First, you can change font type (e.g., switch from

In addition to using different font types, you can change the PDF font size. This can make the text 

, as you can enlarge letters that are too small. Also, resizing letters is a much easier way to improve a document’s readability instead of using complex methods, such as 

 or kerning, to adjust PDF font settings.

Decorative fonts can make your text look more interesting, sophisticated, and polished. However, overusing them can also make your documents look more 

informal and casual and, therefore, less professional

Even if your file is not official (e.g., a government form), overusing decorative fonts can also

. The reason for this is that letters can take on weird shapes because of all the curves and decorative elements.

Some readers may be unable to open or render your new font correctly after changing it. To prevent this, you can flatten your PDF file. This will combine all different layers into one, ensuring that any reader can 

open and display the PDF text in its original form

, regardless of the manufacturer or operating system.

This will also facilitate the sharing process, as merging layers can shrink PDFs. Still, as flattening is one of the ways to make your PDFs non-editable, we recommend making a copy of your original file before doing so.

and is a common practice for legal papers, business files, and contracts. In addition to these advantages, securing Word files with passwords also comes with certain downsides if not done correctly (e.g., weak passwords can be breached).

Therefore, it is crucial to know how to properly protect a Word file with a password, and when password-protecting PDF files using designated tools like pdf.net is smarter than using Word ones.

There are two types of password protection in Microsoft Word: passwords to open, which restrict access to the file, and passwords to modify, which prevent unauthorized changes and saving.

 on both Windows and Mac directly through Microsoft Word by selecting 

, as many data protection frameworks require privacy-by-design measures.

, but recovery is difficult if forgotten—making password management tools or backup copies essential.

, and pdf.net allows for encryption, complex passwords, and additional restrictions such as blocking printing, copying, and editing.

, both of which are available on all versions of the program. However, it’s worth noting that older versions, like Office 2007 and 2010, use 128-bit AES encryption, while Office 2016 and later rely on 256-bit AES encryption combined with 

As for types of passwords themselves, the difference is simple: open passwords restrict Word document access, and modify passwords only alter Word file permissions, limiting editing and formatting.

Now, let’s dig a bit deeper into their main differences:

How to Password-Protect a Word Document on Windows

You can password-protect a Word document on Windows by opening the file, finding the password-protection option, and setting the password. Although the overall process is similar on all versions of Word, some steps may differ, so keep that in mind if you’re using a version other than Microsoft Word 2016.

Let’s take a detailed look at these steps:

Find the document you want to protect and double-click it to open it.

Click the File menu in the top-left corner

 to manage editing and formatting permissions.


Choose Protect Document and select Encrypt with Password.

Save the changes by clicking the Save icon in the upper-left corner.

Let’s see the benefits of Word password protection in greater detail:

Restricting access to Word protects your documents from

Additionally, you can password-protect multiple files by creating a different password for each document, which allows you to 

manage access for different people and files individually

You can password-protect documents containing sensitive information to

If your competitors find details about this, they may use it for their own development, 

. Similarly, hackers may steal your valuable data and sell it to other companies, which can also endanger your business.

As password-protecting a Word document restricts access, it automatically limits the opportunity to modify such a file. This means that your information is not only safe from copying or stealing 

Of course, this is important because some documents may contain data that users must not alter in any way. For instance, some factory machines may be dangerous if not used correctly, and the service manual can be the only source for safe use. So, before sharing a Word document, you can password-protect it to 

ensure that all instructions remain intact

Due to the rise of technology, many countries, unions, and companies have proposed safety acts to protect people’s
