Save your document with notes.
Place a note on the exact PDF page where a reviewer needs context, a question, or a follow-up. Notes keep longer feedback separate from the page content while still anchoring it to a visible location.
Use notes for contract review, proofreading, study material, and team handoff. The original wording stays unchanged, and you can edit or remove the note before downloading the annotated PDF.
Yes. OnePDFs is free to use, requires no account, and does not add an extra OnePDFs branding watermark; watermark tools add only the watermark you choose.
Your files stay on your device and are processed locally in your browser; no upload to our PDF processing service is required. A browser copy can remain in this site's IndexedDB until you clear site data or the browser evicts it.
No. A note is stored as a separate PDF text annotation anchored to a page position, so the original wording remains unchanged.
The note content is exported with the PDF, but icon and popup behavior can differ between viewers. Reopen the downloaded PDF in your target viewer before sharing.
