What is PDF Security?

If you work with a large number of documents that contain sensitive or confidential data, you must pay special attention to PDF and documents security. Both storing and sending digital documents securely are challenges for any organization.

Password protection

One of the most basic and effective ways to secure a PDF is to add a password to it. This ensures that only those who know the password can open and view the contents of the file. When creating a password-protected PDF, you can specify whether the password is required to open the file, or if additional permissions, such as editing or printing, are also protected.


In addition to password protection, you can also encrypt a PDF to further secure its contents. Encryption uses a complex algorithm to scramble the data within the file, making it unreadable without a decryption key. This is an important step for sensitive documents such as financial statements or personal information.

Digital signatures

A digital signature is a way to verify the authenticity of a document and ensure that it hasn't been tampered with. By adding a digital signature to a PDF, you can confirm the identity of the person who created or approved the document, and that the contents of the file are the same as when it was signed.

Limiting access

Some PDF editors and viewers allow you to set permissions for a document, such as restricting who can view, print, or copy the contents of the file (specifically our online tool HelpRange can help you in that). This can be useful for preventing unauthorized access or sharing of sensitive information.

Keep your software up to date

PDF security vulnerabilities are regularly discovered and fixed by software vendors, so it's important to keep your PDF editor and viewer software up to date to ensure that your files are protected against the latest threats.

Use Trusted Software

Use a software from a reputable company that has a good track record of providing secure PDF software

A Few Words Of Summary

PDF security is a mandatory task for every business and organization. We need to take care of digital documents in the same way as those in traditional paper form, if not even more so.
