The imagejpeg() function is an inbuilt function in PHP which is used to display image to browser or file. The main use of this function is to view an image in the browser, convert any other image type to JPEG and altering the quality of the image.

Syntax:

Parameters: This function accepts three parameters as mentioned above and described below:

  • $image: It specifies the image resource to work on.
  • $to (Optional): It specifies the path to save the file to.
  • $quality (Optional): It specifies the quality of the image.
