Frequently Asked Questions

1

Is it really free to merge PDFs?

Yes — 100% free. No signup, no watermarks, no limits. Everything runs in your browser — no server upload ever.

2

Are my files secure and private?

Absolutely. Your files never leave your device. All processing is local — no data sent to any server. Complete privacy, guaranteed.

3

How many PDFs can I merge at once?

There's no hard limit. We use parallel processing so even large batches (50+ files) complete in seconds. Only your browser memory limits you.

4

Does merging reduce PDF quality?

No. We copy pages without re-encoding — fonts, images, vector graphics and formatting stay exactly as-is. Zero quality loss.

Yes! Drag and drop files to reorder, or use the up/down arrow buttons. The preview number updates in real time.
