How to Use Whiteout to Erase Text in PDF

PDF files are made to have a fixed layout and formatted to be compatible to any computer, however, editing and erasing words from a PDF file can be a little tricky since it was not meant to be fluid, especially if you do not have any knowledge or tools.

What is whiteout?

By definition, whiteout means to hide, clear or erase any information on a PDF file. The term whiteout originated from the act of correcting written mistakes using correction fluid or a “white out.” This term was also known first on paper as “white correction fluid” or “whited out” when a mistake in typing or writing is to be removed.

Correction fluid or white-out is a white fluid applied to a paper to cover the mistakes made in the document, which will be written over once dry. This was how editing was done back in the day where there were still no computers or software available, hence, the term whiteout adapted until this day and is also now used in PDF editing to erase words or phrases on the PDF file.

History of whiteout and where the term came from

Before word applications, online documents or computers were generated, typewritten files and handwritten documents were passed back and forth and changed according to agreements. With small changes being applied to these documents, a physical eraser for these documents is required. With this need in mind, the liquid paper a.k.a. white correction fluid was created.

According to Wikipedia, American typist, Bette Nesmith created the first white correction fluid (liquid paper) back in 1956 which was mainly used to correct mistakes from typewriting. It was a product of the need for Nesmith as she used to make a lot of mistakes as a typist. The first liquid paper was then called “Mistake Out” and was distributed in small bottles. Years later it was bought by a bigger company, renamed into “Liquid paper” or “Whiteout” and now adapted to the digital world with the same purpose – erasing the mistakes on the typed document.
