Is It Private?

Yes. This tool uses the open-source pdf-lib library and runs entirely in your browser. Your PDFs are never sent to any server, logged, or stored.

Are There Size Limits?

There are no server-side limits since everything runs locally. For very large PDFs (100+ MB total), your browser's available memory is the only constraint.
