Image Processing Script

A simple bash script to:

1. Remove all metadata from images
2. Reduce file size without quality loss
3. Add -processed suffix to filenames (optional)
4. Move processed files to a processed/ folder

Features

• Supports JPG, JPEG, PNG, GIF, BMP, TIFF, WebP
• Uses exiftool to strip metadata
• Uses jpegoptim for JPEG optimization
• Uses optipng for PNG optimization
• Uses convert (ImageMagick) for other formats
• Displays file size savings
• Optional --keep-name flag to preserve original filenames instead of appending -processed

Installation

1. Download the script to your preferred location, e.g.:

   curl -O https://example.com/image_process.sh

2. Make it executable:

   chmod +x image_process.sh

3. Move to a directory in your PATH:

   sudo mv image_process.sh /usr/local/bin/image_process

Alternative: Use ~/.local/bin

If you prefer a user-local installation without sudo, move the script to ~/.local/bin (ensure this directory is in your PATH):

mkdir -p ~/.local/bin
mv image_process.sh ~/.local/bin/image_process
chmod +x ~/.local/bin/image_process
export PATH="$HOME/.local/bin:$PATH"  # Add to ~/.bashrc or ~/.zshrc

Dependencies

Install required tools:

# Debian/Ubuntu
sudo apt install libimage-exiftool-perl jpegoptim optipng imagemagick

# RHEL/Fedora
sudo dnf install perl-Image-ExifTool jpegoptim optipng ImageMagick

# Arch Linux
sudo pacman -S perl-image-exiftool jpegoptim optipng imagemagick

Usage

Run the script in any directory containing images:

process_images [--keep-name]

Options

-k, --keep-name : Preserve the original filenames in the processed/ folder instead of appending -processed.

Behavior

• By default, files are renamed to originalname-processed.ext and saved in processed/.
• With --keep-name, files retain their original names in processed/.
• Example:
  • Default: IMG1234.jpg → processed/IMG1234-processed.jpg
  • Keep name: IMG1234.jpg → processed/IMG1234.jpg

Enjoy optimized, metadata-free images!
