How to merge PDF files into one

Combining several PDFs into a single file — joining chapters, stapling a cover letter to a CV, bundling receipts — is one of the most common PDF tasks. This guide shows how to do it for free in your browser, in the exact order you want, without uploading a thing or hitting a daily limit.

The fastest way

Open Merge to PDF, add your files, drag them into order, and click Merge. Download the combined PDF. Done.

Step by step

  1. Open Merge to PDF.
  2. Drop in your PDFs — and any images (JPG, PNG, WebP) you want included.
  3. Drag the files into the order you want them to appear.
  4. Click Merge, then download the single combined PDF.

Mixing PDFs and images

You are not limited to PDFs. Merge to PDF will fold images into the same document, so you can append a photographed receipt or a signed, scanned page to a PDF form. If you only have images and want them turned into a PDF, Images to PDF is the dedicated tool for that.

The opposite job: splitting

Need to pull pages out instead of joining them? Use Split PDF to extract a page range or break a PDF into separate files.

If the merged file is large

Joining several PDFs adds up. If the result is too big to email, run it through Compress PDF to shrink it, which is especially effective on scanned pages.

A note on privacy

Merging often involves private paperwork — contracts, statements, applications. Merge to PDF assembles everything in your browser, so your files are never uploaded and nothing is stored after you close the tab.

Common questions

Can I merge PDFs and images together?

Yes. Merge to PDF accepts PDF files and images (JPG, PNG, WebP) in the same batch and combines them into one PDF, in the order you arrange them — handy for stapling a scanned receipt photo onto a PDF form.

How do I control the page order?

Add all your files, then drag them into the order you want before merging. The final PDF follows that order top to bottom, and each PDF contributes all of its pages in sequence.

Is there a file count or size limit?

There is no imposed limit and no daily cap. Everything is assembled in your browser, so the only practical limit is your device's memory — very large or numerous files use more RAM.

Are my PDFs uploaded to a server?

No. The files are read and merged entirely on your device. Nothing is transmitted, so confidential documents stay private and the tool works offline once loaded.
