Disadvantages of Removing Unknown Password from PDF Online Free

While online tools like iLovePDF can be very useful in a bind, they may not be a good long-term solution especially if you will be unlocking many documents. The following are some of the main disadvantages of using an online tool to unlock a PDF document;

  • The first thing you need to be concerned with when using an online tool is the safety of the file you are unlocking. Most of these sites offer little or no security guarantee for the documents or their content.
  • To use these tools, you will also need to be connected to the internet, which may not always be possible.
  • Very few online tools will allow you to unlock more than one file at the same time and most that claim they can may not be able to unlock all the documents.
  • These online tools are also less stable when compared to desktop solutions. This means that while they can claim to unlock any document, many fail to even detect the uploaded document or they can claim the decryption is successful, only for you to find the document is still locked.

In conclusion, it is better to use aJoysoft PDF Password Remover to help you remove unknown password from PDF document. Try it now.
