How to Highlight Text and Key Points in PDF Online
Studying textbooks, preparing legal briefs, and reviewing reports requires highlighting essential passages. WebTorq provides a responsive highlighter tool with customizable translucent colors that works on digital and scanned PDFs alike.
Apply yellow, green, pink, or blue highlights with tuned opacity so that underlying text remains easily readable.
Overlay highlights are drawn over the canvas layout, making them compatible with both selectable text files and flat scanned pages.
For broader review capabilities including text boxes and arrows, use Annotate PDF.
This tool operates in a sandbox directly inside your web browser. All parsing, processing, and downloads are rendered locally. Your file size, metadata, and contents never cross the network. It works completely offline.
Frequently Asked Questions
How does highlighting work in this tool?
WebTorq applies a semi-transparent colored overlay box across selected document coordinates, allowing underlying text and diagrams to remain visible.
Can I choose different highlight colors?
Yes. You can select from standard highlighter colors including Yellow, Green, Blue, Pink, and Orange to color-code your notes.
Can I remove or reposition a highlight?
Yes. Click on any highlight box to select it, then drag to adjust its position or press Delete to remove it.
Does highlighting work on scanned documents?
Yes. Because WebTorq uses coordinate overlay highlights, it works on both digital documents and scanned image pages.
Is my document uploaded to external servers?
No. The highlighting workspace executes locally in your browser memory; the document is not sent to WebTorq.
