자주 묻는 질문

Is there a limit on the number of files?

No hard limit. You can merge as many PDFs as your browser memory allows. For very large collections (50+ files), processing may take a few extra seconds.

Are my PDFs uploaded to a server?

No. All merging is done locally in your browser using the pdf-lib library. Your documents never leave your device.

Does merging preserve formatting?

Yes. The tool copies pages directly without re-rendering, so fonts, images, and layouts are preserved exactly.
