Is it safe to merge confidential PDFs here?

Yes. The merge happens entirely in your browser — your PDFs are never uploaded to any server. You can disconnect from the internet after the page loads and the tool keeps working.

Is there a limit on file count or size?

No fixed limits. Merge as many PDFs as you like — the only practical constraint is your device’s memory.

Will the merged PDF keep its quality?

Yes. Pages are copied over exactly as they are — no re-compression, no watermarks, no quality loss.

Can I merge password-protected PDFs?

Encrypted PDFs can’t be read without their password, so they are skipped with a clear message. Remove the password first, then merge.
