Open Madosuite
PDF, free, no upload

Merge PDF files free, without uploading them

Combine any number of PDFs into one file in your browser. Each file becomes a bookmark, with its own bookmarks nested underneath, and links and form fields keep working.

How to do it

  1. Open Madosuite and upload the PDFs in Files.
  2. Open the first one in the PDF app.
  3. Choose Combine files and add the others in the order you want.
  4. Save the combined PDF and download it from Files.

What it keeps

  • Links
  • Form fields, still interactive
  • Each file’s bookmarks, nested under a bookmark of its own
  • Layers and attachments

Limits today

  • The PDF app is alpha. Look through the merged file before you send it.
  • There is no printing from the browser version: download the file and print it from your computer.

Your PDF stays on your device

The PDF opens in the PDF app inside Madosuite’s Linux machine, in your browser. It is not uploaded to us, which matters for contracts, medical letters and anything with a signature on it.

Questions

How many PDFs can I merge?

Any number, as the PDF app’s documentation puts it. Very large files need a computer with enough memory, because everything runs on your device.

Will the pages look the same?

Every page of a combined document renders the same as its source, according to the app’s documentation.

Can I change the page order afterwards?

Yes. Move pages earlier or later, rotate them or delete them in the same app, and undo any step.

Is my PDF uploaded?

The PDF opens in the PDF app inside Madosuite’s Linux machine, in your browser. It is not uploaded to us, which matters for contracts, medical letters and anything with a signature on it.

Is Madosuite free?

Yes. The apps run on your own device, in the browser tab, so there is no server time to pay for. There is no trial period.
