Frequently asked questions
Does this really work with no internet connection?
Yes — once this page has loaded, merging works with your Wi-Fi off or in airplane mode. Load the page, disconnect, then merge, to see for yourself.
Why would I want an offline PDF merger?
Total privacy (nothing can be uploaded if there's no connection), and it keeps working on a plane, on a slow connection, or on a locked-down network.
Is this the same tool as the regular merge page?
Yes, same code — this page just makes the offline guarantee explicit, since it's exactly what "offline" tools should mean.
