You can use the imagecopyresampled
function in PHP to crop an image. Here's an example of how to use this function:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<?php // Load the image $image = imagecreatefromjpeg('original.jpg'); // Crop the image $cropped = imagecreatetruecolor(200, 200); imagecopyresampled($cropped, $image, 0, 0, 0, 0, 200, 200, imagesx($image), imagesy($image)); // Save the cropped image imagejpeg($cropped, 'cropped.jpg'); ?> |
This example will take an image called original.jpg
, crop it to 200x200 pixels, and save the result as cropped.jpg
.
You can also use the imagecopyresized
function to crop an image. This function works in a similar way to imagecopyresampled
, but it uses a faster algorithm that can result in lower quality images.

<?php // Load the image $image = imagecreatefromjpeg('original.jpg'); // Crop the image $cropped = imagecreatetruecolor(200, 200); imagecopyresized($cropped, $image, 0, 0, 0, 0, 200, 200, imagesx($image), imagesy($image)); // Save the cropped image imagejpeg($cropped, 'cropped.jpg'); ?> |
You can also use the imagecrop
function, which can automatically crop an image to a given width and height.
1 2 3 4 5 6 7 8 9 10 11 12 |
<?php // Load the image $image = imagecreatefromjpeg('original.jpg'); // Crop the image $cropped = imagecrop($image, ['x' => 0, 'y' => 0, 'width' => 200, 'height' => 200]); // Save the cropped image imagejpeg($cropped, 'cropped.jpg'); ?> |
This example will crop the top left corner of the image to 200x200 pixels. You can adjust the x
, y
, width
, and height
values to change the part of the image that is cropped.
