About the Merge PDF tool
Merging PDFs is handy when you need to send one file instead of many — like combining a cover letter with a résumé, or joining monthly statements into one record. Pages are copied exactly as they are, so text stays sharp and searchable and formatting is kept.

Frequently asked questions
Is there a limit on how many PDFs I can merge?
There's no fixed limit. Because merging happens in your browser, the maximum size depends on your device's memory.
Will the quality change?
No. Pages are copied without being re-compressed, so the merged PDF looks exactly like the originals.
Can I merge password-protected PDFs?
Encrypted PDFs can't be merged. Remove the password first, then try again.
Are my files safe?
Yes. Your PDFs never leave your device — they are combined right in your browser.
