Informazioni su questo strumento

Combine two or more PDF files into a single document - keep page order, preserve quality, and never upload anything. The merge happens entirely in your browser using pdf-lib, so even confidential contracts, scans, and invoices stay on your device.

Useful when you need to send a single packet to a client, bundle scanned receipts for an expense report, or stitch together multiple chapters into one book.

Come si usa

Tutto avviene all'interno del tuo browser con JavaScript e WebAssembly. I tuoi file non vengono mai caricati su un server, mai memorizzati e mai visti da noi.

Domande frequenti

Is there a file size or page limit?

No artificial limit. The only limit is the RAM available to your browser tab - modern laptops handle hundreds of pages easily.

Do my PDFs get uploaded to a server?

No. The merge runs locally in JavaScript. Your files never leave the browser tab.

Will the merged file lose quality or formatting?

No. We copy the original pages byte-for-byte; fonts, images and vector graphics are preserved.
