About This Tool
Combining multiple PDF files into a single document is a common need for professionals, students, and anyone who works with digital documents. Whether you are assembling a report from separate chapters, merging signed contracts, or consolidating invoices for accounting, our free online PDF merger makes it simple to combine files without installing expensive desktop software. Just upload your PDFs, arrange them in the desired order, and download the merged document instantly.
The tool gives you full control over the page order with an intuitive drag-and-drop interface. You can reorder files before merging, and the merged PDF preserves all formatting, fonts, images, and links from the original documents. There is no limit on the number of files you can merge in a single operation, making it suitable for everything from combining two simple forms to assembling a comprehensive multi-document package.
All processing happens entirely in your browser using client-side PDF manipulation technology. Your documents never leave your device — they are not uploaded to any server or cloud storage. This ensures complete privacy and security for sensitive documents like legal contracts, financial statements, medical records, and confidential business proposals. The tool is free to use, requires no registration, and works on any modern browser.
How to Use This Tool
Upload Your PDF Files
Drag and drop multiple PDF files onto the upload area or click to browse your files. You can select several files at once from your computer. All uploaded files appear as thumbnails in the merge queue.
Arrange the Order
Drag the file thumbnails to reorder them as needed. The files will be merged in the order shown, from top to bottom. The page count for each document is displayed to help you verify the arrangement.
Merge the Documents
Click the merge button to combine all the PDFs into a single document. The tool processes the files locally in your browser and creates a new merged PDF that includes all pages from every uploaded file.
