useforfreeWhat this does
This tool joins PDF files into a single PDF, keeping every page exactly as it was: text stays searchable, links keep working and quality doesn't change. It's handy for combining scanned pages, invoices, or chapters into one document to send or print. Everything runs in your browser using qpdf, a trusted open-source PDF engine, so private documents stay on your device.
How to use it
- Choose your PDFs or drop them onto the box. You can add more at any time.
- Drag the files into order, or use the ↑ ↓ arrows.
- Press Merge PDFs, then download the combined file.
FAQ
Are my PDFs uploaded?
No. The files are merged by your own browser, on your device, and never sent anywhere.
Is there a limit on files or size?
There is no fixed limit. Because everything happens on your device, very large files depend on how much memory your computer or phone has free.
Can I merge password-protected PDFs?
PDFs that only block printing or copying merge normally. If a PDF needs a password to open, remove it first with the Unlock PDF tool, then merge.
