Merge PDF

Combine PDFs in the order you want, into one document.

This tool runs entirely in your browser. Your file is never uploaded to our server.

About this tool

Drop in two or more PDFs, drag them into the order you want, and download a single combined file. Bookmarks and page sizes from each source document are carried over as-is.

How to use this tool

  1. Select or drag in the PDF files you want to combine.
  2. Drag the file cards to set the order — the top file becomes page 1.
  3. Click Merge PDF and download the result.

How it works

Merging copies every page object from each source file into a new document in sequence. Nothing is re-rendered, so text stays selectable, images keep their original resolution, and the output size is roughly the sum of the inputs.

Frequently asked questions

Is there a limit on how many PDFs I can merge?
There is no fixed file-count limit. The practical ceiling is your device memory — merging dozens of large scanned PDFs at once may be slow on a phone. Merging in two passes solves this.
Are my files uploaded to a server?
No. The merge runs inside your browser using JavaScript. The files stay on your device and nothing is transmitted to us.
Will the merged file keep its text and links?
Yes. Pages are copied at the object level rather than re-rendered, so selectable text, internal links and embedded fonts survive the merge.
