Have you ever been in such a situation: you need to send a PDF file but don't want to share any private information within this document? Do you know how to fix this issue? In fact, there are many useful methods to help you hide those contents from being checked by others, among which we suggest whiteout. However, do you know how to white out on PDF?

What Does White Out Mean?

When you make a whiteout on a PDF file, it usually refers to erasing specific content in your document with white paint. The white-out feature is often used to correct mistakes in your file or conceal confidential information from being unveiled. Using a white-out effect over text or image content can better protect your private data, such as bank info, address, contact details, etc.

Whiteout is an ideal feature when you need to cover up text in a PDF file. It's irreversible and unchangeable, and no technology is available to revert to the original content. By doing so, you can cover all sensitive information safely.
