FAQ
Are my PDF files uploaded to a server?
No. Merging happens entirely in your browser using JavaScript — your files never leave your device, and the tool even works offline.
Can I merge only some pages from each PDF?
Yes. Each file has an optional page-range field. Enter ranges like 1-3, 5, 8-10 to include only those pages — you can even repeat pages (e.g. 1,1) to duplicate them.
Can I change the order of the merged files?
Yes. Use the up/down arrows on each file to reorder before merging. Pages appear in the output in exactly the order shown.
Is there a file size or count limit?
There is no hard limit — it depends on your device's memory. Merging dozens of typical PDFs works fine on most modern devices.
