- Export. The marks become part of the page.
Frequently asked questions
Can I change the color?
Yes. Every mark can be recolored, moved and resized until you export.
Does the tool highlight the text automatically?
No. You drag the mark over the passage, like a highlighter pen on paper. That is why it also works on scanned pages with no recognizable text.
Is my file uploaded?
No. The PDF is opened, marked up and exported in your browser and never leaves your device.
Will the recipient see the highlights?
Yes, the same in every PDF program, because on export they become part of the page. That also means they cannot be hidden afterwards; keep the original.
Can I add comments too?
Yes. With “Text” you put a note next to the passage, plus arrows, rectangles, checkmarks or freehand strokes.
What does it cost?
Nothing. Tools that run in your browser are always free and need no account.

How the handover works →Make the important parts stand out
When you review a contract, correct minutes or send an invoice back with questions, you want to point at particular passages. With “Highlight” you lay a colored marker over the passage, underline it or strike it out, and write a short note beside it. The recipient sees at once what it is about.
Like a highlighter pen
The mark is dragged over the passage, not tied to the text. That has an advantage: it works on any page, including scanned documents and photos where a program recognizes no text. Every mark can then be moved, resized or deleted, and undo works until you export.
Highlighting is not redaction
A highlight draws attention; it hides nothing. The “Cover up” tool also only places a box over the spot; the text below stays in the file. If details really must not be passed on, remove them from the file with “Redact PDF”.
