Frequently asked questions
Can I change the order of the files?
Yes. Drag any file up or down in the list before you merge. Pages are combined in the order shown.
Is there a limit on how many PDFs I can merge?
No fixed limit. Very large sets are limited only by your device’s memory, which is usually hundreds of pages or more.
Will the merged PDF keep the original quality?
Yes. Pages are copied as they are, so text stays selectable and images keep their resolution.
Are my files uploaded anywhere?
No. The whole tool runs inside your browser using JavaScript. Your files stay on your device, nothing is sent to a server, and nothing is stored. You can even use it offline once the page has loaded.
Is it really free?
Yes. There is no account, no watermark, no file-size tier and no daily limit. Use it as often as you need.
