PDF Merger

Merge two or more PDF files into one. Reorder pages by dragging, then download a single combined document — all in your browser.

Your PDFs are merged entirely in your browser. They are never uploaded to our servers.

How to use PDF Merger

  1. Add the PDF files you want to combine — drag them in or click to browse.
  2. Drag the file cards to set the order.
  3. Press “Merge PDF”.
  4. Download the combined document.

About this tool

Whether you are assembling a report from several sections, combining scanned pages, or collecting invoices into one file, merging PDFs saves you from juggling many separate documents.

The merger keeps each page exactly as it is and simply joins the files into one. Because the work happens in your browser, even confidential documents never leave your device.

When to use it: to combine scans, chapters, forms or attachments into one document before sending or archiving.

Frequently asked questions

Can I change the order of pages?
Yes. Before merging, drag the file cards into the order you want. The merged PDF follows that order page by page.
Is there a limit on the number or size of files?
You can merge as many files as you like. Very large files use more memory, so very big PDFs work best on a desktop browser.
Does merging reduce the quality of the PDF?
No. The pages are copied into the new document without re-rendering or re-compressing the content.
Are my files uploaded to a server?
No — the merge runs entirely in your browser, which makes it safe for confidential documents such as contracts and statements.
Do bookmarks and form fields survive merging?
Pages are copied as they appear. Bookmarks are not carried over, and interactive form fields may be flattened to their visible content.
Why is the merged file size not exactly the sum of the inputs?
Each PDF carries its own fonts and metadata, and the merged document shares what it can — so the total is usually close to, but not exactly, the sum.
