If you have a file with private or important information, adding a password is the best way to keep it safe. This stops people from opening your document without your permission or making changes to it.
While many people look for free ways to do this, you also want a tool that is safe and reliable. **JOPDF** is a great choice because it is a professional, “lightweight” (fast and small) program for your computer. It gives you two main ways to protect your files:
- Open Password: Use this if you want to stop people from even looking at the file without the secret code.
- Permission Password: Use this if you don’t mind people reading the file, but you want to stop them from changing the text, copying it, or printing it out.
