FAQ
Frequently Asked Questions
Common questions about merging PDF files online.
Are my PDF files safe when I merge them?
Yes, completely. All merging happens in your browser using JavaScript. Your files are never uploaded to any server and remain fully private on your device.
Can I merge password-protected PDFs?
This tool works with unlocked PDFs. If your file is password protected, use the Unlock PDF tool first to remove the password, then merge.
Is there a limit on how many PDFs I can merge?
There is no hard limit set by the tool. You can add as many files as needed, though very large batches may use more browser memory and take longer on older devices.
Can I change the order of the PDF files before merging?
Yes. After uploading, drag the files in the sidebar list into your preferred order. The preview updates in real time to reflect the new arrangement.
Does this tool work on mobile devices?
Yes, the tool is responsive and works on modern mobile browsers. For large PDFs or many files, a desktop browser is recommended for better performance.
