Merge PDF
Combine several PDF files into one, in the order you choose, without uploading them anywhere.
Drop a file here, or click to choose one
The PDFs never leave your browser: they are joined here.
The result has the pages in the order of the list, with the filenames, sizes and any rotation each one brought. The originals are not touched.
What does this tool do?
Joins several PDF files into one, in the order they appear in the list. Each file keeps its own pages, its page sizes and any rotation it already had, and the result is a new document.
Why the list and not dragging
The usual way to reorder files is dragging them around, which needs to hit a drop zone and does not exist on a phone. Up and down arrows always work, and they show the order that is going to be used.
What it tells you before merging
The page count of each file, and the total. That is not decoration: merging the wrong version of a contract is a mistake you notice afterwards, and seeing “3 files · 24 pages” before pressing the button is what stops it. If a file cannot be read — it is not a PDF, or it is password-protected — it is named and the merge is blocked rather than silently skipping it.
Keep in mind
Nothing is uploaded. Files are read, joined and written in your browser, and the originals are not touched.
