About the PDF Merger

Our free PDF merger lets you combine multiple PDF files into a single document in seconds, directly in your browser. Upload your files, reorder them using the arrow buttons if needed, and click Merge — your combined PDF downloads instantly.

This is useful in a wide range of situations: combining a multi-chapter report into one file, merging separate invoice pages, joining scanned documents, or combining a cover letter and CV before sending an application. Instead of installing desktop software, just open this page and merge.

The tool shows the page count for each PDF you upload so you always know what you're working with. Files are listed in merge order — number 1 becomes the first section of the output, number 2 comes next, and so on. Use the up and down arrows to rearrange them before merging.

All processing happens locally using the open-source pdf-lib library. Your PDF files are never uploaded to any server — they stay on your device the entire time.
