How Merge PDF Works

Merge PDF is a free online tool that combines multiple PDF files into a single document in seconds. Whether you are joining scanned contracts, collecting report chapters, or bundling presentation slides from different sources, everything is processed locally in your browser — no files are ever uploaded to a server.

Drag to reorder files and select only the pages you need from each one

  1. Click the upload area and select two or more PDF files (or drag them in directly). Images are also accepted and will be converted to PDF automatically.
  2. Arrange the files in the order you want them to appear — drag any file up or down, or use the selectors to reorder.
  3. Optionally expand a file to choose only specific pages from it.
  4. Click "Merge & Download" and your combined PDF will be ready in moments.

Typical Use Cases

Combine contract packages

Sales and legal teams merge a contract, its appendix and signed pages into one file before sending it to a client.

Bundle report chapters

Freelancers combine a cover page, body chapters and an appendix into a single deliverable PDF without re-exporting.

Collect scanned pages

Batch-scan a multi-part document and merge the separate PDFs from the scanner into one complete file.

Merging is especially useful when a client sends you a multi-part document: feedback rounds, appendices and cover pages can all be combined into one clean file before you send it back. Because processing happens locally, confidential contracts never leave your device.
