How to Merge PDF Files Online for Free

A step-by-step guide to combining multiple PDF files into one document online — free, private and without installing any software.

Combining several PDFs into a single tidy document is one of the most common file tasks there is — portfolios, invoices, scanned pages, contracts — and it shouldn't require paid software. With Pixelmint.fun's Merge PDF tool, the whole job takes under a minute and happens right in your browser.

Step 1: Open the Merge PDF tool

Go to the Merge PDF tool. You don't need an account, and there's nothing to install. The page works the same on Windows, Mac, Linux, Android and iOS — anything with a modern browser.

Step 2: Add your PDF files

Drag and drop your PDFs onto the upload area, or click it to pick files from your device. You can add as many PDFs as you need, and — importantly — you can reorder them: the tool shows your file list with simple move controls so the final document follows exactly the order you want.

Step 3: Merge and download

Press the Merge button. Within a couple of seconds you'll get a download for your combined PDF. Check the page count in the result panel to confirm everything made it in, then download. That's genuinely all there is to it.

Tips for cleaner merges

  • Name your source files 01-, 02-, 03- before merging so the order is obvious at a glance.
  • Rotate any sideways pages before merging so the final document reads consistently.
  • Merged file too large to email? Run it through a PDF compressor afterwards — 10 MB attachments are a common ceiling.
  • Need the opposite — one PDF split into many? The Split PDF tool extracts exactly the pages you want.

That's the Pixelmint approach in one task: open the tool, drop your files, get a clean result. No watermarks, no sign-ups, no 'upgrade to merge more than 2 files' nonsense.
