Combining PDFs usually means handing a stack of documents — invoices, contracts, scans — to someone else's cloud. Kameleo merges them locally instead. Add as many files as you like, drag them into the order you want, and export a single PDF without a byte leaving your device.

Because there is no upload, there is nothing to store, leak, or mine. It is faster too: no waiting for a round-trip to a server and back, and no watermark stamped on the result.

Nothing uploaded

Every file is combined in your browser. Sensitive documents never touch a server you don't control.

Drag to reorder

Arrange pages and files visually before you merge, so the final document comes out in exactly the right order.

No watermark

The merged PDF is clean and unbranded — no forced logo, no account, no email required to download.

Instant, offline-capable

No upload round-trip means merging is near-instant, and it keeps working even on a flaky connection.

How to merge pdf in three steps

  1. Drop in all the PDFs you want to combine — add as many as you need.
  2. Drag the files into the order you want them to appear in the final document.
  3. Click Merge and download your single combined PDF — no upload, no watermark.

Frequently asked questions

Is merging PDFs free?

Yes, free with a daily task limit on the free plan. No watermark is added and no account is needed to download the combined file.

Are my documents uploaded anywhere?

No. Merging happens entirely in your browser. You can verify in the Network tab that no file data leaves your device.

Can I reorder the files before merging?

Yes. Drag the files (and pages) into any order before you export, so the combined PDF is arranged exactly as you want.

How many PDFs can I combine at once?

You can add many files in a single merge. Very large combined outputs are subject to the free plan's 50 MB per-file guidance; paid plans lift the limits.

Will the quality or formatting change?

No. Merging preserves each page exactly as it was — text stays selectable and images stay at their original resolution.

Does it work offline?

Once the page has loaded, merging runs locally, so it keeps working even if your connection drops.
