Merge PDF Files

Combine two or more PDF files into one document in your browser. Pages keep their original order, and nothing is uploaded to a server.

About Merge PDF Files

This tool joins several PDF files into a single document. Add two or more PDFs (up to 50 MB each), and every page from each file is copied into a new PDF in the order the files were added. The combined file downloads as merged-document.pdf.

All processing happens in your browser with a JavaScript PDF library, so your documents are never sent to a server. It is useful for bundling a cover letter with a resume, combining scanned receipts, or collecting chapter files into one report. Pages cannot be reordered or removed here, so add the files in the order you want them to appear. Password-protected PDFs cannot be opened.

How to use it

  1. Drop two or more PDF files onto the upload area, or click to select them.
  2. Check the list of loaded files; use Clear Files to start over if the order is wrong.
  3. Click Merge PDFs Now.
  4. Save the downloaded merged-document.pdf.

Questions

Are my PDFs uploaded anywhere?

No. The files are read and combined by code running in your browser, and the result is saved directly to your device.

How is the page order decided?

Files are merged in the order you added them, and each file's pages keep their original sequence. To change the order, clear the list and add the files again in the order you want.

Can I merge password-protected PDFs?

No. Encrypted PDFs cannot be opened by this tool, so remove the password with the software that created the file first.

Is there a size limit?

Each file can be up to 50 MB. Very large merges depend on your device's available memory.
