Will merging PDFs reduce their quality?

Absolutely not. Our merge tool concatenates the exact binary data of your PDF pages. It does not compress, alter, or rasterize the content. Text remains selectable, and images retain their original high resolution.

Is it safe to merge confidential documents here?

Yes. PDFNova is the safest option for confidential documents because it is a "client-side" tool. Your files are never uploaded to the internet or stored on any server. The merging happens exclusively inside your own browser window.

Can I merge PDFs on my mobile phone?

Yes! PDFNova is fully responsive and works perfectly on iOS and Android devices. You can select PDFs directly from your phone's file manager or cloud storage (like iCloud or Google Drive) and merge them on the go.
