PDF Merge

Merge PDF files online — free and private

Combining several PDFs into one file used to mean installing software or handing your documents to a website that uploads them to its servers. This tool does it differently. Everything happens right in your browser — the PDFs you pick never leave your device, never touch a server, and aren't stored anywhere. You drop in your files, arrange them, merge, and the finished document is yours. No account, no upload, no waiting in a queue.

That matters more than it sounds. The files people merge are often the private ones: signed contracts, bank statements, medical records, scanned IDs. Sending those through someone else's server is a risk most of us would rather skip. Here there's nothing to leak, because nothing goes anywhere.

What you can do

Add as many PDFs as you need and combine them into a single document in the order you want. Each file shows up in a list, and you can move any of them up or down with the arrows until the sequence is right — the cover letter first, the appendix last, whatever the job calls for. Don't need a file after all? Remove it from the list with one tap before you merge.

The pages themselves are copied across exactly as they are. There's no re-compression and no quality loss — the text stays sharp, the images stay as crisp as the originals, and a merged file looks identical to the documents that went into it. If one of the files you add happens to be corrupted or unreadable, the tool simply skips it and tells you which one was left out, instead of failing the whole job.

Works on your phone

The whole thing runs on your phone the same way it runs on a computer — no app to install. Pick PDFs straight from your iPhone or Android, reorder them with a tap, merge, and share the result wherever you need it. For a lot of people the documents that need merging are already sitting on their phone, so being able to finish the job there without emailing files back to a laptop is the whole point.

How to merge PDFs

Add the PDF files you want to combine. Put them in order using the up and down arrows, and remove any you've changed your mind about. When the list looks right, merge — the combined PDF is ready in a moment, and you can download it or share it straight away.

How it compares to other tools

Most online PDF mergers work by uploading your files to a server, doing the work there, and sending the result back. Some cap how many files you can merge for free, some add a watermark, some ask you to sign up first. This one has none of that: no upload, no file limit, no watermark, no account. It works on whole files — it combines complete PDFs rather than pulling out or rearranging individual pages — and it doesn't shrink the file size. If your combined PDF ends up larger than you'd like, say for emailing, you can run it through the PDF Compressor afterwards to bring the size down. For a straightforward "join these documents into one," merging on its own is exactly what most people want. Need to go the other way and break a PDF apart? The PDF Split tool divides one into equal parts or page ranges, also in your browser.

Common uses

People merge PDFs for all kinds of everyday reasons: putting a multi-part report back into a single file, combining scanned pages of a contract, bundling receipts or invoices for an expense claim, joining a cover letter with a CV, or gathering a set of forms into one document before sending it on. Anything that arrived as separate PDFs but needs to travel as one.

Frequently asked questions

Are my files uploaded to a server?

No. The merging happens entirely in your browser, on your own device. Your PDFs never leave your computer or phone, and nothing is stored or sent anywhere.

How many PDFs can I combine?

There's no fixed limit — add as many files as you need. Very large batches depend on your device's available memory, since all the work is done locally.

Will merging reduce the quality of my PDFs?

No. Pages are copied across exactly as they are, with no re-compression. The merged file looks identical to the originals.

Can I change the order of the files?

Yes. Each file in the list can be moved up or down with the arrows, so you control exactly how the final document is arranged before you merge.

What happens if one of my files is broken?

If a PDF can't be read, the tool skips it and tells you which one was left out, then merges the rest. One bad file won't stop the whole job.

Does it work on mobile?

Yes. It runs in your phone's browser with no app to install — pick your files, reorder, merge, and share, all from your device.
