Combine several PDF files into one document, in the order you choose.
Your files are processed inside this browser tab. Pixuna does not upload them to a server.
PDF files. Add two or more and use the arrows to set their order.
Pages are copied from each source file in order. Bookmarks, form fields, and some interactive features may not carry over to the merged file.
Password-protected PDFs must be unlocked first. Use the Unlock PDF tool if you know the password.
Very large files can exhaust browser memory. If a merge fails, try fewer or smaller files.
File handling: This tool runs in your browser. Your PDF is read and processed in the tab on your device, and Pixuna's code does not upload it to a server. You can confirm this in your browser's network panel.
