Frequently asked questions

Q. Is there a file size or page limit?
No fixed limit. Because merging happens in your browser, very large files (hundreds of MB) depend on your device's memory.
Q. Can I merge password-protected PDFs?
Not yet. Remove the password in your PDF reader first, then merge.
Q. Are my files uploaded?
No. The PDF is built with pdf-lib in your browser and nothing is sent to a server.
