How to reduce the image size without losing quality in PHP [closed]

Question

I am trying to develop an image-based web site. I am really confused about the best image type for faster page loading speeds and best compression practices. Please advise me on the best way to compress image sizes.

Answer 1

If you are looking to reduce the size using coding itself, you can follow this code in php.

<?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); 

This is just a php function that passes the source image ( i.e., $source_img ), destination image ( $destination_img ) and quality for the image that will take to compress ( i.e., 90 ).

$info = getimagesize($source); 

The getimagesize() function is used to find the size of any given image file and return the dimensions along with the file type.
