Are my PDFs uploaded?

No. Files are merged locally in your browser. Only the small open-source pdf-lib script is downloaded to do the work.

Can I merge password-protected PDFs?

No. Protected or damaged files cannot be read, and the tool will tell you which file caused the problem. Remove the password first.

Is there a page or file limit?

There is no fixed limit, but very large files depend on your device's memory because everything is processed in the browser.

Does merging reduce quality?

No. Pages are copied as they are, without re-compressing text or images.
