How to highlight text on any webpage

Updated September 24, 2026

Quick answer

Click the Highlite icon, pick Highlight (or press H), then select the text with your mouse. The selection gets a background in the active color, one of five. Highlite saves it in your browser and shows it again when you open Highlite on that page.

Steps

  1. Open the page and click the Highlite icon to show the toolbar.
  2. Click Highlight in the toolbar, or press H.
  3. Pick a color in the panel that appears. The highlighter uses color only: the S to XL sizes do not apply to it.
  4. Select the text you want to mark. A selection can run across several paragraphs; Highlite colors each piece of text it covers.
  5. To remove a highlight, hover it and click its delete button, or switch to Eraser (E) and click it. Undo (Ctrl+Z, or Cmd+Z on Mac) works too.

Use colors as a legend

The five colors are the same for every tool and every page. Give each one a meaning, for example one for key points, one for errors, one for questions, and the highlights stay readable in the screenshot you send later.

Adding a comment to a highlight

Highlights carry no text of their own. To explain one, place a sticky note or a text box next to it, or draw an arrow from the comment to the highlighted words.

Limitations

  • Highlite stores the highlighted words and their position in the page text. If the site changes that text, the highlight is not shown on your next visit.
  • Annotations are tied to the exact page URL. The same article opened with a different query string or #anchor counts as a different page.
  • Text inside images, PDFs opened in the browser viewer, canvas-based apps and browser pages cannot be highlighted.
  • Highlights are not searchable, and there is no list of every page you highlighted.

Frequently asked questions

Do my highlights stay after I close the browser?

Yes. They are saved in your browser as soon as you make them. After a restart Highlite starts switched off, so click its icon on the page and the highlights come back.

Can I highlight text in a PDF?

No. PDFs opened in the browser's built-in viewer cannot be highlighted with Highlite, and neither can text inside images or canvas-based apps.

Can other people see my highlights?

Not on their own screen. Highlights stay in your browser. To share them, capture a screenshot of the page, or export the annotations as a JSON file with Premium.
