—About Merge PDF
Merge PDF combines several PDF files into a single document, in an order you control, entirely inside your browser. It fits anyone assembling reports, scanned pages, or signed forms into one file without installing desktop software.
Combining PDFs usually means uploading confidential documents to a web service. Doing it locally keeps contracts, statements, and records on your own machine while still giving you a clean merged file.
Step by step
- Add the PDFs you want to combine by dropping them in or selecting them from disk.
- Drag the files into the order you want them to appear in the final document.
- Confirm the arrangement in the list preview.
- Click Merge to assemble them into one PDF.
- Download the combined file to your device.

Tips for best results
- Name files in advance if order matters; it makes arranging them faster.
- Very large or scanned PDFs use more memory — close other heavy tabs if a big merge feels slow.
- Check the page count of the result against the sum of the inputs to confirm nothing was missed.

Common questions
This runs entirely in your browser
No file or text you enter here is uploaded. Encoding and decoding happen on your device using native browser APIs — close the tab and nothing remains on a server.
