# How to Merge PDF Files Online — Fast & Free

## Why merge PDFs?

Whether you're combining reports, joining scanned pages, or assembling a proposal from multiple sources, merging PDFs is one of the most common document tasks. Instead of installing desktop software, you can do it instantly online.

## How to merge PDF files with PDF Genie

Combining PDFs takes less than 30 seconds:

1. **Go to [Merge PDF](/merge-pdf)** on PDF Genie
2. **Drag and drop** your PDF files into the upload area (or click to browse)
3. **Reorder** the files using the ↑ and ↓ arrows if needed
4. **Click "Merge PDFs"** — your combined file downloads instantly

That's it. No account, no watermarks, no waiting.

## Tips for better results

- **File order matters** — arrange your PDFs in the sequence you want before merging
- **There's no file limit** — you can merge 2 or 200 PDFs at once
- **Your files stay private** — merging happens entirely in your browser. Nothing is uploaded to any server
- **Works on any device** — phone, tablet, or desktop. No app needed

## What about file size?

Free users can merge files up to 50 MB each. If you regularly work with larger files, [PDF Genie Pro](/pricing) supports files up to 200 MB with no daily limit.

## Common use cases

- **Students** — combining assignment pages, research papers, or lecture notes
- **Business** — merging contracts, invoices, or multi-part reports
- **Legal** — assembling case documents or exhibits in order
- **Personal** — joining scanned receipts, tax forms, or travel documents

## Can I merge different file types?

PDF Genie's merge tool works with PDF files only. If you have Word documents or images, first convert them to PDF using our [Word to PDF](/word-to-pdf) or [JPG to PDF](/jpg-to-pdf) tools, then merge.
