If you want to remove password from PDF on Windows 10 or Mac, you can use Google Chrome to do it. In case you want to do this via Adobe Acrobat DC, you’ll have to purchase the full version of Adobe Acrobat DC. The service will cost you Rs. 1,014 per month if you commit to an annual contract or if you want to use it for a month or two, you can pay Rs. 1,691 per month. Once that’s done, follow these steps:

1. Open the PDF file in Adobe Acrobat Pro DC and enter the password to unlock the file.
2. After the file is open, click on the Lock icon on the left and under Security Settings, click on Permission Details.
3. Once you do that, click on Security > set Security Method to No Security and click OK to remove the password.
4. Next, click File > Save and from the next time you open this PDF file, you won’t be asked to enter a password.
