27/12/2023 website

PDFs, or Portable Document Formats, are used for secure online document sharing. They're commonly used for electronic signatures and have been around for a long time. PDFs can contain text, as well as audio and video.

If you often work with PDFs and need to add comments or signatures, you might want to write on them with notes. We'll show you how to write on PDFs on both Windows and Mac OS using PDF annotator apps that support pen input.

What are PDF annotations?

PDF annotations encompass digital notes, highlights, drawings, or comments integrated into a PDF document to augment its content or provide commentary.

When you engage in text markup, you are essentially engaging in a dialogue with the material you are perusing. Thus, annotations hold significant importance.

Within a PDF annotator, you'll encounter a diverse array of markup tools at your disposal. These tools assist you in marking and commenting on your reading material. You can underline, highlight, add comments with arrows, use symbols, enclose text in shapes, add virtual Post-It notes, and more.

Leverage the selection and markup tools to enrich your PDF annotations. You can use a digital pen to write, draw, make shapes, add notes, sign, and change the format of your annotations.
