Annotating the PDF: The Basics

You can be a reader or an editor, and in both cases, annotating a PDF can be useful for you. If you have a fiction, scientific literature, or a student book, you may leave the insights right in your PDF annotated file or highlight the most important information. The next time you open it, a PDF with annotations will be there.

Another case is when somebody asks you to check their work or article and sends it in PDF. You don’t want to change anything without the author’s permission, so you only leave the corrections and comments where needed. This person will see them when opening it on their device.

So, Windows PDF annotation can be used in diverse cases. It is convenient when you don’t need to convert the document to another format to edit it. With the PDFLiner, you just need to upload the file, and you can start working with it.

PDF Annotations Functions

Among the most typical annotation functions are comments, mark-ups, corrections, and signatures. They are quite similar in purpose. But, they are still diverse instruments for annotation, and people usually apply them in quite different situations.

Comments are used if you want to leave a small suggestion for the article`s author. So, in most cases, this function is popular among the editors. If you’re a reader, you will most probably use the mark-ups. They highlight or underline the text without changing its sense.

If you want to show the writer how you would have changed a particular sentence, you should apply the corrections. They change the meaning of the text. However, if you send it to the author, they may accept it or return it to the previous version. Signatures are used only in case you need to sign something.
