How to Markup a PDF: The Ultimate Guide 2023


How to markup a PDF file without distorting the format or going through the slow and frustrating process of converting the file to a Word document is a growing concern for brands that frequently collaborate on the go. 

Team collaboration improves dramatically when everyone can work on PDF files without delays. Therefore, we have prepared this detailed guide to help you in marking up a PDF file, improving productivity, and collaborating more effectively.

Before we jump right into it, however, let’s describe what makes the editing of PDFs possible.

Most Important Features You Need to Markup a PDF Document 

Features You Need to Markup a PDF Document

Making PDF markup and annotations possible is one thing; seamlessly and actively collaborating with teammates is another. Some important features can make both collaboration and annotation possible in a PDF, including:


This feature helps you draw attention to specific areas in a PDF document. The best PDF markup tools offer a variety of highlight colors, allowing you to place different degrees of emphasis on PDF content. 

Typically, two types of highlighters exist. Text Highlighters allow you to highlight text in a simple, straightforward order as you cover them with your cursor. Freehand Highlighters function more  like traditional highlighting pens that allow you to draw translucent colors within shapes, charts, or regions on your PDF document. 


In case the highlighter does not meet your needs, the drawing tool is a feature to consider. It allows you to draw both regular and free-hand shapes, arrows, and more on a PDF document. This can be especially important if you’re working on a manuscript.


The best PDF markup tools are cloud-based and have share buttons. This allows you to add your teammates to the file using their emails and collaborate in real-time. Compared with cloud-based sharing, working on documents through a series of email attachments can be at least three steps slower. 


Communication makes collaboration effective. After sharing and highlighting/drawing on a PDF document, the comment feature allows you to add comments and suggestions for other collaborators to see. This will ensure that work is organized. 


This feature allows you to keep private sticky notes on documents – notes that only you can read. This can be especially useful to keep you organized when you’re working on several documents.

Underline & strikethrough

These features are essential when reviewing documents. Underlining sentences (or words), like highlighting, is a way to draw attention to them and is often followed by a comment. Strikethroughs, on the other hand, may be used during a document review to identify unwanted text.

5 Reasons Why You Should Use a Professional PDF Markup Tool

5 Reasons Why You Should Use a Professional PDF Markup Tool

Using a PDF markup tool goes beyond making your brand look modern. There are real personal and organizational benefits to using a professional PDF markup tool. 

Speed up the review and approval process 

Coherent content is essential for good brand management. And teammates need to review documents and designs for corrections and comments before the content eventually goes live. 

Normally, the document review and approval process can take weeks with emails flying back and forth. Using a professional PDF markup tool eliminates needless email chains and allows real-time collaboration that speeds up review and approval.

Collaborate easily 

At times, it takes the effort of an entire team of creative professionals (designers, writers, editors, project managers, etc.) to produce a perfect document. Having the same PDF document attached repeatedly on emails to every creative on the team can be a nightmare. 

With a professional PDF annotation and markup tool, every team member can work on the file in real-time, leaving comments and suggestions as they progress. Teams bond better and work gets done faster when all hands are on deck.

Increase productivity

Businesses grow when more work can be done in less time. As teams collaborate, documents are reviewed and approved faster, facilitating work completion in less time. 

Keep track of (and revert) changes

In a more traditional scenario where PDFs are attached to emails, it becomes difficult to keep track of document versions after emails have bounced back and forth a few times. 

Using a professional PDF markup tool with document approval software, you can keep track of changes made on PDF documents, jump back to previous versions of the same document, and easily know when a document is completed and approved.

Give specific feedback

With several collaborators on a single document, it might seem difficult to direct feedback to a specific individual. However, with a professional PDF markup tool, you can mention people in comments, making feedback more direct.

How to Set Up a Document Review Process with an Online PDF Markup Tool

In addition to knowing how to Markup a PDF, setting up a document review process is essential for teams that want to see their projects completed quickly and easily. 

Project managers are particular about getting the document review and approval process right, and this is how to set up the process with ease. 

1. Upload and share the document. 

This is usually done after the management team has approved the project, and teammates have completed the duties assigned to them. 

Simply upload the document on Filestage using the drag-and-drop feature. Then, invite reviewers to submit feedback by adding their email addresses or sharing the link. 

2. Collect and discuss feedback on your document. 

With the shared links, reviewers can open and view the document to leave feedback and comments on the PDF file. They can also edit or annotate specific areas of the document to make their feedback easier to understand. 

The project manager needs to ensure that every comment and piece of feedback is clear. If not, discuss the feedback directly with the reviewers for clarity.

3. Edit the document. 

After all reviewers have left their feedback, editors can go further to effect changes on the document according to the reviewers’ comments. Since PDF documents often cannot be edited directly in the annotation software, editors can use other tools (e.g. Google Docs or MS Word) to make revisions on the document. 

4. Get final approval. 

After changes have been made, the final document is re-uploaded to Filestage and shared with the reviewers once more. They can now view the revised PDF and confirm that all feedback has been implemented correctly, leaving nothing unnoticed. 

If the document satisfies all criteria set by the team and reviewers, the final approval is given, and the project is completed.
