Another useful type of annotation is underlining that allows to draw a line beneath the text in order to stress some sections. Inserting comments is most valuable when you want to explain something or give more information.

The reasons for annotating PDFs are very diverse. For instance, annotations can help to facilitate communication between the team members as they share information and opinions.

They can also aid in arranging the information better by highlighting specific areas and writing comments. In addition, annotations enhance understanding since readers can write their comments and notes on the text.

For instance, if you decide to highlight some text, you mouse over to the highlighter tool icon. Train yourself with the tools you have and choose those that you will use for your annotations.

2.3 Add Annotations

With the annotation tool chosen, it is time to proceed with the insertion of annotations into the PDF document.

Highlight Text: When choosing the text you wish to highlight, place the cursor over the selected text and right-click. The highlight color will be applied to the selected text so that it is easily recognizable. In most applications, you get to select from a variety of colors to either categorize the information or prioritize it.

Add Comments: If you want to insert comments, move the cursor to the part of the text where you want to add the comment. A text box will appear that enables you to type in your note. You can use the comments to provide clarification, pose a question, or provide extra information concerning the text.

Draw Shapes: To draw shapes, use the shape tool in the toolbar. It can be round or rectangular, and even arrows are available in the shapes list. You select the shape and, holding down the left mouse button, draw the shape by moving the cursor on the document. Shapes are useful for pointing to certain areas or emphasizing a particular part of the layout.

Sticky Notes: To add notes, simply select a region of the browser where you want to add the note. A digital sticky note will appear, in the text box which is created, you can type in your message. Sticky notes are used when highlighting is insufficient and you like to place some reminder or additional comment right on the page.

2.4 Save The Annotated Pdf

After you are done with all the required annotations, it is important to note that all the changes made are saved.

To download the highlighted PDF, go to the ‘File’ tab or option on the toolbar. Next, click on ‘Save’ or ‘Save As. ‘ If you opted for ‘Save,’ then your annotations will replace the original file.

If you choose the ‘Save as’ option, then the current document is saved under a new name or in a different folder, retaining the previous one.

It is advisable to check that the file has been saved before closing the PDF annotation tool.

To make your PDF annotations more effective, here are some tips and tricks:

  • Make an outline and design using different colors for different types of annotations. For example, use yellow highlight, underlined blue text, and red for comments. It also eliminates the confusion of which type of annotation to look for in case one is needed as the colors make it easy to distinguish between the different types of annotation.
  • Try to be concise in your notes, as less writing on each line will help with accessibility. While taking notes, try not to write a lot of details. Just give brief information needed to make a specific decision.
  • Format each note in a certain way, and it is essential to be as consistent as possible with font, color, and other such options. This also helps ensure that the document has a neat and well-arranged appearance – well worth the time spent.
  • For quick reminders or additional comments, sticky notes are used since they are quite easy to connect to the relevant pages.
