# Merge PDF

Canonical page: <https://codeasystem.com/tools/pdf/merge-pdf/>

Merge two or more ordinary, unlocked PDF files into one document. Add the files, arrange their order, and download the combined PDF.

## How it works

The tool copies the pages from each selected PDF into a new PDF in the displayed order. Processing happens in the browser tab, so files are not uploaded to CodeASystem.

## Limits

This tool is intended for valid, unlocked PDFs. Encrypted, damaged, or unsupported files may not work. Check the downloaded file before sharing or relying on it.

It does not offer OCR, PDF conversion, compression, password removal, signing, redaction, or professional document advice.
