Fresh PDFPages are rebuilt into a new PDF before protection.
Important: This browser version rebuilds pages as images and then applies a password/encryption layer supported by the PDF library. Interactive forms, links, annotations, selectable text and some metadata may not be preserved. Keep your password safe; PixelToolkit cannot recover it.
