1. Zero File Upload Guarantee
OnlinePDFRedact.com operates as a purely client-side web application. When you drag and drop or browse for a PDF document, the file is read directly by your web browser using the standard HTML5 File API and WebAssembly runtime.
Unlike traditional online PDF editors, no file bytes, document previews, or extracted text are ever transmitted to our web servers or any third-party cloud infrastructure. You can verify this independently at any time by opening your browser's Developer Tools (Network tab) while loading and redacting a document.
