How to use this tool

  1. Add two or more PDFs

    Drop the files onto the box or tap to pick them on your phone. Each card shows the file's page count and size, read on your device.

  2. Drag them into order

    Drag the cards (or use the arrow buttons) until the files sit in the order the merged document should read.

  3. Merge and download

    Tap Merge and the combined PDF downloads instantly — pages are copied losslessly, nothing is recompressed.

Questions people ask

Is it safe to merge PDF files online?

Here, yes — this merger runs entirely in your browser. Your PDFs are never uploaded to any server, which matters when the files are rental agreements, salary slips or ID documents that you would not hand to a random website.

How do I merge PDF files for free without software?

Open this page, drop your PDFs, drag them into order and click Merge — no install, no signup, no watermark, no page limit.

Can I merge PDF files without internet?

Yes — once the page has loaded, merging works fully offline, because all processing happens on your device.

Is there a file size or page limit?

No hard limit. The practical ceiling is your device's memory — a few hundred megabytes merges fine on most modern phones and laptops.

Can I reorder pages while merging?

You can reorder whole files here. For page-level control — moving, rotating or deleting individual pages — use our Organize PDF tool after merging.

Does merging reduce quality?

No. Pages are copied losslessly into the new file; nothing is re-rendered or recompressed, so every page stays pixel-identical.

What about password-protected PDFs?

A locked file cannot be read without its password, so the tool flags it on the file card instead of failing the whole merge. Unlock it in any PDF viewer (open, enter the password, Save As) and add it again.
