PDF SealBox vs. The Zoomist

PDF SealBox is a set of six web tools for preparing everyday PDF documents. Add visible text or image stamps, place a split seal across pages, insert page numbers and watermarks, convert images to PDF or PDF pages to images, and split a PDF into smaller files. It is built for individuals and office teams who prepare forms, reports, and records for sharing or electronic archiving. Choose a tool, adjust its options, and download the resulting file. The stamps are visible marks on a document and are not cryptographic digital signatures.
