Options for Highlight PDF

Leave empty for every page. Use ranges like 2-5 and lists like 1,4,9.

The highlight is a translucent band placed by coordinates rather than attached to recognised words. Placement is measured in percentages from the top-left corner of the page, so it works on any page size.

About this tool

Highlighting is how people mark what matters in a document they are about to hand over: the deadline, the amount, the clause under discussion. A translucent band leaves the text fully readable while making the important part impossible to miss.

Set the page, the band's position and size as percentages, and pick a colour and opacity. Around 40% opacity behaves like a physical highlighter pen. Because placement is coordinate-based, you can highlight anything on the page — text, a figure in a table, or part of an image.

What it's good for

  • Marking the key clause in a contract before a meeting.
  • Pointing out a total or deadline in an invoice.
  • Flagging a row in a table for a colleague.
  • Preparing a document for study or review.

Questions people ask

Can it find and highlight a phrase automatically?
Not yet — you position the highlight yourself, which also works on scans and images.
What opacity should I use?
Around 40%. Higher values start to obscure the text.
Can I remove it later?
No, it becomes part of the page. Keep your original.
