PDF tool
Your files never leave your device
Check your Network tab and see
Work starts the moment you drop a file
No daily limit, no sign-up, no watermark
Merging is the PDF operation most likely to involve documents you would rather not hand over — signed agreements, payslips, medical letters, identity documents. The usual free mergers send every file you select to a server, process it there, and hold it for some retention window. This one uses pdf-lib inside the page, so the bytes are read from disk into your own browser tab and the combined file is written straight back out. You do not have to take that on trust: open your browser developer tools, switch to the Network tab, and run a merge. Nothing carrying your documents leaves.
Free PDF mergers commonly gate you after a couple of merges a day, or cap the combined size, and then offer a subscription. There is no such limit here and no account to create, for the straightforward reason that your merges cost us nothing to run — the work happens on your hardware. The only real ceiling is your own device memory, since every document has to be held in RAM while it is combined.
An encrypted PDF cannot be read and recombined without its password, so remove the protection before merging. Preview on macOS, Adobe Acrobat, or the qpdf command-line tool will all do it if you know the password. Files are merged in the order you add them, so add them in the sequence you want the final document to read.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
