How to Unlock a PDF File For Editing

When you set a password for a document, you’re required to enter it in every time you want to work with it.

But a password is highly useful when dealing with confidential and sensitive information. Say, if you store documents that aren't allowed to be disclosed to other people, or when you send them and want to be sure that they will be read by the right person - then it's definitely better to protect them with a password.

However, you still need to pass this security feature every time you want to access your document. This usually doesn't pose a problem if you don't use the file too often. But if you're using this document often, the need for constant authorization can get annoying.

So, what do you have to do to keep your security while getting rid of unnecessary repetitive actions? AltoUnlockPDF is how you can remove PDF document protection.
