Tips for Password-Protecting Your PDF Files Across Platforms.

Easy Ways Put a Password on a PDF File
It is natural to want to share a confidential document with a client or colleague and not want any prying eyes to see its contents.

The best way to go about it is to convert that doc into a PDF file and protect its contents with a password. PDF is an excellent format for many reasons.

Besides its ability to carry both texts and images, you can also alter/edit its content without leaving behind a digital footprint.

And for the icing on the cake, password protection in PDF files are platform-independent.  That is to say; a recipient can decrypt a PDF encrypted in Windows using any other operating systems like Android, MAC, Android or platforms like email.

You must not have the same software on both ends.

The Two types To Passwords for PDF

You can password protect your PDF documents in two ways – by adding an owner password or a user password. 

The latter password protection is helpful if you wish to change permission settings, e.g., copying or printing. And the open/user password gives access to the PDF.

But there's no need to set an owner password because it is easy to bypass. For example, a user can still easily copy any info they need on the document by capturing screenshots and checking the details with an OCR reader.

So, in this case, we are shedding more light on the user password or the passkey needed to open a PDF. Here's how to password-protect your PDF docs across different platforms.

Put a password to PDF across different platforms

MacOS 

If you use macOS, then you have at your disposal the simplest way to encrypt a PDF. MAC has a built-in Preview which allows you to open PDF files.

Once your doc is open, click on the 'File' button on the menu bar and then click on 'Export.'  You will see a box before 'Encrypt' with space for password popping up underneath.

Come up with an alpha-numeric secret word and click on 'Save' have you a new file saved in 128-bit RC4 encryption.

Note; your old file remains unprotected, only the original file gets password protected.

 Windows 

Most Windows users use Adobe Acrobat to protect PDF files. However, it limits you to only a few PDF files and requests some fees moving forward.

But you can always try free software before spending in the skies, and still password-safeguard your PDFs.

PDFmate is an excellent example of free desktop software for windows.

IOS

Regrettably, there's no free method or tool to encode PDF in iOS – you'll need to pay some fee just like in most great iOS apps. But if your goal is to protect no matter the price, you can try an app known as Pages from Apple. 

A $10 fee gives you access to lots of options, including PDF password protection. But we can still be of help if you want to do it free; try using our online service.

Android

Though Adobe Acrobat's app for Android doesn't offer a password protection option, you can still protect your PDF docs with free apps from Google Play like the PDF Utility. 

After installing the app, like you'd do with any other, launch it, open password protection, import from your file manager the PDF doc you want to be protected.

The app gives two password options; user password and owner password. And like we'd agreed earlier, then the owner password restricts document permissions while the user password restricts access to the file.

To stay safe, use the same password for both, and apply the saved changes.

Online Service 
While the internet offers multiple tools that can password-protect a PDF, some of them are not as safe as you think. Find out if the service provider uses https, and whether or not they store your PDF file on their server

Https is the most secure. And you don't want you files stored on a site for privacy purposes, or you are missing the whole point of protecting your files.

Ensure you use a legitimate site where you won't risk having your critical business documents stolen and circulating the dark market for sale to the highest bidder.

Final thoughts.

When protecting your files, do not forget to use strong alpha-numerical passwords to make the more impenetrable. Because PDFs are not so safe, you want to ensure your password beats any brute force attack attempts.
