PDFTeq Merge PDF: combine PDFs in your browser, no upload
Merge two or more PDFs locally in your browser with pdf-lib: no upload, no sign-up, no watermark, and page quality left untouched.
About PDFTeq Merge PDF
PDFTeq's Merge PDF does one job without sending your files anywhere. You pick two or more PDFs, your browser combines the pages into a new document, and you download it. It uses pdf-lib, an open-source JavaScript library, to read the files into your browser's memory and copy their pages across. There is no sign-up and no watermark.
The page invites you to check the privacy claim yourself: open your browser's developer tools, watch the Network tab while you merge, and you will see no upload of your PDF. Because pages are copied as they are rather than re-rendered or compressed, quality stays the same. Once the page has loaded, the merge works without an internet connection.
There are a few honest limits. Pages follow the order in which you select the files, and drag-to-reorder is not supported yet, so pick them in the right sequence. Very large files of a gigabyte or more depend on your device's memory, and password-protected PDFs need unlocking first.
It is part of PDFTeq, a suite of 22 PDF tools, most of which run locally (the site marks the server-assisted ones), plus a set of financial calculators aimed at Indian users, such as EPF and MSME loan calculators.
