FAQ
Merge PDF questions
Are my PDFs uploaded to a server?
No. The merge runs in your browser using a local PDF library — documents never leave your device.
How many PDFs can I merge at once?
There is no fixed limit. Capacity depends on your device's memory, since everything is processed locally.
Can I control the page order?
Yes. Reorder the file list with the arrows before merging; pages within each file keep their original order.
Does merging reduce quality?
No. Pages are copied as-is into the new document without re-compression.
