Everything you need to review
Three ways to leave a mark
Reviewing a document usually means three moves: flag the lines that matter, sketch something the words can't say, and write down what you're thinking. BrowsePDF gives you all three on top of the page, so your feedback lands right where the reader is looking instead of in a separate email.
- Highlight sentences and whole paragraphs
- Draw freehand ink to circle or connect
- Add text notes anywhere on the page
- Pick colors so different passes stand apart
Your comments stay yours
Picture marking up a colleague's draft contract with a blunt note in the margin. Because BrowsePDF works entirely in your browser, that PDF and every comment you add stay on your device — never uploaded, never parked on a server where the wrong person could read your candid feedback.
Review on the couch or at the desk
Annotation runs in the browser you already have, so you can highlight a report on your laptop or thumb through it on a tablet without installing an app or signing in. Same tools, same file, wherever you're reading.

Annotate PDF questions
Does my file get uploaded when I annotate it?
No. The PDF and every highlight, ink stroke, and note stay in your browser on your device. Nothing is sent to a server.
Is annotating free, and is there a watermark?
Yes, it's completely free with no login, and your downloaded markup carries no BrowsePDF watermark.
What's the difference between annotating and editing?
Annotating adds highlights, ink, and notes on top of the page. Editing changes the document's actual text. Reach for annotation when you're reviewing, not rewriting.
Can I highlight text on a scanned document?
You can draw freehand ink and add notes over any scan. Text highlighting works best where the PDF has real, selectable text underneath.
Will the person I send it to see my markup?
Yes. Your highlights, ink, and notes are baked into the PDF you download, so they show up in any standard PDF viewer.
About annotating PDFs
Most PDFs that cross your desk aren't yours to rewrite — a contract to review, a design proof, a report a teammate wants a second opinion on. What you actually need is a way to say "this line," "not this," and "what about here?" without retyping the document. Highlighting, freehand ink, and margin notes do that: they put your reaction next to the exact thing you're reacting to.
Feedback is often candid, which is why it shouldn't ride through a stranger's server on its way back to the author. BrowsePDF keeps the whole review in your browser, so the document and your comments never leave your device. When you're done, the marked-up file downloads as a normal PDF that opens anywhere — and it's still sitting in the editor if you want to sign it, add a page, or tidy it up before sending.
