Why use our PDF Merger?

Works entirely offline after loading. No server uploads.

Since processing is local, you avoid standard upload file size limits.

Is there a limit on how many PDFs I can merge?

There is no strict limit, but performance depends on your device's memory. It works best with less than 50 files at once.

Are my PDFs uploaded to a server?

No, our PDF Merger uses WebAssembly (WASM) via Web Workers to process files locally in your browser. Your confidential documents are safe.

Will the original quality be reduced?

No, the merging process preserves the original quality and resolution of your PDF files.
