Why Do You Need to Mask Something in PDF?

There are numerous reasons why masking text in PDF documents can be essential. We've listed some of the most common reasons as to why you may need to mask text in a PDF file:

  • Protection of Sensitive Information: If your PDF documents contain confidential data such as personal details, financial information, or other content that should be shielded from unauthorised access, you may want to conceal this information to prevent it from falling into the wrong hands.
  • Error Correction: Making typos or spelling errors is very common, and can be a huge inconvenience when you've already saved your PDF file. Masking allows users to rectify these issues discreetly without altering the overall appearance of the document.
  • Compliance Requirements: Many industries are subject to regulatory standards regarding data privacy and security. Masking sensitive information helps organisations remain compliant with these regulations and avoid potential legal ramifications.
  • Presentation Purposes:  In presentations or reports, you might want to focus on specific parts of a document while temporarily hiding other sections to avoid distractions and keep the attention of your audience.
  • Selective Sharing: Sometimes, you might need to share a PDF file with someone who needs to see the majority of the document, but isn't authorised to view the more private or sensitive information within it. In these cases, you'll find it useful to obscure certain parts of the document that you don't want to share.
  • Anonymising Personal Data: When conducting research or data analysis, it can be necessary to conceal the identities of individuals while presenting research results and analysing patterns and trends.

What Information Should You Mask When Sharing?

When sharing PDF documents, it can be crucial to identify and mask sensitive information to safeguard privacy. By carefully assessing the content of your PDF documents and how they are going to be used or shared, you can determine which information requires masking to ensure privacy and security. Here are the most common types of information that you may want to mask within your documents:

Personal Details: Personally Identifiable Information (PII) is data that can be used to identify an individual, and it should be concealed when sharing a PDF file. This includes names, usernames, addresses, phone numbers, social security numbers, and email addresses. Also under this umbrella are things like passport numbers, driving license numbers, or government-issued identification numbers.

Financial Details: Needless to say, it's imperative to hide any financial information detailed within a PDF file when sharing it with others. Bank account numbers, credit card details, and financial statements should all be masked to prevent identity theft or fraud.

Confidential Business Information: Trade secrets, legal case information, or business strategies should also be redacted from your PDF files. This is important for your business to maintain an advantage over the prying eyes of competitors and protect any confidential plans or information.

Sensitive Corporate Information: It's important to protect the identities and information of the employees within a business as well as customer data. Things like employee names, payroll data, performance reviews and disciplinary actions should be hidden from any PDFs that you plan to share, as well as sensitive customer information.

Security Credentials: When sharing a PDF file, it's also crucial to ensure that you mask all passwords, encryption keys and access codes, as well as answers to security questions used for authentication and API keys.

FAQs about Masking Content in PDF

Can I Mask a Field in PDF?

Yes, you can - with UPDF, you can easily mask fields in your PDF files. Masking a form field in PDF is the same as masking text in PDF, and just go to the "Redact" feature and follow the simple steps in our user-friendly guide (detailed previously in this article) and you'll be able to conceal any information that you require within your PDF documents.

Can I Mask PDF Content Online for Free?

While some online tools claim to offer free PDF masking capabilities, they often provide only a rectangle shape to cover the text that you want to mask. This provides very limited functionality and does not guarantee secure redaction, as it can easily be removed with the right software. It's much more advisable to use offline tools like UPDF for a more comprehensive and reliable masking experience.

How to Mask Content in PDF with Adobe Acrobat?

Adobe Acrobat also offers redaction features for masking content in PDFs. Here's how you can redact data from a PDF document using Adobe:

1. First, launch the Adobe Acrobat Pro software and open the PDF file that you want to redact.

2. Next, click on "Tools" and then "Redact" from the options on the interface.

3. Click on "Mark for Redaction" then "Text & Images".

4. Select the text or images that you need to redact, then click "Apply". If you'd like to customise your PDF document, do this before selecting "Apply" - after editing, you can then apply the redaction that is required and save your PDF file.

The Adobe Acrobat software is very costly compared to UPDF, which provides an array of PDF editing features at a much more affordable price point. Adobe's pricing starts at $22.99 per month, whereas UPDF's prices start from only $35.99 per year - only 1/12 of Adobe's fee. UPDF also offers a one-time perpetual fee for as little as $55.99 which is incredible value for money, as this gives the user access to the software for life. You can check the full comparison between Acrobat and UPDF to get more information.
