PDF Merger
Combine multiple PDF files into one document, in any order you choose.
Files are merged entirely in your browser — nothing is uploaded anywhere.
Combine multiple PDF files into a single document in whatever order you choose — reordering pages before merging, without needing separate PDF editing software or an online upload service.
Merging happens entirely in your browser, so the files never leave your device — useful when the documents contain anything sensitive.
Frequently asked questions
- Is there a limit to how many PDFs I can merge?
- You can merge as many files as your browser's memory comfortably handles; very large batches of large PDFs may be slower depending on your device.
- Are my files uploaded to a server?
- No — the merge happens locally in your browser using client-side processing, so your documents are never uploaded anywhere.
- Can I reorder pages before merging?
- Yes — drag files into the order you want before merging; the final document follows that exact sequence.
