Built differently: the file never leaves your hands

On most PDF websites, your document is uploaded to a company server, processed there, and kept for a while before deletion. Here, the tools run as code inside your own browser tab. You can even turn off your internet after this page loads and every tool still works. Because the work happens on your device, very large files may be slow or run out of memory on a phone - a computer handles those best.

Nothing is uploaded

Your PDF is read and rewritten by your own device. No server ever sees it, stores it, or scans it.

Fast, with no queue

No upload wait, no processing line and no daily cap. There are no artificial limits - processing runs on your device, so very big files work best on a computer and finish as fast as your device can work.

No accounts, ever

There is nothing to join and no email to hand over. Open a tool, drop your file, download the result.

      How to merge PDF files into one

      Merging is the fix whenever life hands you a document in pieces: a contract in three scans, certificates saved one per file, a form plus its attachments. Portals, employers and teachers almost always want one file, in the right order. A good merge should be lossless - pages copied exactly, nothing re-rendered or blurred - which is how our Merge PDF tool works.

      Before you merge, a minute of tidying pays off. Rotate sideways pages upright, delete blank scanner pages, and name your files in order (01, 02, 03) so arranging them is drag-and-drop instead of guesswork. If the combined file then passes a portal size cap, compress the merged PDF to the exact target afterwards.

      How to do it

      1. Gather the PDFs and fix sideways or blank pages first.
      2. Open Merge PDF and add the files.
      3. Drag them into the order you want.
      4. Click Merge and download the combined PDF.
      5. If it is over a size cap, run it through Compress PDF with that exact target.

      Common questions

      Does merging reduce quality?

      Not here. Pages are copied losslessly into the new file, so text and scans stay exactly as they were.

      How many files can I merge?

      There is no coded limit - the practical limit is your device's memory. Everyday documents merge easily; hundreds of pages are smoother on a computer.

      Are my files uploaded?

      No. Merging happens in your browser.
