Add Sticky Notes to a PDF, Free — Right in Your Browser
Click anywhere to drop a real, clickable comment — a genuine PDF sticky note, the kind any standard PDF viewer recognizes, not just a drawing on top of the page. Nothing you upload here is ever sent to a server.

A real comment, not just a picture of one
Most browser-based "annotation" tools just draw a flat image onto the page — it looks right until you open the file somewhere else, and there's nothing left to click. This one builds an actual PDF comment annotation into the file itself, the same object type every standard PDF viewer already knows how to show. Open your downloaded file in any standard PDF reader, and the note is still there: a small icon you can click or hover to read, exactly like the comments built into that app.

Frequently asked questions
Are these real sticky note comments, or just a picture drawn on the page?
They're real — each one is a genuine PDF comment annotation, not just a flattened image. Open your downloaded file in any standard PDF viewer and the note is still there, clickable and editable, exactly like a comment made in that app.
Can I change the color or move a note after placing it?
Yes — select a note to drag it to a new spot, pick a different color, or delete it entirely.
Is my PDF uploaded anywhere to add notes to it?
No. Everything happens in your browser using JavaScript. The file never leaves your device.
Is there a file size or page limit?
No. Since nothing is uploaded to a server, there's no server-side limit — the only ceiling is what your own device's memory can handle.
