Notes

This tool merges PDFs entirely in your browser using pdf-lib. No files are uploaded to a server. For best results keep files under 10MB each — large PDFs may be memory-intensive in the browser.

If you don't have pdf-lib installed in your project, install it with your package manager so the dynamic import can resolve at runtime.
