Merge PDF — Combine Multiple PDF Files into One Document
The Merge PDF tool combines multiple PDF files into a single document with drag-and-drop reordering. Upload your PDFs, arrange them in your preferred order, and download one merged file. Free users can merge up to 3 PDFs; Pro users can merge unlimited files up to 20 MB each.
The tool uses pdf-lib to read each uploaded PDF, extract all pages while preserving formatting, embedded fonts, images, and links, then assembles them into a new combined document. Drag-and-drop reordering lets you arrange the files in exactly the order you want before merging. The entire process runs in your browser — no uploads to external servers.
Office workers merge scanned documents, reports, and forms into single files for email or archiving. Students combine assignment pages, notes, and references into unified submission files. Legal professionals assemble multi-section contracts and supporting documents into complete packages.
Merge PDF is part of the facilita.tools suite of free browser-based document utilities. Available in Portuguese, English, and Spanish, optimized for desktop and mobile browsers.
