Compress Image Size While uploading in Codeigniter

rajamohan · March 2023

Image compression is very helpful to reduce the size of the image. In the image compress functionality, the file size is reduced before upload.

The compressImage() is a custom function that helps to compress and save image on the server using PHP. This function accepts the following parameters and returns the compressed image.

*file_name - An image file source to compress size.
An image file source to compress size.
$file_path – Server path to save the compressed image.
$quality - An image file source to compress size.

Code:

function compress_image($file_name, $file_path, $quality) {

$imgInfo = getimagesize($tempPath);

$mime = $imgInfo['mime'];

// Create a new image from file

switch($mime) {

case 'image/jpeg':

$image = imagecreatefromjpeg($tempPath);

break;

case 'image/png':

$image = imagecreatefrompng($tempPath);

break;

case 'image/gif':

$image = imagecreatefromgif($tempPath);

break;

default:

$image = imagecreatefromjpeg($tempPath);

}

// Save image imagejpeg($image, $originalPath, $quality);

// Return compressed image

return $originalPath;

}

Get the Image from the form data using the html form.

if(isset($_POST["submit"])){ 
        if(!empty($_FILES["image"]["name"])) { 
        $fileName = $_FILES["image"]["name"]); 
         $uploadPath = 'uploads/user'
        $imageUploadPath = $uploadPath . $fileName; 
    
            $imageTemp = $_FILES["image"]["tmp_name"];              
            // Compress size and upload image 
            $compressedImage = compressImage($imageTemp, $imageUploadPath, 75); 
            if($compressedImage){ 
                $compressedImageSize = filesize($compressedImage); 
                $compressedImageSize = convert_filesize($compressedImageSize);     
               
            }else{ 
                $statusMsg = "Image compress failed!"; 
            } 
       
   
}
