- The page says files up to 50 MB are processed locally, with zero bytes uploaded; that privacy claim is not independently verified.
Field notes
The visible workflow starts with a local file picker or drag-and-drop area, alongside an option to load a sample invoice. Presets cover several document states, from payment and receipt markings to approval, cancellation, and confidentiality; the page also describes custom rectangular stamps and circular seals. The site states a 50 MB limit and says files remain in the browser, but that privacy behavior is not independently established by the extracted page.
