How do I highlight text in a PDF?expand_more
Upload your PDF, select the text you want to highlight, pick a color, and apply. The highlight is added as an annotation.
What colors are available for highlighting?expand_more
Yellow, green, blue, pink, orange, and more. Choose any color that suits your needs.
Can I remove highlights later?expand_more
Highlights are added as annotations, so they can be removed by compatible PDF editors. To make them permanent, use Flatten Annotations.
Does this work on scanned PDFs?expand_more
Only if the PDF has a selectable text layer. For scanned documents, run OCR first to make the text selectable.
