A: Hi, yes, UPDF supports combining multiple PDF files. You can use our Merge feature. In UPDF Home, click the Tools button at the bottom to find the Merge function. UPDF also supports reading PDFs. You can add annotations, notes, or change the background style to make reading more comfortable.

If you have any other questions, please feel free to contact our support team at [email protected]. Thank you for your support and understanding.
