Merge PDF
Combine multiple PDF files into a single document. Add your files, drag them into the order you want, and merge — everything happens in your browser, so your PDFs are never uploaded.
How to merge PDF files
Click the box or drag your PDFs onto it to add them. Reorder the files with the up and down arrows so they combine in the right sequence, remove any you don't need, then press Merge PDFs. A single combined PDF downloads instantly. There's no upload, no watermark and no signup.
Merge PDFs privately, in your browser
Most online PDF mergers upload your documents to a server to combine them. This one doesn't — the merge runs entirely on your device using JavaScript, so confidential contracts, statements and scans never leave your computer. That's faster too, because there's nothing to upload or download from a server.
Frequently asked questions
How do I merge multiple PDF files into one?
Add all your PDFs, arrange them in the order you want with the arrows, and click Merge PDFs. The combined file downloads automatically.
How do I combine two PDF files?
Add both files, make sure they're in the right order, and press Merge PDFs — the two documents become a single PDF.
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser, so your documents are never uploaded — ideal for sensitive or confidential files.
Is there a limit on the number or size of files?
There's no signup and no artificial limit. Because everything runs locally, very large files use your device's memory, but typical documents merge in seconds.
Will the merged PDF have a watermark?
No. The combined PDF is clean, with no watermark and no quality loss.
