How it works

1Choose two or more PDF files, or drag them onto the page.
2Drag the tiles or use Earlier and Later to set the order. Rotate or remove files you do not need.
3Pick an output name, then select Merge PDF.
4Download the merged file.

File order: Keep the order shown in the workspace, or sort the files by name from A to Z or Z to A.
Output file name: The name of the merged file. The .pdf ending is added for you.
Rotate: Turns every page of the selected files by 90 degrees each time you select it.
Duplicate: Adds a second copy of a file, useful for repeating a cover page or a form.

This tool runs in your browser. Your files are never uploaded to a server.

Are my PDFs uploaded anywhere?

No. Merging happens inside your browser with your own device. Nothing is sent to a server, so confidential documents stay private.

Is there a limit on files or pages?

There is no fixed limit. The practical limit is your device memory. Dozens of ordinary documents merge without trouble on most computers and phones.

Can I merge password-protected PDFs?

Not directly. Remove the password first with an unlock tool, then merge. Files that are encrypted show a clear message instead of failing silently.

Will the merged PDF keep links, bookmarks and form fields?

Page content, text and images are kept as they are. Interactive extras such as bookmarks can be dropped when pages are copied between documents.

Can I change the order after adding files?

Yes. Drag the tiles, or select one and use Earlier and Later. Undo and Redo bring back any step.

Does it work on my phone?

Yes. Choose files from your phone storage, use the toolbar buttons to reorder, and download the result.
