FAQs

Can I directly highlight an image in PDF?

No, you can’t highlight images directly. In PDFgear and Adobe Acrobat, you can use the Drawing or shapes tools to draw attention to parts of the image by adding shapes like circles, rectangles, or freehand lines.

You can change the color and opacity of the shapes to resemble a highlight effect.

Is there a way to highlight unselectable text within an image?

If the text is part of an image (i.e., not selectable text), you won’t be able to highlight it like normal text.

However, with the Area Highlight feature in PDFgear software, you can highlight the text in PDF using a rectangle highlight.

How do I remove highlights or annotations from an image in a PDF?

In PDFgear, click on the Comments button on the leftmost panel and you’ll see a list of all PDF annotations including highlights. Select the unwanted ones and click Delete to remove them.
