🔗Merge PDF Files — Free & Private

Need to combine a contract, its annexes, and a signed cover page into a single file? Drop your PDFs below, drag them into the right order with the arrow buttons, and click Merge — you get one clean PDF in seconds.

Unlike iLovePDF, Smallpdf, or Adobe's online tools, PrivtePDF never uploads your documents. The merging happens entirely inside your browser using JavaScript, so invoices, medical records, and legal paperwork stay on your device from start to finish. There is no server that could store, scan, or leak a copy.

There's no cap on how many PDFs you can combine and no artificial size limit — because nothing travels over the network, the only limit is your device's memory. The merged file downloads instantly with no watermark and no account required.

How to merge PDF files

  1. 1Drop two or more PDF files into the box below (or click to browse).
  2. 2Reorder them with the up/down arrows — the final PDF follows this order.
  3. 3Click “Merge PDFs” and the combined file downloads automatically as merged.pdf.
What gets preserved

Every page is copied at full quality — text, images, and vector graphics are untouched. Interactive extras like bookmarks and form fields from the source files are not carried over, which keeps the output small and predictable.

Frequently asked questions

Is it safe to merge PDFs online?

With PrivtePDF, yes — because your PDFs are never actually sent anywhere. The merge runs locally in your browser; you can even disconnect from the internet after the page loads and it still works.

Does merging reduce the quality of my PDFs?

No. Pages are copied losslessly into the new document. Text stays selectable and images keep their original resolution.

How many PDF files can I merge at once?

There is no fixed limit. Since processing is local, you can merge dozens of files — very large jobs are only bounded by your device's available memory.

Can I change the order of the files before merging?

Yes. After adding files, use the ▲ and ▼ arrows next to each file to arrange them. The merged PDF follows exactly that order.
