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:

Open Terminal:
- Find Terminal in Applications under Utilities or use Spotlight to search for it.

Install Homebrew: (Skip if already installed)

To install Homebrew, a package manager for macOS, run:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install ImageMagick:
- After installing Homebrew, install ImageMagick with:
```
brew install imagemagick
```

Navigate to the Image Folder:
- Change the directory to where PXL_20231206_193032116.jpg is located:
```
cd /path/to/your/image/directory
```
Reduce Image File Size:
- Option 1: Adjust Quality
  - Reduce the file size by decreasing the image quality. Start with a quality value of 85:
```
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%:
```
convert PXL_20231206_193032116.jpg -resize 50% compressed.jpg
```
- Replace compressed.jpg with your preferred new filename.
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.
Replace Original Image (Optional):
- To overwrite the original image, use the same file name for the output in the command.
