Frequently Asked Questions
How do I merge PDF files online for free?
Upload two or more PDF files, drag them into the order you want and start the merge. The combined PDF is created instantly in your browser and downloads as a single document — no registration or payment required.
Are my PDF files uploaded to a server?
No. The files are merged locally in your browser and never leave your device, so the tool is safe even for confidential documents.
Can I change the order of the PDFs before merging?
Yes. Drag and drop the uploaded files into any order — the merged document follows exactly the sequence you set.
Is there a limit on the number or size of PDF files?
There is no fixed limit. Because everything runs in your browser, very large files are only limited by your device's memory — typical documents merge in seconds.
