Need to combine several PDF documents into one? Whether you're assembling a report, packaging invoices, or combining chapters, merging PDFs takes about 10 seconds when you use the right tool.

How to merge PDFs in 3 steps

Go to RizzPDF Merge PDF
Drop your PDF files onto the page — drag to reorder them
Click Merge PDFs and download your combined file

That's it. No account, no email, no software to install.

Are my files safe?

Yes — because they never leave your device. RizzPDF runs entirely in your browser using JavaScript. Your PDFs are processed locally and never uploaded to any server. This makes it safe for sensitive documents like contracts, financial statements, or medical records.

How many files can I merge for free?

The free tier allows up to 3 files per session. If you need to merge more, a $1 day pass gives you unlimited merges for 24 hours. Pro subscribers ($5/month) get unlimited everything, always.

Can I reorder pages before merging?

Yes. After uploading your files, drag them into the order you want before clicking Merge. Each file becomes a section in the final PDF in the order you specify.
