Remove PDF read-only - how to make the file changeable

The Portable Document Format (PDF) was first released in 1993 and is an independent file format for documents. You can make a PDF read-only with a password, so that no more changes can be made to the file. You can remove the read-only protection in a few steps even without a password.

How to remove write protection from a PDF?

How to remove write protection depends on whether you have the required password or not.

1. Install and launch PDFFill PDF Tools.
2. Now select the third item "Encrypt and Decrypt Options". A window will open where you select the file you want to unlock.
3. You will be asked for the password. Enter it and save the file again, but this time without write protection using "Decript As".
4. If you don't know the password of the read-only file, there are several ways to decrypt it.
5. Using PDFFill Tools, you can format the PDF to a non-read-only file via a virtual printer.
6. Another option is to use an online PDF converter. Dieser versucht die Datei zu entsperren und bietet Ihnen diese danach wieder zum Download an.
7. Sie können auch ein Programm verwenden, das extra für einen solchen Fall entwickelt wurde. Hierfür gibt es den PDF Password Remover.
