title: JPEG Optimization from PHP running on hosted accounts
body: <p>I am looking for a loss-less JPEG optimization tool that I can include in a PHP-based photo gallery software.</p>
  
  <p>I already checked the following question, but ruled out the tools mentioned there for reasons I'll explain below:</p>
  
  <p><a href="https://stackoverflow.com/questions/985725/tools-for-jpeg-optimization">Tools for JPEG optimization?</a></p>
  
  <p>The command line tools jpegtran and jpegoptim are not available in the average PHP hosting account. The web-based tools (www.smush.it, www.kraken.io) all have a limit of 1 MB for processed images.</p>
  
  <p>The 1 MB limit is a problem, because the gallery software delivers images based on browser-size and I also want to support Full HD and even larger displays. Depending on content, photos prepared for such resolutions can get larger than 1 MB.</p>
  
  <p>Any hints on a solution are appreciated!</p>
