Merge PDF – Combine Several PDFs into One File, in Any Order

A free tool that combines several PDF files into one, in the order you choose. Each file shows its first page and page count, and you can drag to reorder them. Pages are copied as they are, so quality doesn’t change, and your files are processed in your browser.

Your files are processed in your browser and are never uploaded to a server.

When you need to merge PDFs

Many applications ask you to submit your documents as a single PDF. Merging helps when you need to:

  • Combine your résumé and work history for a job application
  • Put transcripts and recommendation letters together for a university application
  • Organize tax documents you scanned one at a time
  • Send a quote, invoice and delivery note to a client as one file
  • Turn several handouts into one set of meeting materials

Features

  • Each file shows a preview of its first page and its page count, so you can tell them apart at a glance
  • Press and hold (or drag on a computer) to reorder files freely
  • Choose which pages to take from each file (e.g. 1-3, 5)
  • Remove any file with “×”
  • Pages are copied as they are, so quality doesn’t change and text stays selectable and searchable
  • Preview the merged PDF before downloading

If a file can’t be merged

Password-protected PDFs, PDFs with editing restrictions and damaged PDFs can’t be merged. The tool shows the file name and the reason when you add it, and you can still merge the other files.

After merging

Combine it with other tools to fine-tune the page order or remove pages you don’t need. If merging photo-heavy or scanned PDFs made the file large, compress it before submitting.

Your files are never uploaded

Your PDFs aren’t uploaded to a server; they’re merged in your browser. Contracts and documents with personal information are never sent anywhere.

Using it on a phone

You can merge PDFs in iPhone and Android browsers too. Press and hold a file, then drag to change the order. For many large files, a computer is more comfortable.

Frequently asked questions

Q. Is it free?

A. Yes. It’s free with no usage limits, and no watermark is added.

Q. Can I merge only some pages?

A. Yes. Open “Choose pages to use” and enter pages for each file (e.g. 1-3, 5). Files left empty use all their pages.

Q. How many PDFs can I merge?

A. There’s no limit on the number of files. However, depending on your device’s memory, very large files in large numbers may not merge.

Q. Does merging lower the quality?

A. Fix them after merging with Rotate PDF.
