How to Reduce or Compress Image File Size while Uploading Using PHP code?
It is a quite common process to upload images on the websites dynamically. However, while you upload the image with large file size in a website, it is likely to take more time to load. This necessitates the developer to write down the code to decrease the file size of image while dynamically uploading the image to the website. With the help of PHP coding, it is possible to reduce the size of files of uploaded images when they are loading. Definitely, you would have to compromise with the image quality i.e. is the file size has to be reduced.
Below is the Code to reduce file size for the image:
<?php
function compress($source, $destination, $quality) {
$info = getimagesize($source);
if ($info['mime'] == 'image/jpeg')
$image = imagecreatefromjpeg($source);
elseif ($info['mime'] == 'image/gif')
$image = imagecreatefromgif($source);
elseif ($info['mime'] == 'image/png')
$image = imagecreatefrompng($source);
imagejpeg($image, $destination, $quality);
return $destination;
}
$source_img = 'source.jpg';
$destination_img = 'destination .jpg';
$d = compress($source_img, $destination_img, 90);
?>
$d = compress($source_img, $destination_img, 90);
PHP function is used in the code that will pass the source image, destination image and quality for the image that takes to compress.
$info = getimagesize($source);
The getimagesize() function is also used to know the size of given image file and to return the dimensions including the file type.
Example:
$info = getimagesize($source); print_r($info);
Output:
Array ( [0] => 1280 [1] => 768 [2] => 2 [3] => width="1280" height="768" [bits] => 8 [channels] => 3 [mime] => image/jpeg )
$image = imagecreatefromjpeg($source); $image = imagecreatefromgif($source); $image = imagecreatefrompng($source);
All the functions used in the coding are intended to make a new image from the given URL or file. Those functions are meant for returning an image identifier indicating the image acquired from the given file name.
imagejpeg($image, $destination, $quality);
The imagejpeg() function is added in the code to make a JPEG file from the provided image.
Syntax: imagejpeg ( $source_image, $destination_image, $quality )
Quality ($quality): Quality is optional that range from 0 representing the worst quality and smaller file to hundred representing the best quality and biggest file. The range75 is considered as the default.
Note:
The GD library is utilized for creating dynamic image. GD library is used to create JPG, PNG or GIF. This is more essential to run every image creation function in PHP language. When your server is not compatible with GD library, then the complete functionality associated with the image creation won’t work out.
Here is the Complete code to reduce the image file size using PHP:
<?php
$name = ''; $type = ''; $size = ''; $error = '';
function compress_image($source_url, $destination_url, $quality) {
$info = getimagesize($source_url);
if ($info['mime'] == 'image/jpeg')
$image = imagecreatefromjpeg($source_url);
elseif ($info['mime'] == 'image/gif')
$image = imagecreatefromgif($source_url);
elseif ($info['mime'] == 'image/png')
$image = imagecreatefrompng($source_url);
imagejpeg($image, $destination_url, $quality);
return $destination_url;
}
if ($_POST) {
if ($_FILES["file"]["error"] > 0) {
$error = $_FILES["file"]["error"];
}
else if (($_FILES["file"]["type"] == "image/gif") ||
($_FILES["file"]["type"] == "image/jpeg") ||
($_FILES["file"]["type"] == "image/png") ||
($_FILES["file"]["type"] == "image/pjpeg")) {
$url = 'C:/Users/admin/Downloads/compressed.jpg';
$filename = compress_image($_FILES["file"]["tmp_name"], $url, 80);
}else {
$error = "Uploaded image should be jpg or gif or png";
}
}
?>
