We combine the files locally and hand you a single PDF. Nothing is uploaded.

Frequently asked questions
- Is there a maximum number of files I can merge?
- No. Merge as many PDFs as your device's memory can hold. Most laptops handle dozens to hundreds of files without issue.
- Are my files uploaded to a server?
- No. The merge happens entirely in your browser using WebAssembly. Your PDFs never leave your device.
- Can I reorder pages before merging?
- You can reorder the files themselves before merging. Each file's pages stay in their original order within the final document.
- Will form fields, bookmarks, or signatures survive the merge?
- Page content survives intact. Some interactive features like form fields or digital signatures may not carry over — that's a limitation of merging into a new container, not of this tool.
- Do I need to sign up to merge more than one batch?
- Never. There's no per-day, per-session, or per-account limit. Run as many merges as you want.
