Image Resizing/Compression Script

This is a bash script that resizes and/or compresses images. It was initially built to free up space on the server but can also be used to compress images to decrease load times and bandwidth usage. By default, it compresses images to 60% and resizes images to max 1200×1200 (keeping aspect ratio the same). You are able to compress or resize separately.


  • Make sure ImageMagik is installed (on cPanel: Software >> Install an RPM)
  • Upload/create a file called with the below code in it
  • Make file executable:chmod +x
  • Move to /usr/bin:mv /usr/bin/
#Script will take folder name as parameter
#Find all files
#Check if a file is image
    #If image then check if size is > 1200 width
        #If yes then resize/compress
files=`find $path -type f -exec file {} \; | awk -F: '{if ($2 ~ /image/) print $1}'`;

while read file; do
    owner=`ls -al "$file" | awk '{print $3}'`;
    group=`ls -al "$file" | awk '{print $4}'`;
    perms=`stat -c '%a' "$file"`;

    if [ "$option" == "resize" ]; then
        w=`identify "$file" | cut -f 3 -d ' ' | sed 's/x.*//'`;
        if [ $w -gt 1200 ]; then
            echo 'Resizing Image : '$file;
            mogrify -resize 1200x1200 "$file";
    if [ "$option" == "compress" ]; then
        echo 'Compressing Image : '$file;
        convert -quality 60 "$file" "$file";

    chown "$owner":"$group" "$file";
    chmod "$perms" "$file";
done <<< "$files"
