About merge pdf

Need to combine PDF files quickly without uploading anything? This free merge tool joins as many PDFs as you like into one document, right in your browser. Drag the files into any order before you download — there's no page limit beyond your device's memory.

Because the merge happens locally, it's a safe way to combine confidential contracts, invoices or scanned records: the files are never sent to a server. It works the same on Windows, Mac, Chromebook and mobile, with no account and no watermark.

Questions, answered

Q.Is there a file size or count limit?

No artificial limits — you are bound only by your device's memory. You can merge dozens of PDFs at once.

Q.Can I reorder the PDFs before merging?

Yes. Drag the files into any order before you click Merge, and the combined document follows that order.

Q.Are my files uploaded to a server?

No. Every operation runs entirely in your browser using JavaScript, so your files never leave your device. Open your browser's Network tab and watch — nothing is sent or stored.

Q.Is it free? Do I need an account or to install anything?

It's completely free with no sign-up, no email and nothing to install. There are no daily limits and no watermarks on your output.

Q.Does it work on Mac, Windows, Chromebook and phones?

Yes. It runs in any modern browser — Chrome, Edge, Firefox or Safari — on Windows, macOS, Linux, Chromebook, iPhone and Android. There is nothing to download.
