Categories: pdf-tools
Privacy: Your PDFs are merged locally in your browser and never uploaded.

## About

Join two or more PDFs into a single file. Pages are copied in the order you add the files, so you control the final sequence. Bookmarks and forms are flattened to plain pages.

Merging runs entirely on your device — ideal for contracts, reports, and any document you would rather not upload.

## How to use

1. **Add PDFs in order** — Two or more; they merge in the listed sequence.
2. **Merge and download** — The combined PDF is ready in seconds.

## FAQ

### Are pages reordered or lost?

No. Every page from every file is copied, in order, into the output.

### Do encrypted PDFs work?

Password-protected PDFs are loaded with encryption ignored where possible; a file that cannot be opened will report a clear error.

### Is the upload secure?

There is no upload. The PDFs are read from your device, merged in the browser, and the result is downloaded. Nothing leaves your device.

### Is there a size limit?

The tool runs entirely in your browser, so the practical limit is your device memory. Files under 100 MB work on most laptops; multi-gigabyte files may exhaust memory on lower-end devices.
