Have you ever open a PDF format file to print, but the file showing a printing error, printing has been disabled, or you get an output of whole black/ white document from your printer. Most probably that the PDF file is being protected.
Advanced PDF Pro version software has a special function allows user to create password protection, copy protection, and printing protection so that another user cannot access to make a duplicate copy of the file either in soft copy or in hard copy version.
For online Geek, there is a way to unlock these protections.
Using a web service known as FreeMyPDF can help you to unlock protected PDF file as mentioned above. Just upload your file and you will get your new unlocked PDF file without restrictions.
However, this service only works for PDFs that you can open and read without any 3rd party plugins included. This web service cannot unlock PDFs that required a password to be opened. Since it is a web service, avoid uploading important private file especially your confidential PDF files.
Overall, no signup is required and it’s free to use!
