What Is the Merge PDF Tool?
The Merge PDF tool is a browser based utility that allows you to combine multiple PDF files into one organized document. You can upload several PDF files, arrange them in the correct order, remove unwanted files, choose a custom output name and download one merged PDF.
This tool is part of the PDF Mentor free PDF tool collection. It is useful when information is divided across several documents and you want to create one complete file for easier storage, sharing, printing or submission.
The complete process takes place inside your browser. Your PDF files are not uploaded to an external server during normal use, and no account or software installation is required.
Why Merge Multiple PDF Files?
Working with several separate PDF files can be inconvenient. A client, teacher, colleague or government portal may require one complete document instead of several individual attachments.
- Combine scanned pages into one document
- Join multiple report sections
- Organize invoices and receipts
- Combine application documents
- Create one file from several chapters
- Join contracts and supporting pages
- Prepare assignments for submission
- Organize monthly statements
- Combine project documents
- Reduce the number of email attachments
How to Use This Tool
Upload at least two PDF files using the file selection button or drag and drop area.
The tool displays each selected file with its name, size and page count where available. Use the Up and Down buttons to arrange the files in the required order. Remove any unwanted file, enter a name for the final document, click Merge PDF and download the completed file.
Step by Step Instructions
Step 1: Select Your PDF Files
Click Select PDF Files and choose at least two PDF documents from your device. You can also drag and drop multiple files into the upload area.
