• Faster feedback cycles
• Better version control
• Contextual comments on exact design or content elements
• Enhanced project accuracy

For teams that regularly collaborate on visuals and documents, knowing how to annotate a PDF streamlines your workflow and cuts down on endless back-and-forth emails.

Click on a section of the document to leave a comment. Ideal for content suggestions, clarifications, and asking questions.

✍️ Highlight Text

Use the highlighter tool to draw attention to specific words, sentences, or paragraphs that need editing.

🖊️ Draw or Sketch

Freehand drawing helps visually explain layout changes or creative direction.

🟨 Use Shapes & Arrows

Box an area that needs revision or use arrows to guide the reviewer’s eyes to key elements.

Step 5: Export or Share the Annotated PDF

Once annotations are complete, you have two options:

• Export the file with annotations (PDF with markup)

This final step ensures your team or client gets a clear view of all suggestions and can implement them without confusion. Make sure to track changes and preserve previous versions for transparency.
