Download merged.pdfWhat works offline
Once this page has finished loading, merging does not need a connection. We tested it in Chromium with the network switched off: choosing files, merging and downloading merged.pdf all worked. Your files are not uploaded either way, online or offline.
How to get ready
- While you are still online, open this page and wait until the Choose files button is on screen.
- Leave the tab open. Do not close it and do not reload it.
- Switch off the network, or move to where there is no signal. The page keeps working, because the merging code is already in your browser.
- Press Choose files, put the files in order, press Merge PDFs, then press Download merged.pdf.
What stops working offline
- Loading the page. It will not load at all if you were never online with it. If you close the tab, or reload it while offline, do not count on getting it back.
- The Pro check. Pro needs a connection to be checked, so plan on the free limits while offline: up to 5 files and 20MB in total per merge.
What this does not do
It is not an installed app, so closing the tab ends the offline option until you are online again. We tested Chromium only; other browsers may behave differently, so try yours once before you rely on it. The merge itself is the usual one: whole files in the order you choose, no compression, no editing. Here is how to check for yourself that nothing is uploaded.

Free, with an optional Pro unlock
Pro is Hexloom Pro, $29 a year or $4 a month, one subscription for every Hexloom tool. It removes the 5 file and 20MB limits. There is no account: Pro unlocks the browser you subscribe in, and the confirmation page has a link to restore it elsewhere.
