Limitations of Free Online PDF Optimizer

Online optimization may not be the ideal route to use when optimizing your PDF files because:

  • While many online PDF optimizer tools are offered as "free", many of the features may be missing until you buy them.
  • Most online PDF optimization tools require you to register, meaning you have to keep logging in when you are optimizing or using online tools.
  • Some of the processes are so complex that you may need extra resources or an advanced knowledge of PDF editing to understand how to properly optimize your document.
  • Most people are afraid of working online with sensitive or confidential data because it could be breached. Online optimization does not give you 100% assurance that your file is safe. Therefore, there is a safety risk when you use online tools.
  • There is also usually a limit to the amount of data you can process online and the quality of the output.
  • An internet connection is required to use any of these programs.
