Merge PDF files online, free
Contracts in three attachments, a report split across downloads, boarding passes scattered through your inbox — reuniting them shouldn't require an account, a subscription, or uploading sensitive documents to a stranger's server. Drop up to thirty PDFs below, drag them into order, and download a single combined file. Pages carry over exactly as they were, and everything happens locally in your browser.
How to merge PDFs
- 1Drop two or more PDFs on the merger above. Each file lands in the list with its page count.
- 2Reorder with the arrows until the document reads correctly from first page to last.
- 3Hit Merge PDFs and download. One file, every page in order, ready to send or archive.
Clean merges
Order first, merge once
Double-check the sequence in the list — re-splitting a merged file to fix one swapped document wastes a round trip.
Name files clearly first
"contract-final.pdf" beats "scan(3).pdf" when you're arranging ten look-alike attachments.
Huge file after merging?
Merging preserves original quality, so big inputs make big outputs — run the result through the compressor if it must travel by email.
Frequently asked questions
How do I merge PDF files for free?
Drop them above, arrange the order, hit Merge PDFs. The combined file downloads immediately — no accounts, no uploads.
How many PDFs can I combine?
Up to thirty files per merge — plenty for reports, applications, and records bundles.
Will merging change quality?
No. Pages are copied into the new file exactly as they were, with no re-rendering.
Can I merge password-protected PDFs?
Only if they open without a password. Locked files must be unlocked first.
Are my documents uploaded?
Never. Merging runs 100% in your browser — sensitive paperwork stays private.
