What is hidden text?

Hidden text refers to content that exists within a document but is not visible when the document is printed or displayed normally. This can occur in word processing software where certain text can be formatted to be hidden for various reasons, such as to include notes or comments that are not meant to be seen by all readers in a final version of a document. The formatting options typically allow users to control the visibility of text, enabling them to include information for editing or drafting without having it appear in the published or printed output.

In contrast, the other options may describe forms of text that have distinct meanings or implications. For instance, text that is not part of the document suggests that the information does not exist within the file at all. Inaccessible text in a PDF file refers to content that might be present but is not readable or viewable due to restrictions or format issues. Encrypted text for security purposes implies that the text is intentionally obscured through encryption to protect sensitive information. These distinctions clarify the unique nature of hidden text as being present but intentionally omitted from visible representation during standard viewing or printing processes.
