Client-side vector typography stamping for reports, legal filings, and theses
When combining multiple contracts, research chapters, or financial disclosures into a consolidated PDF, individual sections often have mismatched or missing page numbers. Adding unified pagination is essential for legal compliance, academic submissions, and corporate presentations.
Modifyle's client-side PDF stamping engine inserts clean vector text directly into your document's content streams without converting pages to heavy images. You have complete control over position (Top/Bottom, Left/Center/Right), font family, font size, margins, and custom numbering offsets.
Because processing executes 100% inside your browser, sensitive legal briefs, patient records, and tax returns remain completely confidential and secure.
