About this tool

Add several PDFs, re-arrange their order with up/down controls, and merge them into a single PDF right in your browser.

PDF Merge is a fast, intuitive tool that combines multiple PDF documents into a single, unified file. Whether you're consolidating separate chapters of a report, combining invoices and receipts, merging signed and unsigned document versions, or assembling a complete document from multiple sources, this tool makes the process effortless. Simply upload your PDFs, arrange them in your desired order, and download the merged result—all from your browser with zero uploads to external servers.

The tool preserves the quality, formatting, and structure of every input document in the final merged PDF. It handles PDFs of any size and number, supports drag-and-drop reordering, and maintains bookmarks and internal links where possible. From students combining assignment sections to professionals assembling complete document packages, PDF Merge is the quickest way to bring multiple PDFs together into one cohesive file.
