How to Merge PDF
Join multiple PDF files into a single unified document cleanly — our local assembler combines layouts, pages, and metadata tables in your browser workspace.
Upload PDF Documents
Drag and drop two or more PDF files into the staging area, or click to load them from your drive.
Arrange Page Order
Drag visual card list elements to rearrange the document merging order, or expand files to select specific page ranges.
Combine File Data
The local parser reads individual page trees and appends vector coordinates into a singular PDF stream.
Download Unified PDF
Save your compiled PDF document instantly with fonts, outline guides, and table hierarchies fully preserved.
🔒 Standard Browser Security Sandbox
Your data assets remain strictly private. Document parsing functions utilize local machine memory engines exclusively — zero server transmissions, zero external logs.
Key PDF Merging Features
Drag-and-Drop Ordering
Organize file input arrays quickly using an interactive layout list container.
Partial Range Merges
Extract and join specific page subsets (like pages 1-3 from Document A and page 5 from Document B) cleanly.
File Outline Integration
Consolidate individual PDF bookmarks and table of contents trees into a single index list.
Form Fields Retention
Maintain interactive fill fields or flatten form inputs while stitching sheets together.
Sandboxed Assembler Technology
Combines documents in local virtual memory space. Files are never sent over external network routes, protecting financial data or personal identity sheets from cloud leaks.
