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.

How Pdf Tool Works in Your Browser

The PDF Merge & Split Tool on ToolsForges combines multiple PDF files into a single document or extracts specific pages from an existing PDF into separate files, all executed entirely within your browser sandbox. Upload your PDFs using the file picker or drag-and-drop interface, drag to reorder pages visually, select individual pages or page ranges for extraction, and download the result instantly. The engine uses the browser's File API and a client-side PDF parsing library to read and manipulate PDF document structure without transmitting any bytes to a remote server. Page thumbnails render in real time for visual page selection, confirming content and orientation before merging or splitting. The output preserves all original formatting, bookmarks, annotations, form fields, and embedded metadata from every source file. This tool is essential for professionals who need to combine contract sections, extract specific pages from reports, reorganize document sequences, or create custom PDF compilations while maintaining strict data confidentiality for sensitive legal, financial, or medical records.

Key Features

  • Combine two or more PDF files into a single document with drag-to-reorder page management. The merge engine preserves all original formatting, bookmarks, and annotations from every source file.
  • Extract specific page ranges from a PDF into separate files. Select individual pages, continuous ranges, or custom selections for precise document splitting.
  • Page thumbnails render in real time for visual confirmation before merging or splitting. Verify page content and orientation without opening each page in a separate viewer.
  • All PDF parsing and manipulation occurs entirely in the browser. No documents are uploaded to any server, ensuring complete confidentiality for sensitive legal, financial, or medical records.

Frequently Asked Questions

What is the maximum file size supported?
The tool handles PDFs up to several hundred megabytes depending on your browser's available memory. Very large files with thousands of pages may experience brief processing delays during parsing and thumbnail rendering.
Does merging preserve bookmarks and annotations?
The merge engine preserves internal PDF structures including bookmarks, annotations, form fields, and embedded links. Cross-document bookmark conflicts are resolved by appending source file identifiers.
Can I rearrange pages before merging?
Yes. Drag-and-drop page thumbnails to rearrange the merge order. You can also remove unwanted pages from the merge queue by clicking the remove button on each thumbnail.
Are my PDF files uploaded to any server?
No. All file processing occurs entirely within your browser using client-side JavaScript and the File API. Your documents never leave your device and are not transmitted to any external server.

All data processing for Pdf Tool runs 100% locally in your browser using client-side JavaScript. No data is 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.
