About PDF Tool

Merge PDFs

Combine multiple PDF files into a single document. Drag to reorder files before merging — the output preserves original page order.

Split PDF

Extract specific pages using comma-separated ranges. Supports individual pages (5), ranges (1-3), and mixed input (1-3, 5, 8-10).

All PDF processing happens locally in your browser using pdf-lib. No files are uploaded to any server.

Technical Specification

PDF Manipulation Suite & Document Management Engine

Overview

The ToolsForges PDF Tool provides a comprehensive suite of PDF manipulation capabilities including merge, split, extract pages, and reorder — all executed entirely within the browser. Upload multiple PDF files to merge them into a single document, split a PDF into separate files by page range, extract specific pages for standalone use, or reorder pages within a document. The tool preserves all document content, annotations, bookmarks, and formatting throughout the manipulation process. All processing executes client-side, ensuring that sensitive documents, confidential reports, and private files never leave your device.

Feature Specifications

  • Multi-Document MergeCombine multiple PDF files into a single document with configurable page ordering, maintaining all original content, bookmarks, and annotations from each source file.
  • Page Range SplittingSplit a PDF into separate files by specifying page ranges, extracting specific sections for distribution, archival, or independent document management.
  • Page ReorderingDrag and reorder pages within a PDF document to reorganize content flow, correct page sequences, or create customized document versions from existing source material.
  • Page ExtractionExtract individual pages or page groups as standalone PDF files, creating separate documents from specific sections of a larger source document.

Architecture

The PDF tool uses PDF.js for document parsing and a custom PDF manipulation library for page extraction, reordering, and merging operations. The UI provides drag-and-drop page reordering with a visual thumbnail preview grid.

Frequently Asked Questions

What is the maximum number of PDFs I can merge?

The tool handles practical merge operations with up to several dozen source files. Very large merge operations with hundreds of files may experience processing delays depending on total document size.

Will bookmarks and annotations be preserved?

Bookmarks and annotations from source documents are preserved during merge operations. Page reordering adjusts bookmark destinations to reflect the new page sequence.

Can I merge password-protected PDFs?

The current implementation processes unprotected PDF files. Password-protected documents must be decrypted before merge or manipulation operations.

Is my PDF data stored?

No. All uploaded PDF files and manipulated output are processed entirely within your browser. No document content is transmitted to external servers.
