4 Methods to Remove Encryption from PDF

It may be an irritating experience to lose access to a file when you need it suddenly, and this is particularly true in the case of PDF files due to how they are constructed, and the fact that they can be locked with a password. When it comes to your attempt to remove encryption from PDF or free up space in a PDF file that has been restricted, there are a few tools you can use.

When it comes to removing encryptions imposed on PDF files and then modifying them, aJoysoft PDF Password Remover and UPDF are among the most potent solutions currently accessible - one unlocks it and the other helps you edit and perform other actions. When you use these tools, the procedure of eliminating encryption from PDF files is quite simple. You can remove any constraints at any time by just pressing a single button.

aJoysoft PDF Password Remover can let you print, copy, or change PDF files without your knowing the owner or master password, which is also what we refer to as Permissions passwords above. As mentioned, as long as the original password is known, this software can unlock user-or open-password-protected PDFs.

Step 2: Free Yourself from the Chains of Password Protection

Next, select "Remove Password" to wipe off all limitations. Select a destination folder to store the imported, unlocked files when requested.
