How to Merge PDF Files for Free (Combine PDFs into One)

The fastest free way to merge PDFs is to use an online tool like iLovePDF or Smallpdf — upload your files, drag them into order, and download one combined PDF. For a fully offline option, you can print multiple PDFs into a single file through a browser. Here are all the methods, plus how to handle common problems.

Which method should you use?

Method 1: Online merger (easiest)

Use iLovePDF Merge or Smallpdf Merge:

1. Click Select PDF files and upload all the files you want to combine.
2. Drag thumbnails to reorder them.
3. Optionally remove a page by clicking the trash icon on it.
4. Click Merge and download the combined file.

Both are free with daily limits and no watermark. They also let you rotate pages and mix files from your computer, Drive, or Dropbox.

Method 2: Google Chrome (offline, no upload)

Works if you have the PDFs open as browser tabs. Nothing leaves your computer.

1. Open the first PDF in Chrome.
2. Press Ctrl + P (or Cmd + P) and set destination to Save as PDF.
3. Repeat for each PDF, saving each to the same folder.
4. Reopen Chrome → drag all saved PDFs into one window so they appear as tabs, then print the whole window as a single PDF.

This is clunkier than an online tool, but keeps your documents entirely on your computer. Best when the files are confidential.

Method 3: Preview (Mac only, offline)

1. Open the first PDF in Preview.
2. View → Thumbnails, then drag the other PDF files’ thumbnails into the sidebar where you want them.
3. File → Export as PDF.

You can also drag individual pages between documents, so it doubles as a page-organizer.

Reordering and removing pages

Most mergers let you fix the order before combining:

• Reorder: drag the thumbnails into place.
• Delete a page: click the trash icon on that thumbnail.
• Rotate: use the rotate button on sideways pages.

Doing this before merging saves you from re-doing the whole job.

Common problems and fixes

After merging

If the combined file is large, reduce its size before sending. To sign or edit the result, see how to sign a PDF or how to edit a PDF. To pull pages back out, see how to extract pages from a PDF.

If the result is still too big to send, see reduce PDF size. To turn a finished document into a secure PDF instead, see how to password-protect a PDF.

FAQ

Is merging PDFs free?

Yes. iLovePDF and Smallpdf merge files free with daily limits. Mac’s Preview and Chrome’s print method are unlimited and offline.

Can I merge PDFs without uploading them anywhere?

Yes — use Chrome’s print-to-PDF (Method 2) or Mac’s Preview (Method 3). Both keep the files entirely on your computer.

Will merging change the quality or formatting?

No — merging concatenates the files as-is. Pages keep their original formatting, order, and quality. Need to change the text afterward? See how to edit a PDF.

How do I merge PDFs in a specific order?

Upload all files to a merger, then drag the thumbnails into the order you want before clicking Merge.

Can I merge JPG or Word files into a PDF too?

Yes — iLovePDF and Smallpdf also offer “JPG to PDF” and “Word to PDF”. Convert those to PDF first, then merge them with your other PDFs.

Is there a page or file limit?

Free tiers usually allow several files per task (often 10+) with daily task limits. For very large jobs, use the offline methods, which have no upload limit.

Can I merge PDFs on my phone?

Yes — the iLovePDF and Smallpdf mobile apps merge PDFs on iOS and Android, free with limits.
