About Merge PDFs

Merge PDF joins several documents into one, keeping every page in the order you set and leaving the pages themselves untouched.

Runs entirely in your browser. Your files never leave your device.

How to use it

1.Add the PDFs you want to combine and check the file names before going on.
2.Drag the files into the order their pages should appear in.
3.Merge, open the result, and check the first and last page of each section came through.

Options

The file order is the page order. Nothing is reshuffled after that.
Pages keep their original size, so an A4 file and a Letter file can sit in the same document.

Limitations

Bookmarks, form fields, signatures, and document metadata do not always survive the merge.
Merging will not shrink a big scan or make its text searchable.

Common questions

Can I merge PDFs with different page sizes?

Yes. Every page keeps its own size, so you can end up with a document that mixes portrait, landscape, A4, Letter, and custom pages.

Why is a digital signature invalid after merging?

A signature covers an exact sequence of bytes, and merging writes a new file. Sign the combined PDF at the end instead of merging files that are already signed.
