Merge PDFs
This free Merge PDF tool combines two or more PDF files into one document in whatever order you choose. Drop your files in, reorder them, and the merge happens entirely on your device — nothing is uploaded.
How to use Merge PDFs
- 1 Drop your PDFs onto the drop zone, or click to browse and add two or more files.
- 2 Reorder the list with the up and down arrows, or remove any file with the X.
- 3 Click Merge to combine them into a single PDF.
- 4 Preview the result, then download the merged file — your PDFs never leave your browser.
Frequently asked questions
Are my PDFs uploaded to a server to merge them?
No. The merge runs completely in your browser, so your documents stay on your device. Nothing is uploaded, which keeps confidential contracts and records private.
Can I control the order of the merged pages?
Yes. Each added file appears in a numbered list, and you can move any file up or down before merging so the final document is in exactly the order you want.
How many PDFs can I combine at once?
You need at least two files, and you can add as many as you like. Everything is processed locally, so very large batches depend on your device's memory.
Does the merge tool work offline?
Yes. PDFPowerHub is a PWA, so once the page has loaded you can merge PDFs with no internet connection.
