Make text bold in a PDF on Firefox

Works in the browser on Firefox — nothing to install. Large buttons make it easy to use on touch screens.

Steps

  1. Open the PDF.
  2. Add a text box.
  3. Choose the bold weight.
  4. Save.

Tip: Use the document's own bold face where available.

Keep the original font, weight and spacing when editing a PDF, and understand embedded and subset fonts.
