Frequently asked
Will my comments show in Acrobat?+
Yes. Notes are saved as standard PDF comment annotations, and everything else is drawn into the page, so every reader shows it.
Can I do more than this on the same page?+
Yes. This opens the full editor: text, images, drawing, shapes, highlights, whiteout, links, notes, signatures and page tools are all in the toolbar.
Is my file uploaded?+
No. The editor runs inside your browser, so the document never leaves your device. Edits are kept as a draft on your own device until you start over.
