How to protect a PDF file with a password
Ensure that your online PDF documents remain safe
How many e-mails have you received this week? And how many of them contained a PDF document as an attachment? It's safe to say that most of us get to process PDF files at least once a week - at the bare minimum.
It should come as no surprise that since the 1990s, the use of PDF documents has grown in great popularity and PDFs have become one of the world´s most widely used formats distributed electronically every day. In particular, PDFs are extremely useful when being shared across multiple platforms and devices.
Undeniably, a PDF document is easy-to-read, it doesn´'t change format after opening, and it ´s supported by any operating system. Most importantly, you can protect your PDF file from copying and editing in order to prevent any misuse or mishandling of information.
Why do you set a password on your smartphone? The reason for protecting your PDF document with a password is equally important: you want to protect data and information that could otherwise be accessible by unauthorized users.
Protecting PDF files with a password comes in handy, especially when:
- You have to send documents via email containing customer´s or client´s information, contracts & agreements, forms, etc.
- You want to prevent extracting any personal or sensitive data
- You want to prevent other users from reproducing, printing or sharing your PDF document.
- You don´t want unauthorized users to open or read the content of the shared document.
How to make password protected PDFs
iLovePDF has developed a free online tool to help encrypt PDFs with a password. You can restrict editing from any PDF file and ensure that only users - with the right password/permission - can access shared documents.

Create an unbreakable PDF password
Now that you know how to add a password to your PDF file, you should consider what combinations to use. If you don'´t want to make it to the list of the top 100 worst passwords of 2019, you should follow the same old advice of having a “strong password.”
With all data breaches and leaks we hear about on a daily basis, it should be an especially crucial decision when managing files that contain sensitive data that are transferred electronically between devices.
Eliminate using your personal data and names that can be easily hacked. Make your PDF password long. Include combinations of letters, numbers, and symbols in a total length of at least 12+ characters.
Use your favorite memory or event with a combination of symbols and transform it into an easy-to-remember, hard-to-crack PDF password. Let your imagination flow and use the keyboard layout to craft a unique PDF password.
Despite countless warnings from experts and hackers themselves, there are still millions of people trying to protect their sensitive data and files with completely unprotected password combinations.
For the love of PDFs, stay away from the same variations of the worst passwords on the internet: 123456, password, 123456789, 111111, qwerty, Starwars, abc123, login...
Remember, you should always consider protecting PDF files from unauthorized access and distribution when you work with sensitive documents and share them online.
Take advantage of online tools such as iLovePDF that enable you - among many other features - to add a password to any PDF document in just a few seconds. And finally, make sure you use a strong and unique password combination.
