I usually send full sketch sets and wait for comments, but that invites scope creep and indecision. Recommend the best…
Open your PDF file in Adobe Acrobat.
Click the Comment button in the toolbar to display the commenting tools.
Select the annotation tool you want to use, such as Note, Highlight, Text Box, or Draw.
Click on the PDF page where you want to add your comment or annotation.
Type your comment or draw your annotation as needed.
Click away from the annotation or press Escape to save your comment or annotation.
You can use multiple annotation types in one session, such as highlighting text and adding sticky notes for detailed feedback.
This runs in the Acrobat app - there is no separate API for this task.
Comments are typically text-based notes, like sticky notes or text boxes, used to add specific feedback or questions. Annotations are more visual, including highlights, underlines, strikethroughs, and drawing markups. Both serve to add a layer of review notes to a document without changing the original content. They help you communicate clearly about specific parts of a PDF.
Sanitizing a PDF is crucial because comments and annotations are stored on a separate layer. If you share a file without sanitizing it, these review notes, even deleted ones, can still be recovered. This could lead to sensitive information or internal discussions being leaked. Using 'Protect > Sanitize' removes all hidden data, ensuring your 'final' document is truly clean and free of any unwanted comments or metadata before it leaves your hands.
You can use the drawing markup tools to draw a box or an arrow pointing to the signature line. Then, add a sticky note or text box next to it saying, 'Please sign here.' This clearly shows your client exactly where to act, setting a clear expectation for them without changing the contract itself.
