4 Ways PDF Format Provides Document Security

PDF editors are dedicated tools for users to view, edit, merge, combine and comment on PDF files. While PDF editors have made it easy to alter PDF documents, it’s also important to make sure content within your PDFs is safe while editing.

In this article, we’ll cover four ways PDF formats ensure document security and how you can use them. If you’re wondering why the fuss about PDF security, this article will show you why you need to secure your documents as you share and edit over the web.

PDF Encryption

PDF encryption involves installing security features that prevent access from unauthorized users to your PDF files. The best Use a PDF editor allow you to encrypt your file, and only those users with the decryption key can access or edit the file.

PDF encryption limits file sharing and offers full content protection within PDF files. Content within an encrypted PDF is unreadable and thus impossible to edit. As a result, there’s no way unauthorized personnel can open or copy your files unless they’ve got the decryption key.

Encrypting PDF documents bearing confidential information such as business contracts, government legislation, or fillable forms is advisable. Note that if you encrypt PDF files with passwords alone, anyone can easily use password recovery programs to remove passwords and make changes.

PDF Password Protection

PDF password protection includes the use of sets of characters to encrypt PDF documents. Most online PDF editors let you add passwords to protect your files and limit PDF access to users with the right password.

Although password protection is easy to implement, it is not entirely safe. This will work if you need to install basic PDF security, but some PDF file editors install password recovery functions in case of loss.

So, encourage users to use strong passwords (including numbers, letters, and characters). For improved protection, use different passwords for several files and manage the lists of passwords with a password manager.

PDF Copy Protection

PDF copy protection is another utility tool that offers protection against indiscriminate copying of PDF files. It is a vital asset for publishers, project management teams, corporate eLearning trainers, and research outlets.

To prevent the unauthorized conversion of your PDFs to other document formats, you can activate the copy protection tools within your PDF file editor.

These copy controls let you grant access, revoke permissions, or limit how far users can operate with your PDF files. This security feature restricts functions like copying, pasting, screen grabbing, modifying, and printing PDF files.

While this tool works seamlessly to keep your PDF safe, it also ensures you can share protected documents fast and securely.

PDF Digital Rights Management

PDF Digital Rights Management (DRM) is a system of tools designed to secure and control the distribution and use of PDF files. These technologies allow you to set restrictions, track user activity, and control editing options for all shared parties.

When you lock a file, using DRM controls ensure that only users with a proper license can access it. DRM protection will secure your confidential files from illegal copying, watermark removal, and unauthorized redistribution.

DRM controls precede copyright protection and help content creators determine how people can assess and use media and PDF document files when released to the public. It also ascribes ownership rights to the creator and protects sensitive information within PDF files.

Why do you need to protect your documents?

Now that you know the different ways that PDF files provide document security, perhaps you’re still curious to know why this article advocates for document protection. You’ll need to secure your PDF documents for the following reasons:

To stop indiscriminate PDF sharing

Some work functions may require you to share your PDF files with others, but you’ll need to prevent them from sharing with other unauthorized persons. When you secure your documents with passwords or encryption keys, you’ll be able to keep your files in the right hands only.

PDF files are incredibly easy to share and circulate widely. It’s crucial to install some basic security to limit how you distribute files.

To Limit Access

When you lock a PDF file, you restrict user access and implement confidentiality measures to keep your PDF safe. DRM controls and passwords prevent your PDF files from unauthorized access because users won’t be able to share with just anyone.

Government agencies need to secure information shared as PDFs and limit who can view or edit PDF file online. Limiting access will vary within organizations, as some people need the authorization to view only, while others require authorization to make comments.

For Copyright Protection

Another important reason to secure your PDF documents is to secure intellectual property rights to the original author. Copyright law confers legal rights of ownership to the original author and prevents indiscriminate copying by others.

You can protect content within your PDF files even as you create content by encrypting with passwords or decryption keys. This way, no one can access, share, or claim ownership of your work without your permission.

To Preserve Content Integrity

Content integrity becomes essential when the information within a document will be shared, edited, and received accurately. This often applies to PDF fillable forms, contracts, and payment instructions.

Where you add or revise comments within a document, it’s vital to preserve content integrity by securing PDF documents. You can do this by adding encryption keys or passwords.

To Prevent Caching on the Web

When using an online PDF editor to view or edit PDF, users with access can save the file to their device. Because it can cache web pages on the user’s storage, now it’s easier for them to recover or access the files off the web.

The best way to avoid caching is to disable this feature on your device browsers and online PDF editors. Then, you can preserve your document security and can edit files online with less risk.


Beyond the ease of using PDFs for sharing important information, securing the content within PDFs is more relevant than ever. As you use PDF file editors online, you’ll need to understand the reasons for locking PDF files so you can use ‌ security features.

Some PDF documents require password protection, while others, such as business emails and payment options. When you know why you should secure your documents, you’re one step ahead on how to do it.
