Merge PDF Tool: A merge PDF tool combines several PDF files into one document in the order you choose. Add your PDFs, drag to reorder, and download a single merged file — processed in your browser so nothing is uploaded.
Frequently Asked Questions
How do I merge PDF files?
Upload two or more PDFs, drag them into the desired order, and click Merge. The tool joins them into one continuous document you can download immediately.
Can I reorder pages before merging?
You can reorder the files before merging. Arrange the documents in the sequence you want and the merged PDF follows that order.
Are my PDFs uploaded to a server?
No. Merging is performed locally in your browser using pdf-lib, so your documents never leave your device — ideal for confidential files.
Is there a limit to how many PDFs I can merge?
There is no fixed limit for typical use. Very large or numerous files depend on your device's available memory since processing is done locally.
How do you merge PDF files?
Merging PDFs combines several PDF files into one document in an order you choose, keeping every page's text, links and layout intact.
SnoopTool merges PDFs entirely inside your browser using pdf-lib, so contracts, ID scans and bank statements are never uploaded to any server. There is no page limit, no watermark and no email wall.
