
    magick "$input_file" "$output_dir/${base_name}.png"
    echo "Converted $input_file to $output_dir/${base_name}.png"

    # Convert to JPG
    magick "$input_file" "$output_dir/${base_name}.jpg"
    echo "Converted $input_file to $output_dir/${base_name}.jpg"
}

# Check the file extension and convert if it is .webp or .heic
if [ "$extension" = "webp" ] || [ "$extension" = "heic" ]; then
    convert_images "$input_file" "$base_name" "$output_dir"
else
    echo "Error: The file must be either .webp or .heic."
    exit 1
