Change a png to a jpg - Anthony 14/6/2008

Any transparency is lost in this case as jpg does not support transparency. You can change from different formats by changing the imagecreatefrompng and the imagejpeg functions.

  1. <?php
  2. // Create a new image in the memory from the file 
  3. $png_image = imagecreatefrompng( "input.png" );
  4. // Save the image as output.jpg
  5. imagejpeg( $png_image, "output.jpg" );
  6. // Clear the memory of the tempory image 
  7. imagedestroy( $png_image );
  8. ?>
