What is included
Text notes, drawings, shapes, area highlights, visual whiteout, images, visual signatures, Undo and PDF download are available in the browser editor. The current file-size guard is 200 MB; very large files still depend on device memory.
What is not included
The editor does not securely redact content, provide certified digital signatures or convert PDFs to formats other than Word: these features are not offered at all, free or paid.
No account or subscription
The present version has no login, subscription checkout or payment processing. A linked PDF source may ask you to grant the Chrome extension access to that site, but that is a browser permission, not a charge.
