Frequently asked questions
Is there a limit on how many PDFs I can merge?+
No. The only limit is your own machine's memory, since the merge happens in this tab rather than on a server with a quota to enforce.
Does merging reduce quality?+
No. Pages are copied across byte-for-byte, including their text layer, fonts and images. Nothing is re-encoded.
Can I merge password-protected PDFs?+
Not while they're locked. Remove the password in your PDF reader first, then merge.
Are my files uploaded anywhere?+
No. Open your browser's Network tab and merge a file — you won't see it in a request, because there isn't one.
