About the Merge / Split PDF
Performs direct byte-level manipulation of PDF document page dictionaries. Append multiple documents into a consolidated file, reorder pages, or extract specific page intervals without degrading vector sharpness or recompressing embedded graphics.
How to Use the Interface
Select Mode & Upload
Choose Merge to combine multiple files or Split to extract pages from a single document.
Arrange or Specify Pages
In Merge mode, reorder documents with up/down controls. In Split mode, enter comma-separated pages or ranges (e.g. 1, 3, 5-8).

Technical Format Specifications
- PDF (.pdf) documents (single or multiple)
- Combined or Extracted Vector PDF (.pdf)
- •Password-encrypted PDFs cannot be merged or split without entering the owner password.
- •Combining extremely large batches (e.g. hundreds of high-resolution graphic pages) on mobile devices may exhaust browser RAM.
- Direct byte-level dictionary copying preserves vector paths and font fidelity without re-rasterizing.
- Note: Existing internal metadata (such as author and creation date) within the original PDF streams is retained in the output.
Common Practical Use Cases
Combining Multi-Part Invoices
Merge separate scanned receipts, cover letters, and statements into a single cohesive document.
Extracting Relevant Excerpts
Isolate specific chapters or signature pages from lengthy reports for targeted sharing.
Frequently Asked Questions
How do I extract non-consecutive pages?
In Split mode, enter comma-separated numbers and ranges like "1, 3, 5-8". The engine parses and extracts exactly those pages.
Does merging reduce document sharpness or image quality?
No. The tool copies native vector page streams directly without rasterization, preserving full original clarity.
