A common scenario

You are on the bus and need to combine three PDF attachments from Gmail into one file before forwarding them to a colleague.

Why privacy matters here

Free Android PDF apps often upload to a server or require sign-in. DukPdf keeps the merge inside the browser on your phone, so the documents never leave your device.

Configure the operation

Pick a quality preset, page range, signature style, or whatever the tool needs. Every option runs in your browser — nothing is sent to a server.

Every step runs in your browser. No server uploads, no waiting.

Merge PDF on Android — questions

Do I need to install a PDF app on Android to merge?

No. DukPdf runs in your phone browser. Open the Merge PDF page, pick the PDFs, and download the combined file — no install and no permissions beyond what the browser already has.

Which Android browsers are supported?

Chrome, Samsung Internet, Firefox, Edge, Brave, and any other modern Android browser. The page is touch-optimized for one-handed use.

Will merging reduce quality?

No. The merge only rearranges pages and copies streams — it does not re-render or recompress. Output pages are byte-identical to the input.

Are my PDFs uploaded?

No. The merge runs locally in the browser. Once the page has loaded, you can disconnect from the internet and continue to use the tool — the merge itself never touches a server.
