Merge PDF
Combine multiple PDFs into a single file. Add files, arrange the order with the arrows, then merge.
About this tool
Scanned pages in five separate files, a cover letter here, a CV there — and one upload field that accepts a single PDF. This free tool merges multiple PDF files into one, in exactly the order you choose, directly in your browser. No upload, no account, no watermark, no page limit.
Merging is lossless: pages are copied into the combined document untouched, so text remains selectable and images keep their full quality. And because your documents are processed locally on your device, it's a safe way to combine paperwork you'd never want on someone else's server.
How to merge PDFs
- Drop your PDF files onto the box — add as many as you need, in any order.
- Arrange them with the up/down controls; the numbers show the final order.
- Click Merge and download the combined PDF.
Frequently asked questions
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser — your documents never leave your device, making this safe for contracts, applications and other private paperwork.
Can I change the order of the files before merging?
Yes — every file you add appears in a list with up/down controls, so you can arrange the exact order before pressing merge. The numbering shows the final sequence.
Does merging reduce the quality of my PDFs?
No. Pages are copied into the new document as-is: text stays selectable, links keep working and images keep their original quality. Merging is lossless — the output size is roughly the sum of the inputs.
How many PDFs can I merge at once?
There is no fixed limit — add as many as you need. Very large collections are only constrained by your device's memory.
Can I merge password-protected PDFs?
No — encrypted files cannot be opened by the merger. Unlock them with your PDF software first, then merge the unlocked copies.
