Highlight PDF text in five reading colors — mark passages in seconds.

Highlight text in PDFs using five reading colors. Mark important passages, add notes and export a clean annotated PDF. Free, browser-based, no sign-up.

Mark key passages in five colors to distinguish priorities or categories.

Highlight directly on any PDF — scanned or text-based — without conversion.

Download the marked-up PDF ready to share with colleagues or students.

Is Highlight free to use?

Yes. Highlight is free for personal use, does not require an account and does not add a watermark to your exported PDF.

Are my files safe in Highlight?

Core PDF actions run in the browser whenever possible. When a conversion needs a worker, files are processed through encrypted temporary storage and cleaned automatically.

Can I use Highlight on mobile?

Yes. The tool works in modern mobile and desktop browsers, so you can upload, adjust and download PDFs without installing a desktop app.
