Quick Answer: What is the PDF Toolbox?

[!NOTE] The PDF Toolbox is a collection of high-performance nodes that perform standard PDF operations like merging multiple files, splitting single documents into pages, compressing sizes for email, and correcting page orientation. These nodes form the foundation of most document automation workflows.

Core Capabilities

1. Advanced PDF Merging

Combine hundreds of individual files into a single, cohesive document. The node automatically handles inconsistent page sizes and merges encrypted documents (provided the Unlock Node is used upstream).

2. Intelligent Splitting & Bursting

Range Mode: Extract specific pages (e.g., "1, 5, 10-20").
Burst Mode: Automatically split every page into its own individual PDF file, perfect for downstream AI Extraction per page.

3. Professional Compression

Three levels of compression (Extreme, Recommended, High Quality) that use advanced image re-sampling algorithms to reduce file sizes by up to 90% without losing text readability.

Configuration Guide

Operation	Setting	Use Case
Merge	Sequence	Order files alphabetically or by timestamp.
Split	Range String	Use notation like `1-5, 8` for targeted extraction.
Compress	Quality Level	Use `Extreme` for mobile-first attachments.
Rotate	Degree	`90`, `180`, or `270` degree clockwise rotation.

Best Practices

Large Batches: When merging very large files (500MB+), split the batch into smaller groups to improve reliability.
Preprocessing: Always Flatten a PDF before archiving it to ensure form fields and signatures are non-editable.

[!TIP] Building a legal archival system? Use the Metadata Node to automatically inject Title, Author, and Subject tags into your resulting PDFs.
