  • If your PDF file is locked with password to open, it will require you to enter the password.

My test:

The speed to access the official site is quick. But it is not easy to find the function of unlock in the homepage. It will be better if the searching bar is displayed in the homepage. The speed to upload a PDF file is fast. And it offers several options for you to save the unprotected document. But if you upload a PDF file locked with user password, you will be asked to enter the correct possword. I do not recommend that you choose this tool if you forgot the password to open the document.

My test:

It really has an easy-to-use interface. In the beginning, I uploaded a PDF file protected with user password. It requires me to enter the correct password. So it is not workable when you lost or forgot the password. The second time, I want to upload a PDF file protected with owner password. But it asks me to start a free trial and pops up a window to creat an account. After that, it pops up the purchase page. In a word, it is not a good experience.
