Highlighting works best when the workspace is optimized for review rather than full editing. Pdf Clarity's annotate route exists for exactly that reason: it puts markup tools first and keeps export, share, and flatten actions in the same flow.

Why the annotate route is faster than the full editor

When the goal is highlight, underline, comments, shapes, or stamps, the annotate route removes the noise of a broader editing interface.

That matters on review jobs because you can start marking up immediately and still keep save, export, and flatten in the same workflow.

How to highlight a PDF in Pdf Clarity

Upload the file on Annotate PDF and let the review-first workspace open with the document ready.

Use highlight and related review tools, then export, flatten, or continue to another route if the next step is signatures, compression, or page cleanup.

  • Choose Annotate PDF for markup-first work.
  • Keep related comments and shapes in the same review session.
  • Use the canonical export path when you finish instead of a separate review-only download.

Common next step after highlighting

People often compress, sign, or protect the file after review. The useful move is to keep the file in the same browser workflow and jump straight to the next route instead of starting over.
