PDF SealBox is a browser-based toolkit for adding visible text or image stamps, seam seals across page edges, page numbers and watermarks to PDFs. It can also split PDFs, convert images to PDF, and export pages as JPG or PNG. Files are processed locally in your browser, and no account is needed. A visible stamp is not a certificate-based digital signature.
