Merge PDF

Combine PDFs into a single document in the order you choose. Nothing is uploaded.

Add at least two PDFs to merge.

How merging PDFs works

Add two or more PDFs, arrange them with the arrows, and press Merge. Every page from every file is copied into one new PDF, in list order, keeping its original size and content. Your original files aren't changed.

Merging happens entirely in your browser, so it's safe for contracts, invoices, and other private documents.

Frequently asked questions

Can I merge password-protected PDFs?
Not yet. Remove the password in your PDF reader first, then add the file here.
Will the merged PDF lose quality?
No. Pages are copied as they are — text, images, and vector graphics stay exactly the same.
How do I merge only some pages?
Use Split PDF to extract the pages you want first, then merge the results here.
Are my files uploaded?
No. Merging runs in your browser and your PDFs never leave your device.
