Merge PDF Files

Combine several PDF files into a single document in the order you choose. The merge happens in your browser, so your files are never uploaded.

Your file never leaves your device.

How to convert PDF to PDF

Add two or more PDFs, arrange them in the order you want and download one merged PDF. Pages are copied as they are, so text stays selectable, links keep working and quality is untouched. Contracts with annexes, scanned pages, invoices for accounting or chapters of a thesis all become one tidy file.

Step 1: Add your PDF files
Drag and drop a .pdf file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Set the order
Move files up or down until they are in the right order.
Step 3: Merge and download
Download a single PDF that contains every page.

About the formats

What is PDF?

PDF (Portable Document Format) reproduces a document exactly as it was laid out, regardless of the device, operating system or software used to view it. It is the standard choice for sharing, printing and archiving documents whose appearance must not change. Text-based PDFs can be converted to Markdown, plain text or HTML here.

Use PDF whenever the layout matters more than editing, reports, invoices, contracts, résumés and anything you need to share or print so it looks identical everywhere. Choose PDF when recipients should see exactly what you saw, with no fonts or margins shifting.
