+# Reducing Image File Size on Mac with ImageMagick
+
+This guide explains how to use ImageMagick to reduce the file size of a specific image, `PXL_20231206_193032116.jpg`, on a Mac to 2MB or less.
+
+## Prerequisites
+
+Ensure ImageMagick is installed on your Mac. If it's not installed, follow these steps:
+
+1. **Open Terminal:**
+   - Find Terminal in Applications under Utilities or use Spotlight to search for it.
+
+2. **Install Homebrew:** (Skip if already installed)
+   - To install Homebrew, a package manager for macOS, run:
+     ```bash
+     /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+     ```
+
+3. **Install ImageMagick:**
+   - After installing Homebrew, install ImageMagick with:
+     ```bash
+     brew install imagemagick
+     ```
+
+## Reducing Image File Size
+
+1. **Navigate to the Image Folder:**
+   - Change the directory to where `PXL_20231206_193032116.jpg` is located:
+     ```bash
+     cd /path/to/your/image/directory
+     ```
+
+2. **Reduce Image File Size:**
+   - **Option 1: Adjust Quality**
+     - Reduce the file size by decreasing the image quality. Start with a quality value of 85:
+       ```bash
+       convert PXL_20231206_193032116.jpg -quality 85 compressed.jpg
+       ```
+   - **Option 2: Resize Image**
+     - Decrease the file size by reducing the image dimensions, for example by 50%:
+       ```bash
+       convert PXL_20231206_193032116.jpg -resize 50% compressed.jpg
+       ```
+   - Replace `compressed.jpg` with your preferred new filename.
+
+3. **Verify File Size:**
+   - Check the size of the new file (e.g., `compressed.jpg`). If it's still over 2MB, further adjust the quality or resize percentage.
+
+4. **Replace Original Image (Optional):**
+   - To overwrite the original image, use the same file name for the output in the command.
+
+## Conclusion
+
+This guide helps you use ImageMagick on a Mac to reduce the file size of `PXL_20231206_193032116.jpg`, aiming for a target of 2MB or less.
