Merge PDF

Join several PDFs into one file, in the order you set, right in your browser.

Your files will appear here.

What it does

Merge PDF joins two or more PDF files into one, so you can send, print or keep a single document instead of a handful of attachments. Every page of every file is copied in the order of the cards: the first card’s pages come first, then the next card’s, and so on.

The result shows how many files and pages went in and the size of the merged PDF before you save it.

How to use it

  1. Drop your PDFs on the box, paste them, or select Choose files. Select “Try a sample” to see two example PDFs merged.
  2. Put the files in order with Move up and Move down. The merged PDF is ready a moment after each change.
  3. Select Download to save the merged PDF. It’s named after the first file, such as report-merged.pdf.
  4. Press Ctrl+Enter (⌘+Enter on a Mac) to merge again, or Esc to stop a merge that’s still working.

Good to know

Privacy

Your PDFs are processed on your device: the tool runs in your browser and doesn’t upload them. The merged file starts without the originals’ document details, such as title, author and the app that made them. Comments and files attached to a page stay with that page, and comments keep their author names and dates. Pictures inside the pages are copied as they are, along with any data they carry.

Frequently asked questions

How do I change the order of the files?

Use Move up and Move down on a file's card. The PDFs are joined from the top card to the bottom one, and the merged file updates after each move. Each card shows where its pages land in the result, such as Pages 4–9, so you can check the order before you download.

What does the merged file keep?

Every page keeps its text, pictures, size and rotation. Comments and files attached to a page stay with that page, and comments keep their author and dates. Web links keep working, but links that jump to another page in the same file may not. Pictures inside the pages are copied as they are, with whatever data they carry, such as camera details in a scanned photo. The document's bookmarks and its list of attachments aren't kept, and neither are the files' title and author or the accessibility tags that give screen readers the reading order. Form fields don't stay fillable.

Why is a protected PDF refused?

A PDF that needs a password to open, or one its owner locked with restrictions such as no printing or copying, can't be merged. The tool doesn't remove protection someone else set. Open the file in the app you normally use, save a copy without the protection, then add that copy.

How many files and pages can I merge?

Up to 20 PDFs at once, each up to 100 MB and 200 MB together. The merged PDF can have up to 2,000 pages. Very large files can be slow on a phone, so merge them on a computer if you can.

Are my files uploaded?

No. Your PDFs are merged by your browser, on your device, and they aren't sent anywhere. The merged file is made on your device too, and it's saved only when you select Download.
