# 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.
