PHP Download, Crop and Save Image in a Folder from URL

Download, Crop and save image in a specific directory is one of the most irritated task sometime I have to do. But as a web developer I got some skills to tackle this hectic task. 🙂

I have created a php script that download, crop and save image from url. I just have to pass image url in the input field, set dimensions and image will crop and save in the folder.

In this tutorial I am going to share the basic idea behind that code with you guys. If you are following my blog you people know that I write my blog post keeping PHP beginners in my mind. So lets start with basics. I will use some built-in image functions of PHP which are listed below.

Function	Description
imagecreatefromjpeg($filename)	Create a new image from url or file
imagejpeg($image, $to, $quality)	Output JPEG file from the given image
imagepng($image, $to, $quality, $filters)	Output or save PNG file from given image
imagegif($image, $to)	creates the GIF file
imagecropauto($image, $mode, $threshold, $color)	Automatically crops an image according to the given mode. Modes are IMG_CROP_DEFAULT, IMG_CROP_TRANSPARENT, IMG_CROP_BLACK, IMG_CROP_WHITE, IMG_CROP_SIDES, IMG_CROP_THRESHOLD
imagesx($image)	Return the width of the given image
imagesy($image)	Return the height of the given image
imagecrop($image, $rect)	Crops an image to the given rectangular area and returns the resulting image. The given image is not modified.
imagedestroy()	Free memory associated with image

I will be using following image throughout my examples.


<?php $image = imagecreatefromjpeg("https://www.wdb24.com/wp-content/uploads/2018/02/php-curl-get.jpg"); ?>

<?php $image = imagecreatefromjpeg("https://www.wdb24.com/wp-content/uploads/2018/02/php-curl-get.jpg"); ?>

Create JPEG:


<?php imagejpeg($image, "my-image-1.jpg");?>

<?php imagejpeg($image, "my-image-1.jpg");?>

Create PNG:


<?php imagepng($image, 'my-image-2.png'); ?>

<?php imagepng($image, 'my-image-2.png'); ?>

Create GIF:


<?php imagegif($image,'my-image-3.gif'); ?>

<?php imagegif($image,'my-image-3.gif'); ?>

Auto Crop Image:


<?php
	$cropImageAuto = imagecropauto($image, IMG_CROP_THRESHOLD, null, 16777215);
	imagejpeg($cropImageAuto, "my-image-4.jpg");	
?>

<?php

$cropImageAuto = imagecropauto($image, IMG_CROP_THRESHOLD, null, 16777215);

imagejpeg($cropImageAuto, "my-image-4.jpg");

Auto Crop Manually:


<?php

$image2 = imagecrop($image, ['x' => 150, 'y' => 60, 'width' => 400, 'height' => 300]);

if ($image2 !== FALSE) 
{
    imagejpeg($image2, 'crop-image.jpg');
    imagedestroy($image2);
}

imagedestroy($image);

?>
