Merge PDF Files

Upload several PDFs, put them in the order you want, and merge them into a single file. Everything happens in your browser.

Your document is processed directly in your browser and never uploaded to Numelto.

What it does

Combines two or more PDF files into one, keeping each one's original content, in the order you choose.

How it works

Every PDF you upload is added to the list with its name, size, and page count. You can reorder them with the arrows or remove one before merging — the result follows that exact order.

Privacy

Merging happens with a library that runs in your own browser (pdf-lib). No file is ever uploaded to Numelto or any other server.

When merging PDFs comes in handy

If you later need to remove extra pages, use delete pages; to change the order at the page level, use organize PDF; and if the result is too heavy, use compress PDF.
