Interactive PDF Page Numberer & Pagination Stamper Workspace
Add customizable page numbers, header/footer pagination, and Page X of Y stamps to PDF documents directly inside your web browser. This client-side utility uses in-memory client-side JavaScript to stamp vector typography onto pages without uploading your files to third-party cloud servers.
How This Tool Works (100% Client-Side Engine)
The tool reads the PDF binary into an ArrayBuffer and parses the page tree using pdf-lib. Based on your chosen positioning grid and margin offsets, the engine calculates exact point coordinates and draws vector text overlays onto each target page object using standard Type 1 fonts before emitting a clean Blob download URL.
Step-by-Step Guide
Upload PDF Document
Drag and drop your PDF into the upload dropzone or select it from your device file manager.
Customize Position & Number Format
Select your preferred layout position (e.g. Bottom Right), numbering scheme (e.g. Page 1 of 12), and font styling.
Configure Page Offset & Stamp
Specify which page to start numbering on (skipping title sheets) and click Stamp & Download to export your numbered document.
Why Use This Tool: Privacy & Performance
Preparing formal reports, court submissions, corporate proposals, and academic manuscripts requires precise page numbering. However, uploading confidential agreements, financial disclosures, or medical charts to free online PDF converters introduces severe data privacy hazards and regulatory violations under GDPR and HIPAA. Traditional web tools store files on remote storage buckets and process them on third-party backend servers. ToolByte eliminates this privacy vulnerability through a 100% in-browser pagination engine built on pdf-lib. When you drop a document into the staging workspace, your computer loads the raw PDF byte array into local physical RAM. You can visually select 6-point grid positions (header or footer, left, center, right), choose pagination schemes like Page 1 of 12 or Roman numerals, adjust font size and color, and skip cover pages. Stamping takes fractions of a second and occurs purely in browser memory with zero network telemetry.
