Merge PDF

Combine several PDFs into one file — add them in the order you want, keep every page, and download. It all runs in your browser, so your documents never leave your device.

Short answer

To merge PDFs, add two or more files below in the order you want them joined — every page is kept at full quality and combined into a single PDF you can download. It's free, has no watermark, and runs entirely on your device.

Frequently asked questions

Related tools

Are my PDFs uploaded when I merge them?+

No. This tool merges your PDFs entirely in your browser using JavaScript — the files are read and combined on your own device and never sent to a server. That makes it safe for confidential documents and it keeps working even offline once the page has loaded.

How do I combine PDF files in order?+

Add the PDFs in the sequence you want them joined — they're merged top to bottom in that order, with every page preserved. Add them one batch at a time if you need precise control over ordering.

Is there a limit on how many PDFs I can merge?+

There's no fixed limit — it depends on your device's memory. Because the merge happens locally, dozens of ordinary documents combine quickly without an upload wait.

Will merging change the quality or layout of my PDFs?+

No. Pages are copied as-is into the combined file, so text stays selectable, images keep their resolution, and each page keeps its original size and orientation.

Is it free and watermark-free?+

Yes — no signup, no email, no watermark, and no per-file limit. The tool is ad-supported, and since it runs in your browser there's no per-merge server cost to gate.

Your PDFs are combined entirely in your browser and are never uploaded to a server. Provided free and ad-supported, without warranty; check the merged file before relying on it.
