Overview & Background
The Portable Document Format (PDF), formalized under ISO 32000 specifications, serves as the worldwide foundation for legal filings, academic papers, regulatory submissions, and technical manuals. While generating documents across diverse word processors and scanner hardware, page numbering is frequently omitted, corrupted, or fragmented across multi-part merges. In civil litigation, regulatory discovery, and transactional contracts, unnumbered or inconsistently sequenced documents can result in procedural rejection, chain-of-custody disputes, or confusion during courtroom proceedings. Adding sequential page numbers, Bates identifier prefixes, or formal header/footer stamps transforms loose scans into organized, court-admissible records. Traditional online document editors force professionals to upload confidential contracts, internal audits, and sensitive personal disclosures to remote cloud environments. Transmitting legal and proprietary files across third-party networks introduces severe confidentiality liabilities, unauthorized server logging risks, and potential breaches of attorney-client privilege or data protection laws. Kitiverse eliminates these security hazards through an air-gapped, zero-upload architecture. All PDF parsing, font embedding, dynamic coordinate calculations, and vector text stamping are executed 100% locally inside your web browser memory buffers using typed arrays and WebAssembly. The document pagination engine calculates exact typography bounding boxes using standard PDF Type 1 vector fonts (Helvetica, Times Roman, and Courier) to prevent clipping against document print margins. Users can select from 6 standardized alignment points (top or bottom across left, center, and right margins), customize starting sequence numbers, skip decorative cover pages, or format sequential Bates stamps (such as 'DOC-00001') with microscopic precision.
