About Merge PDF Tool

Merge PDF is a professional, browser-based tool for combining multiple PDF documents into a single file. The application runs entirely client-side using PDF.js and pdf-lib libraries, ensuring complete data privacy as no files are uploaded to external servers.

This tool is designed for users who need to consolidate multiple PDF documents while maintaining full control over file sequencing, page orientation, and document organization without compromising security or requiring software installation.

Technical Capabilities

  • Client-Side Processing: All PDF operations execute locally in your browser using WebAssembly and JavaScript libraries, with no server communication.
  • Unlimited File Capacity: No restrictions on the number of PDFs or total file size, limited only by available system memory.
  • Interactive Reordering: Drag-and-drop interface powered by Sortable.js for intuitive document sequencing before merge operation.
  • Page Rotation: Individual page rotation controls (90 degree increments) with real-time preview updates.
  • Complete Privacy: Zero network requests during processing; files cleared from memory immediately after download.
