How to highlight text in a PDF

A figure in a report highlighted in yellow.

The pointer drags across “conversion rate rose to 4.2%” and it turns yellow
  1. Pick Mark up

    Press Mark up on the left. Above the page choose what to do — Highlight, Underline, Strike out, Note, Draw, Rectangle, Ellipse — and the colour.

    The markup tools and colours above the page
  2. Drag across the words

    The words are picked line by line as you drag, like selecting text in a document. Let go, and they are marked.

How the markup is added

Markup goes on the page as standard PDF annotations: the same kind that Acrobat and the browsers' PDF viewers make and show.

A highlighted phrase
  1. Fitted to the words

    Highlights, underlines and strike-outs follow the lines of text you drag across, even across several lines.

  2. Shown everywhere

    Every PDF reader shows the markup; a reader that knows annotations can list, change or remove it.

  3. The page stays as it was

    The document's text is not touched: markup lies on top of it and can be taken off.

  4. Your style

    Five colours; for lines and shapes a thickness, and for underlines solid, dashed, dotted, wavy or double.

What you get

Highlight, underline, strike

Fitted to the words you pick.

Notes

Click where the note goes and write it.

Draw

Freehand with the mouse, a pen or a finger.

Rectangles and ellipses

To frame a figure or a part of a drawing.

Move, resize, delete

Click a markup to change it.

Standard PDF markup

Shown in Acrobat, Chrome, Edge, Preview.

Good to know

Text in a scan

A scan has no text to pick: use a rectangle or a drawing to mark it.

Remove a markup

Click it and press Delete, or the Delete button by it.

Changing the words

To change the text itself rather than mark it, use Edit text.

Questions

Will my highlights show in Adobe Reader?

Yes. They are standard PDF annotations, shown by Adobe Reader and every other PDF reader.

Can I highlight in other colours?

Yes: yellow, green, blue, red or black, picked above the page.

Can I add a comment to a PDF?

Yes: choose Note, click where it goes and type. Readers show it as a note icon with your text.
