Why merge in the browser?
Most online PDF mergers upload your documents to a server, where they could be stored or seen by others. That's risky for contracts, statements and anything personal. This tool uses the open-source pdf-lib engine to combine your files entirely on your device — nothing is transmitted, so your documents stay completely private.
Are my PDFs uploaded anywhere?
No. The merging happens locally in your browser. Your files never leave your computer.
Is there a file size or page limit?
There's no fixed limit — it's bounded only by your device's memory. It handles typical multi-page documents easily.
Will it keep my formatting and images?
Yes. Pages are copied exactly as they are, preserving text, images and layout.
