Frequently asked questions
How do I merge PDF files?
Drag and drop two or more PDFs onto the tool, drag them into the order you want using the up and down buttons, then click Merge PDFs. A single combined PDF is generated instantly and ready to download.
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser using JavaScript. Your files never leave your device, which keeps confidential contracts, invoices and scans completely private.
Can I change the order of the files?
Yes. Each file appears in a list with up and down controls so you can arrange them precisely. The final PDF follows the order shown, top to bottom.
Is there a limit on the number or size of PDFs?
There is no fixed limit, but because everything runs in your browser the practical ceiling depends on your device's memory. Very large files may take a few seconds to process.
Does merging reduce quality?
No. Pages are copied exactly as they are, so text stays selectable and images keep their original resolution. Merging never re-compresses or degrades your content.
