Frequently asked
Are my files uploaded anywhere?
No. The merge happens entirely in your browser using JavaScript — your PDFs never touch a server. You could disconnect from the internet after this page loads and it would still work.
Is there a file size or count limit?
No artificial limit — only the memory of your own device, which for typical documents means dozens of files without issue.
Does this work on password-protected PDFs?
Not currently — remove the password first using your PDF viewer, then merge here.
