How to Combine Multiple Files Into One PDF

To combine files into one PDF, merge existing PDFs with a merge tool, or convert photos and scans to PDF first and then merge. It takes a few clicks and no software.

Combining PDFs you already have

If everything is already a PDF, you just need to merge them in the right order.

  • Open the Merge PDF tool and add all your files.
  • Drag them into the order you want; the pages follow that order exactly.
  • Merge and download a single document.

Combining photos and scans

Phone photos and screenshots are images, not PDFs, so convert them first.

  • For photographs, use JPG to PDF — each photo becomes one page.
  • For screenshots and graphics with sharp text, use PNG to PDF.
  • Then combine the results with existing PDFs using Merge PDF.

Common real-world jobs

  • Expense reports: merge a dozen receipt scans into one file for your accountant.
  • Job applications: combine a CV, cover letter and certificates into a single PDF.
  • Contracts: attach annexes behind a signed agreement in the correct order.

Why one file is better

A single PDF is easier to email, print and archive than a folder of loose files, and it locks the page order. Because these tools run in your browser, none of your documents are uploaded.

Frequently asked questions

Can I combine images and PDFs together?

Yes. Convert the images to PDF first (JPG to PDF or PNG to PDF), then use Merge PDF to combine those with your existing PDF files in any order.

Will combining files reduce quality?

No. Merging copies pages as-is without re-rendering, and converting images embeds them at their original resolution, so nothing is degraded.
