How to Merge PDF Files

  1. Click Select PDF Files and choose two or more PDFs, or drag them onto the page.
  2. Drag the file thumbnails into the order you want them to appear.
  3. Click Merge PDF and wait a few seconds.
  4. Download your combined PDF or save it to the cloud.

That's it. Your merged file keeps the original page sizes and quality, and the uploaded files are deleted from our servers automatically after processing.

Why merge PDF files?

Sending one document is cleaner and more professional than attaching ten. Merging PDFs makes it easy to keep related pages together, avoid missing attachments, and meet upload forms that accept only a single file.

  • Combine a resume, cover letter and certificates for a job application.
  • Join scanned pages of a form or ID into one submission.
  • Put monthly invoices or bank statements into one yearly file.
  • Assemble chapters of a report, thesis or eBook.

Features of Our PDF Merger

Unlimited order control

Rearrange files with simple drag and drop before merging. Prefer to sort automatically? Name your files 01, 02, 03 and they will line up in order.

Quality stays the same

Merging does not re-compress your pages, so text, images and vector graphics look exactly like the originals.

Fast and free

Merge PDF online without installing software or creating an account. There is no watermark added to your document.

Private and secure

Files travel over encrypted HTTPS and are removed automatically after processing. We never look at the content of your documents.

Tips for the best result

If the merged file is too big to email, run it through Compress PDF afterwards. If you only need certain pages from a file, use Split PDF first, then merge the parts you want. Have photos instead of PDFs? Convert them with JPG to PDF.
