How to Highlight PDF Text Online — Free Color Highlighter

Highlighting key passages in a PDF helps you study, review, and collaborate more efficiently. PDF me offers a free in-browser highlighter with five reading colors so you can color-code sections without installing any software or creating an account.

What is the PDF Highlight tool?

The Highlight tool in PDF me lets you select any text in a PDF and apply a colored highlight — yellow, green, blue, pink, or orange. Highlights are embedded in the file itself, so they remain visible when the PDF is opened in any reader. You can apply multiple colors to categorise and prioritise information at a glance.
