Frequently Asked Questions
Is there a limit on file size or quantity?
Our tool relies on your device's memory. While there is no hard limit imposed by us, extremely large files or hundreds of documents might slow down your browser.
Are my documents safe?
Yes. Unlike other services, we do not have a backend server storing your files. Everything is processed via Javascript inside your active browser session.
Can I merge encrypted PDFs?
Currently, heavily encrypted PDFs requiring passwords cannot be merged directly. Please remove the password protection before using this tool.
