Merge PDF files online
Combine several PDFs into a single document, in the order you choose. Merging happens in your browser, so your files never leave your device.
How to merge PDF files
- Add your PDFs
Drop the files on the box above or choose them from your device. You can add up to 30 files at once.

Your files never leave your device
Most online PDF services upload your documents to their servers. PDFellow does the work right here in your browser, so your file is never sent anywhere. It’s free, there’s no signup, and you can use it as often as you like.
Frequently asked questions
Is merging PDFs really free?

How many files can I merge at once?
Up to 30 PDFs in one go, each up to 80 MB. For more, merge them in batches and then merge the results.
Can I merge password-protected PDFs?
Remove the password first with Unlock PDF, then merge the unlocked copy.
